Tsubaki Chain Co., Ltd. CR5108 Roller Chain Kit

Description:

The Tsubaki CR5108 Roller Chain Kit is used in industrial power transmission systems to connect rotating shafts while accommodating shaft misalignment and transmitting torque through a flexible roller chain coupling. Commonly installed in conveyor systems, pumps, compressors, mixers, packaging machinery, and material handling equipment requiring flexible shaft coupling assemblies. Maintenance teams and system integrators use this coupling kit for repair, retrofit, expansion, or replacement to restore reliable torque transmission and simplify equipment maintenance.

Applications:

The Tsubaki CR5108 roller chain kit includes two CR5018-J coupling sprockets with a 32 mm finished bore and a CR5018 duplex roller chain to create a complete flexible coupling assembly. The wrap-around chain design allows installation or removal without repositioning connected equipment, while accommodating angular, parallel, and axial shaft misalignment. It is widely used in conveyors, pumps, compressors, fans, mixers, packaging equipment, and industrial drive systems where dependable torque transmission and easy servicing are required.
