Other Special Sprockets
- A line-up of special sprockets is also available.
- We offer sprockets for BS/DIN Series chain and torque limiters to meet customer needs.
- *Sprockets for BS Chains :Standard BS/DIN products (Available chain sizes :RF06B~RS16B)
- *Torque Limiter Sprockets :Finished on the friction surface of the center member. (Available chain sizes :RS40~RS100)
Sprockets for BS Chains
- BS standard (European standard) roller chains require special BS sprockets.
(RS sprockets/JIS standards cannot be used due to a different tooth width and outer diameter. ) - Sizes, hardened teeth specifications, and bore finishings not shown in the dimensional chart are also available on an MTO basis. Contact us for more information.
- Sizes not shown in the dimensional chart are also available on an MTO basis (For example: 20B, 56B). Contact us for more information.
Dimensions, Specifications
Note) When selecting sprocket specifications
・It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used. For details, please refer to the compatibility table for each chain and sprocket.
・Shaft bore remains as a pilot bore, so it must be machined by the customer before use. Click here if you require a product with a finished bore
Torque Limiter Sprockets
- Torque limiters are typical mechanical devices for overload protection, and such it is essential that the friction surface of their center member be finished properly to ensure the precise, accurate overload detection of the torque limiter.
- Sprockets for torque limiters are provided with special surface finishing to realize the ideal surface roughness.
