Roller chain coupling
Model number Body: CR□□□□H Case: CR□□□□K
This is a flexible coupling in which a double-strand roller chain is wound around two sprockets.
- The main body is made up of two rows of roller chains and two sprockets. The chain is connected by wrapping it around the sprockets and separated by removing it, so it can be connected and separated without moving the device.
- ・Excellent durability:
Rotational force is shared between the strong roller chain and the surface-hardened sprocket teeth, providing excellent durability.
It will be demonstrated. - ・Absorbs large misalignments:
The clearance between the components accommodates large misalignments on both shafts. - ・A wide variety of varieties:
In addition to the 15 varieties that comply with JIS standards, we have standardized 9 varieties, for a total of 24 varieties. - ·case:
Prevents lubricant from scattering and dust from entering, extending the life of the coupling (sold separately).

Roller chain coupling stainless steel series
Model number Body: CR□□□□H-SS Case: CR□□□□K-SS
Austenitic stainless steel is used for the roller chain and sprockets.
- ・Excellent corrosion resistance:
Suitable for use outdoors or in corrosive atmospheres such as acidic or alkaline. - ・Using temperature range:
Without case: -20 to 200°C With case: -10 to 80°C
*Please contact us if you plan to use the product with a case at temperatures exceeding 80°C. - ・Clean quality:
It has high rust prevention properties and is highly compatible with fluorine-based greases for food machinery and clean rooms. - ・Five large sizes added:
Five sizes have been added, from CR8018 to CR12022. - ・Quick delivery:
CR4012 to CR6022: 2 weeks for pilot bore products, 3 weeks for processed shaft holes.
CR8018 to CR12022: Both pilot bore and bore-machined products can be delivered in 4 weeks, and large sizes can also be delivered in a Quick delivery.

Nylon chain coupling standard type
Model number CN□□□
This is an economy type with a resin chain such as polyacetal wound around the sprocket.
- ・Can be installed with a short center distance:
The structure is simply two sprockets connected by a nylon chain, so even if the distance between the two shafts is short,
The entire device can be made compact. - - Easy to put on and take off as it is a wraparound type:
Easy to assemble by wrapping the nylon chain around the sprocket and inserting the joint pin.
In addition, when performing maintenance on the equipment, it is possible to disconnect the drive and driven machines without moving them. - ・Torque can be increased without changing the overall length:
By increasing the number of teeth on the sprocket, the transmission torque of the coupling can be increased,
The coupling size can be increased without changing the center distance.
Applicable shaft diameter
10Φmm～Φ55mm
Torque Range
6.9～255N・m
