Roller chain coupling

Model No. 　Main unit ：CR□□□□H　Housing ：CR□□□□K

Go to Model No. Selection

Flexible couplings consisting of two sprockets provided with robust two-strand chains specially designed for couplings.

  • ・Constructed of two-strand chains and two sprockets. Can be connected and separated without moving the equipment by winding the chains over and removing them from the sprockets.
  • ・Excellent Durability ：
    The coupling provides outstanding durability with the torque distributed to the strong roller chains and surface-hardened sprocket teeth.
  • ・Absorption of Large Misalignment ：
    The clearance between the components absorbs large misalignment of both shafts.
  • ・Wide variety of products available. ：
    A total of 24 models, including 15 models compliant with JIS standards and 9 other models, are standardized.
  • ・Housing ：
    Prevent lubricant spatter and dust infiltration, ensuring longer life of couplings. (Selling seperately )

Nylon Chain Coupling 　Standard type

Model No. 　CN□□□

Go to Model No. Selection

Economical, flexible couplings consisting of sprockets and typical engineering plastic chains made of polyacetal.

  • ・Compatible with short inter-shaft distance ：
    This coupling consists of two sprockets that are connected with nylon chains, so it can be installed even when the distance between the shafts is short, allowing for more compact design of your equipment.
  • ・Easy to install and remove ：
    Can be installed by simply winding the nylon chains over the sprockets, and inserting a joint pin. Also, you can cut the edge without moving the drive unit and driven unit for maintenance of your equipment.
  • ・Higher torque available with no length change ：
    The coupling transmissible torque can be raised by increasing the number of sprocket teeth. Without changing the inter-shaft distance of your equipment, you can increase the coupling size.
Applicable shaft diameter

10Φmm～Φ55mm

Torque range

6.9～255N・m
