Sproket Lubang Jadi Standar Asia \u2013 Gambaran Umum Produk<\/h2>\n
\n
\n

Rentang lubang akhir diproduksi dalam dua jenis hub: FBN (Tipe B)<\/strong> \u2014 sebuah hub lurus dengan lubang, alur pasak, dan sekrup pengunci, dilengkapi dengan alur pasak yang berpusat pada garis tengah gigi (bukan di antara gigi seperti pada beberapa standar lain). Susunan alur pasak di tengah gigi memungkinkan pasak terlihat dari atas saat sproket dipasang pada poros, sehingga memudahkan pemeriksaan keselarasan. FBK (Tipe B+F)<\/strong> \u2014 hub yang sama dengan flensa tambahan, digunakan untuk aplikasi yang memerlukan penahan lateral positif atau pemasangan ke bahu poros.<\/p>\n

The range covers chain sizes 25B (3\/16″ pitch) through 120B (1\u00bd” pitch), in simplex. Material is C45 carbon steel with induction-hardened teeth for sizes 35B and above. For 25B light-duty chain, the sprocket is un-hardened plain C45. Stainless steel (SUS304) variants are available for 25B (food and pharmaceutical) \u2014 designated SUSFBP.

Untuk jarak ulir yang sama (misalnya \u00bd\u2033 \/ 12,7 mm), ketiga standar tersebut memiliki diameter rol yang berbeda:<\/p>\n\n\n\n\n\n\n

\n

Lokasi Keyway \u2014 Perbedaan Standar Asia<\/h2>\n

Sproket standar Asia memiliki alur pasak yang dikerjakan pada garis tengah gigi \u2014 sejajar dengan titik tengah gigi, bukan di antara gigi. Ini merupakan konvensi yang berbeda dari sproket standar Eropa DIN 8187 dan Amerika ANSI B29.1, di mana alur pasak biasanya diposisikan di antara gigi. Perbedaan ini penting karena dua alasan:<\/p>\n

\n
\n

\u2714 Konfirmasi Pemasangan Visual<\/p>\n

Dengan alur pasak pada garis tengah gigi, teknisi dapat memastikan posisi pemasangan yang benar dengan melihat bagian atas sproket yang terpasang \u2014 gigi yang tepat di atas pasak harus berada di tengah tanda alur pasak pada poros. Pemeriksaan visual ini sangat berguna selama pemasangan sproket besar di mana mengukur posisi sproket sulit dilakukan.<\/p>\n<\/div>\n

\n

\u26a0\ufe0f Jangan Mengganti Sproket dengan Sproket Eropa\/ANSI<\/p>\n

Sproket standar Eropa atau ANSI tidak dapat digantikan dengan sproket standar Asia pada rantai Asia, meskipun jarak antar gigi dan diameter lubangnya sama. Profil gigi \u2014 radius lengkungan dudukan, lebar gigi, dan sudut gigi \u2014 berbeda antar standar. Menggunakan rantai dan sproket yang tidak sesuai akan menyebabkan kontak rol yang buruk, keausan yang dipercepat, dan kegagalan sproket prematur dalam beberapa minggu setelah pemasangan.<\/p>\n<\/div>\n

\n

\ud83d\udcd0 Standar Alur Pasak JIS B1301<\/p>\n

Dimensi alur pasak sesuai dengan JIS B1301 (revisi 1976) \u2014 standar Jepang untuk pasak paralel dan alur pasak pada ukuran lubang metrik. Dimensi ini mendekati DIN 6885 tetapi menggunakan proporsi kedalaman yang sedikit berbeda untuk ukuran lubang kecil (di bawah 22 mm). Selalu gunakan pasak JIS B1301 atau DIN 6885 pada sproket standar Asia \u2014 jangan gunakan pasak inci ASME B17.1, yang memiliki rasio lebar terhadap kedalaman yang berbeda.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Profil Gigi JIS B1801<\/h3>\n

Profil gigi sesuai dengan JIS B1801 \u2014 yang diperlukan untuk pemasangan yang benar dengan rantai rol standar Asia. Radius kurva dudukan dan lebar gigi berbeda dari DIN 8187 dan ANSI B29.1 karena diameter rol standar Asia sedikit berbeda dari keduanya. Menggunakan rantai Asia pada sproket Eropa atau Amerika (atau sebaliknya) menyebabkan dudukan rol yang tidak tepat dan keausan dini meskipun jarak antar gigi identik. Pasangkan dengan Rantai rol standar Asia JIS B1801<\/a>.<\/p>\n<\/div>\n

\n

C45 dengan Gigi yang Dikeraskan \u2014 35B dan Di Atasnya<\/h3>\n

Semua sproket FBN dan FBK dalam ukuran 35B hingga 120B terbuat dari baja karbon C45 dengan sisi gigi yang dikeraskan secara induksi pada kekerasan 52\u201358 HRC. Lubangnya dikerjakan sebelum siklus perlakuan panas dan dikonfirmasi dimensinya setelah pengerasan. Sproket 25B lebih ringan \u2014 C45 polos tanpa pengerasan gigi, cocok untuk beban ringan pada aplikasi penggerak 25B. Varian stainless steel SUS304 (awalan SUSFBP) hanya memiliki lubang polos dan tidak dikeraskan materialnya.<\/p>\n<\/div>\n

\n

Tipe Flensa FBK \u2014 Retensi Lateral<\/h3>\n

Tipe FBK menambahkan permukaan flensa pada hub, menyediakan permukaan bantalan terhadap bahu atau kerah poros. Ini diperlukan dalam aplikasi di mana sproket harus ditahan secara aksial pada poros oleh geometrinya sendiri daripada sepenuhnya bergantung pada sekrup pengunci. FBK adalah tipe standar untuk penggerak rantai pada mesin pertanian dan peralatan penanganan material Jepang di mana posisi sproket ditentukan oleh langkah poros daripada hanya oleh sekrup pengunci.<\/p>\n<\/div>\n

Asian Standard Finished Bore Sprockets \u2013 Product Overview<\/h2>\r\n
\r\n
\r\n

The finished bore range is produced in two hub types: FBN (Type B)<\/strong> \u2014 a straight hub with a bore, keyway and setscrew, supplied with the keyway centred on the tooth centreline (not between teeth as in some other standards). The keyway-on-tooth-centre arrangement allows the key to be visible from above when the sprocket is mounted on the shaft, making alignment checks easier. FBK (Type B+F)<\/strong> \u2014 the same hub with an additional flange, used for applications requiring positive lateral retention or attachment to a shaft shoulder.<\/p>\r\n

The range covers chain sizes 25B (3\/16\" pitch) through 120B (1\u00bd\" pitch), in simplex. Material is C45 carbon steel with induction-hardened teeth for sizes 35B and above. For 25B light-duty chain, the sprocket is un-hardened plain C45. Stainless steel (SUS304) variants are available for 25B (food and pharmaceutical) \u2014 designated SUSFBP.

\r\n

Keyway Location \u2014 Asian Standard Difference<\/h2>\r\n

Asian standard sprockets have the keyway machined on the tooth centreline \u2014 aligned with the midpoint of a tooth, not between teeth. This is a different convention from European DIN 8187 and American ANSI B29.1 sprockets, where the keyway is typically positioned between teeth. The difference matters for two reasons:<\/p>\r\n\r\n

\r\n
\r\n

\u2714 Visual Installation Confirmation<\/p>\r\n

With the keyway on the tooth centreline, the engineer can confirm correct installation position by looking at the top of the installed sprocket \u2014 the tooth directly above the key should be centred over the keyway mark on the shaft. This visual check is particularly useful during installation of large sprockets where gauging the sprocket position is difficult.<\/p>\r\n\r\n<\/div>\r\n

\r\n

\u26a0\ufe0f Do Not Substitute European\/ANSI Sprocket<\/p>\r\n

A European or ANSI sprocket cannot be substituted for an Asian standard sprocket on Asian chain, even if the pitch and bore are the same. The tooth profile \u2014 seating curve radius, tooth width and tooth angle \u2014 differs between standards. Running mismatched chain and sprocket causes poor roller engagement, accelerated wear and premature sprocket failure within weeks of installation.<\/p>\r\n\r\n<\/div>\r\n

\r\n

\ud83d\udcd0 JIS B1301 Keyway Standard<\/p>\r\n

Keyway dimensions conform to JIS B1301 (revised 1976) \u2014 the Japanese standard for parallel keys and keyways in metric bore sizes. This is dimensionally close to DIN 6885 but uses slightly different depth proportions for small bore sizes (below 22 mm). Always use a JIS B1301 or DIN 6885 key in Asian standard sprockets \u2014 do not use ASME B17.1 inch keys, which have different width-to-depth ratios.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n

JIS B1801 Tooth Profile<\/h3>\r\n

The tooth profile conforms to JIS B1801 \u2014 required for correct engagement with Asian standard roller chain. The seating curve radius and tooth width differ from DIN 8187 and ANSI B29.1 because the Asian standard roller diameter is slightly different from both. Running Asian chain on European or American sprockets (or vice versa) causes incorrect roller seating and premature wear even where the pitch is identical. Pair with JIS B1801 Asian standard roller chain<\/a>.<\/p>\r\n\r\n<\/div>\r\n

\r\n

C45 with Hardened Teeth \u2014 35B and Above<\/h3>\r\n

All FBN and FBK sprockets in 35B through 120B are C45 carbon steel with induction-hardened tooth flanks at 52\u201358 HRC. The bore is machined before the heat treatment cycle and confirmed dimensionally after hardening. 25B sprockets are lighter duty \u2014 plain C45 without tooth hardening, suitable for the light loads in 25B drive applications. SUS304 stainless variants (SUSFBP prefix) are plain bore only and are unhardened by material.<\/p>\r\n\r\n<\/div>\r\n

\r\n

FBK Flange Type \u2014 Lateral Retention<\/h3>\r\n

The FBK type adds a flange face to the hub, providing a bearing face against a shaft shoulder or collar. This is required in applications where the sprocket must be retained axially on the shaft by its own geometry rather than relying entirely on the setscrew. FBK is the standard type for chain drives in Japanese agricultural machinery and material handling equipment where the sprocket position is located by a shaft step rather than by a setscrew alone.<\/p>\r\n\r\n<\/div>\r\n

Korea Ever-Power for Asian OEM Drives<\/h3>\r\n

Korean industrial machinery uses JIS-based chain standards for all domestic drives. Korea Ever-Power Asian standard finished bore sprockets are the correct replacement for drives in Korean-manufactured equipment across all sectors \u2014 construction machinery, agricultural equipment, industrial conveyors and textile machinery. The same hub geometry, bore sizes and keyway dimensions as the original Korean OEM specification.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n
