Taper Bore Sprockets \u2013 Product Overview<\/h2>\n
\n
\n

Korea Ever-Power taper bore sprockets to DIN 8187 \/ ISO R606 are supplied pre-machined to accept the standard taper lock bush series \u2014 1008 through 5050 \u2014 covering shaft diameters from 12 mm to approximately 125 mm depending on bush size. The taper bore replaces the conventional keyed bore and setscrew arrangement with a precision-ground internal taper that mates with the external taper of the split taper lock bush. When the bush cap screws are tightened, the taper generates a large compressive clamping load on the shaft without requiring a key for rotational drive \u2014 the friction grip alone is sufficient for all rated drive loads.<\/p>\n

The most important practical advantage of taper bore sprockets is removal without shaft damage. Loosening the cap screws and reinserting them in the ejection holes of the bush pushes the bush free of the sprocket taper \u2014 the sprocket and bush separate cleanly from the shaft in seconds with no hammer, puller or heat required. This is the critical difference from a parallel-keyed bore, where removing a sprocket without a puller risks shaft and bearing damage, and where hammering the sprocket free can introduce shock loads into the adjacent bearing. For any drive where sprockets must be changed more than once a year, the time and tooling saved by taper bore mounting justifies the additional initial cost.<\/p>\n

Taper bore sprockets are manufactured in three hub configurations: TS (simplex\/single strand)<\/strong> for single-chain drives, TD (duplex\/double strand)<\/strong> for two-strand chain drives, and TT (triplex\/triple strand)<\/strong> for three-strand drives. The hub bore for all three configurations is the same for a given chain size and tooth count \u2014 the difference is the overall hub width, which increases with each additional strand. Browse the complete sprocket range<\/a> for other mounting configurations.<\/p>\n

Materials: standard grade is C45 carbon steel with induction-hardened tooth flanks. Cast iron (G22) variants are available for abrasive environments where graphite lubricity reduces tooth wear \u2014 see our cast iron sprocket range<\/a> for details. Taper lock bushes are not included \u2014 specify the bush code and shaft diameter separately. Pair with matched European standard roller chain to DIN 8187<\/a> for a complete factory-direct drive package.<\/p>\n<\/div>\n
