Tsubaki CR5018-J Roller Chain Coupling

Description:

The Tsubaki CR5018-J Roller Chain Coupling is used in industrial power transmission systems to connect two rotating shafts while accommodating shaft misalignment and transmitting torque efficiently. Commonly installed in conveyor systems, pumps, compressors, mixers, packaging machinery, and material handling equipment requiring flexible shaft coupling. Maintenance teams and system integrators use this coupling for repair, retrofit, expansion, or replacement to restore reliable torque transmission and simplify equipment maintenance.

Applications:

The Tsubaki CR5018-J roller chain coupling consists of two hardened steel sprockets connected by a duplex roller chain, providing excellent durability and the ability to absorb angular, parallel, and axial shaft misalignment. Its wrap-around chain design allows the coupling to be installed or removed without moving connected equipment, making it well suited for conveyors, fans, pumps, compressors, packaging equipment, and industrial drive systems where easy maintenance and dependable power transmission are essential.
