Tsubaki Chain Co., Ltd. 40-RIV Roller Chain

Description:

The Tsubaki 40-RIV Roller Chain is used in industrial power transmission systems to transmit mechanical power between sprockets in ANSI No. 40 chain drive applications. Commonly installed in conveyor systems, packaging machinery, material handling equipment, agricultural machinery, and automated manufacturing equipment requiring long-length roller chain. Maintenance teams and system integrators use this roller chain for repair, retrofit, expansion, or replacement to restore reliable power transmission and minimize equipment downtime.

Applications:

The Tsubaki 40-RIV roller chain is engineered for industrial applications requiring smooth, efficient power transmission and long service life. Its riveted construction provides a durable, permanent assembly suitable for continuous-duty operation in conveyors, production machinery, food processing equipment, packaging systems, and material handling applications. Supplied on a 50-foot reel, it can be cut to custom lengths for installation or maintenance requirements.
