Conveyor Chain - Product Overview

Korea Ever-Power conveyor chains form the largest and most diverse product group in the EP chain range, spanning simple double pitch conveyor chains for light assembly line work through to massive forged link chains for quarry conveyors and cement plant kilns. The range covers every principal chain type used in conveying applications: small pitch roller chain with attachments, double pitch roller conveyor chain (C-series), large pitch conveyor chain (M-series), hollow pin conveyor chain (HP series), free-flow conveyor chain (FV/FVT series), sharp top chain, slat chain, and specialty chains for food, automotive, parking, and timber industry applications.

Unlike driving chains, which transfer torque between two sprockets, conveyor chains transport a load along a path. This distinction has major engineering consequences: conveyor chains typically run at low speed but carry high loads distributed across their entire running length; the chain may travel for hundreds of metres and negotiate horizontal curves, vertical bends, and elevation changes in the same circuit; and the chain must interface with chain guides, wear strips, buckets, slats, flights, or product-carrying pallets. The EP conveyor chain range is designed with these conveying-specific requirements in mind, with larger pin-to-bush clearances for contamination tolerance, tighter pitch tolerances for smooth guide running, and a comprehensive attachment catalogue.

All EP conveyor chains are manufactured to ISO 1977 (metric large pitch roller chains) or ANSI B29.2 (double pitch roller chains) dimensional standards as applicable to the series. Attachment types follow ISO 1977 designation (A1, A2, K1, K2, G1, G4, D1, D2). Carbon steel, heat-treated alloy steel, and stainless steel variants are available across all major series. EP stocks all common series in standard 10-metre coils and can also supply cut-to-length chains with fitted end connections for direct installation.

Double Pitch Conveyor Chains (C Series)

Double pitch chains use the same roller diameter and inner width as the standard short pitch equivalent but with pitch doubled. This halves the number of links per metre and reduces chain cost for the same working load on low-speed conveyors. Standard: ANSI B29.2. C2040 corresponds to ANSI 40 roller chain pitch (12.7 mm) doubled to 25.4 mm.

Specialty Conveyor Chain Series

EP-HP Hollow Pin Conveyor Chains

The pin bore is hollow throughout its length, allowing steel rods or cross bars to pass through the pin axis. This enables buckets, flight bars, slats, or side guards to be mounted at any pitch without welding or drilling the chain plates. Used extensively in bucket elevator chains, bottling line guide bar installations, and packaging machine cross-bar conveyors.

Pitch: 25.4 mm to 76.2 mm. Carbon steel and SUS304 available. Bore diameter from 6 mm to 32 mm depending on chain size.

EP-FV / EP-FVT Free-Flow Chains

Free-flow chains carry outboard rollers on extended link plates that support pallets or carriers on guide rails independently of the chain tension. The pallet can accumulate against a stop while the chain continues to run beneath it - this "free flow" or "accumulation" function is the standard method for automotive engine and body assembly line conveying, where workpieces must stop at each assembly station without halting the conveyor.

EP-FV: flat outer roller. EP-FVT: wider outboard roller for heavier pallet support loads. Pitch 38.1 to 152.4 mm.

EP-MT Flat Top Chains

A flat steel or stainless plate is welded to the outer link, covering the roller and providing a continuous flat surface for direct product contact. Products slide or sit on the flat top surface rather than on a belt. Flat top chains are used in food conveying, tobacco manufacturing, printing press feed, and glass bottle conveying. Hinge type flat top chains with articulated slats allow horizontal curve operation.

Pitch 38.1 to 76.2 mm. Plate width 38 mm to 300 mm. Stainless steel option for food contact.

EP Sharp Top Chains

The outer link plate has a pointed raised profile running across the width of the chain, providing a gripping tooth that digs into soft materials on inclined conveyors. Used in sawmill timber sorting lines to prevent logs from rolling back on steep inclinations, and in aggregate quarries to move loose stone on steep-angle conveyors that would cause smooth-plate chain to slip.

Pitch 25.4 mm to 50.8 mm. High-carbon hardened plate for wear resistance against abrasive materials.

EP Escalator Step Chains

Precision conveyor chains for passenger escalators and moving walkways, manufactured to EN 115 (European) and ASME A17.1 (American) standards. EP escalator chains feature precision-ground pins, case-hardened bushes, and tight pitch tolerances to maintain step alignment and smooth passenger transition at landings. Step attachment holes are drilled and reamed to OEM specifications for major escalator brands.

Pitch 133.33 mm and 146.05 mm. Available for Otis, Schindler, Kone, ThyssenKrupp, and other major brands.

EP Mechanical Parking Chains

Forged alloy steel chains for multi-storey mechanical car parking systems, where vehicles are transported on pallets that are moved laterally and vertically by chain-driven mechanisms. These chains must carry vehicle loads of up to 3,500 kg per pair of chains, operate reliably in outdoor environments, and resist fatigue at the very high number of loading cycles typical of a busy car park.

Pitch 76.2 mm to 152.4 mm. Forged carbon steel with heat treatment to ensure hardness and toughness. Working load factor 6:1 minimum.

Conveyor Chain Selection Guide

Selecting the right conveyor chain requires matching five key parameters. This guide summarises the decision path.

1. Total Chain Pull

Calculate the sum of: load mass x friction coefficient (horizontal), load mass x sin(angle) (incline), and chain self-weight resistance per metre x circuit length. Divide by chain count (pairs). This is the required working load; add a 5:1 safety factor to get the minimum breaking load for chain selection.

2. Speed and Sprocket Teeth

Low chain speed (below 0.5 m/s) allows larger pitch chains. Higher speed (above 1.0 m/s) requires smaller pitch to reduce chordal action and impact loading at the drive sprocket. Minimum tooth count for smooth low-speed conveying is 6 teeth; for speeds above 1 m/s use at least 9 teeth.

3. Environment

Abrasive or contaminated environments require wider pin-to-bush clearances, sealed joints (O-ring chain), or bushless designs for simpler cleaning. Wet or chemical environments: stainless steel. High temperature (over 250 degrees C): chrome-molybdenum alloy chain without rubber seals. Food contact: stainless plus NSF H1 lubrication.

4. Attachment Requirements

If the chain must carry flights, buckets, slats, or guides, specify the attachment type (K1/K2/A1/A2/G1/G4/D1/D2 or hollow pin) and the attachment pitch (every 1st, 2nd, 3rd... nth link). Heavier attachments may require a stronger chain than the bare load calculation indicates, due to dynamic bending loads at the attachment points.

5. Circuit Length and Joining

Total chain length must be a whole number of links. For very long circuits, calculate required link count and verify that the resulting exact length falls within allowable sprocket centre distance adjustment range. Specify connecting link type (spring clip, cotter pin, or pressed-in pin for permanent joints) when ordering. EP can supply chains with pre-fitted end links in cut-to-length format.

Applications

Bulk Material Handling

Cement clinker conveyors (EP-M56 to EP-M160), coal mine face conveyors and stage loaders (EP-M80 with special coalite plates), quarry stone conveyors (EP-M40 with sharp top plates), sand and gravel aggregate plants, and grain elevator bucket chains (EP-C2060H and EP-C2080H with A1 bucket attachments). The M series heavy pitch range is sized for the extreme loads in these applications, with cast barrel rollers available for highly abrasive materials where rolled steel rollers wear prematurely.

Automotive Assembly

EP-FV and EP-FVT free-flow chains for engine assembly lines, body-in-white lines, and final assembly floor conveyors. The accumulation function allows vehicles to stop at each workstation while the chain circulates continuously beneath the carrier pallet. Typical pitch in automotive assembly lines is 76.2 mm or 101.6 mm, running at 0.1 to 0.3 m/s. EP can supply matched rail systems and pallet components for complete assembly line installations.

Food and Beverage Processing

EP-MT flat top chains in stainless steel for meat, poultry, fish, fruit, and vegetable processing lines where a smooth, washable surface is required. EP-HP hollow pin chains with stainless cross bars for bottle conveying. EP-C2060 and EP-C2080 double pitch chains with A1 bucket attachments for fruit and vegetable elevators. All food contact chains are available with NSF H1 lubricant at factory and with stainless connecting hardware.

Cement and Process Plant

EP-M80 and EP-M112 chains for clinker pan conveyors that operate at temperatures up to 700 degrees C. EP M-series drag chain for cement mill inlet clinker conveying. Slat chain conveyors for raw meal and clinker handling at intermediate plant sections. For high-temperature kiln chain curtain applications, EP supplies alloy steel chains with ceramic heat shields on request. Chain life in these applications is measured by elongation over an annual maintenance cycle.

Frequently Asked Questions

What is the difference between a conveyor chain and a driving chain?
Driving chains (short pitch roller chains) transfer torque between two sprockets at moderate to high speed. They are optimised for high cycling fatigue strength, low weight, and high-speed sprocket meshing. Conveyor chains transport loads along a track at low speed. They are optimised for high tensile load capacity, wear resistance in contaminated conditions, and the ability to carry attachments (flights, buckets, slats). Conveyor chains are generally heavier and more massively built than driving chains at the same pitch, and they use a different (wider, more open) tooth form on the sprockets. The two types are not interchangeable.
How do I choose between a C series double pitch chain and an M series large pitch chain?
C series double pitch chains (C2040 through C2162H) are derived from standard roller chain dimensions and are designed for light to medium conveying at low cost. They are suitable for assembly line, packaging, food conveying, and agricultural applications. M series large pitch chains (M20 through M315) are designed from the outset as heavy duty conveyor chains per ISO 1977, with heavier plates, larger pins, and wider inner widths at equivalent pitch. They are the correct choice for bulk material handling, cement, quarry, and steel works applications. The crossover point is approximately 3 tonnes of chain pull and 100 mm pitch, where M series becomes the only appropriate choice. Below these values, C series may suffice if the environment is not abrasive and if the required attachments are available in the C series range.
Can you supply conveyor chains with attachments already fitted?
Yes. EP supplies conveyor chains with factory-fitted attachments in any standard ISO 1977 or ANSI B29.2 attachment type (K1, K2, A1, A2, G1, G4, D1, D2) and at any link spacing (every link, every 2nd link, every Nth link). For hollow pin chains, the hollow pin pitch and bore diameter are specified at the time of order. Custom attachment profiles produced to buyer drawings are also available with a minimum order quantity. Supply the following information for an attachment chain quotation: chain model number and standard, attachment type and profile, attachment spacing (links between attachments), total chain length, and the required number of connecting links or end link configuration. Minimum order for standard attachment chains is typically one full coil (10 metres).
What chain should I specify for a cement clinker conveyor at 300 degrees C?
Cement clinker conveyors require M series heavy pitch chains in the EP-M56 to EP-M160 range depending on the conveyor width and clinker throughput rate. At 300 degrees C, standard carbon steel chains with conventional mineral oil lubricant can be used, but the lubrication interval must be reduced to account for accelerated oil oxidation. Above 400 degrees C, chrome-molybdenum alloy steel chains without rubber O-ring seals are required, with dry lubricant (molybdenum disulfide paste or graphite suspension). Above 600 degrees C, heat-resistant alloy steel and ceramic-coated heat shields are required. For clinker pan conveyors, also specify the pan attachment type and centre distance between chain centrelines. EP has standard configurations for most common clinker conveyor widths from 600 mm to 2,000 mm.
How do I calculate when a conveyor chain needs replacement?
Conveyor chain wear is measured by elongation. As the pin and bush wear, each pitch increases slightly, and the total elongation builds up over the length of the chain. Replacement is required when elongation reaches 2% to 3% of nominal length (depending on the application). For a chain of N links at pitch P, measure the total length of a 10-link section under slight tension and compare to 10P. If the measured length exceeds 10P by 2% (for precision applications) or 3% (for less critical conveyors), plan replacement. Also check for: roller wear (loose or wobbling rollers), plate cracking (especially at attachment weld points), pin corrosion, and stiff joints that fail to articulate freely around sprockets.
Are EP free-flow chains compatible with existing pallet systems from other suppliers?
EP-FV and EP-FVT free-flow chains follow the standard FV/FVT geometry that has been widely adopted in the industry, and EP chains at the same pitch and outboard roller width are generally dimensionally compatible with rail systems and pallets designed to that standard geometry. However, outboard roller height, plate thickness, and connecting link design do vary between manufacturers at the same nominal chain designation. Before fitting EP free-flow chains into an existing installation, verify the outboard roller diameter and height, the chain plate overall height, and the connecting link type against the original chain specification. Supply a sample of the original chain if possible and EP will provide a dimensional comparison before delivery.
