Standard roller chains

IRIS Standard precision roller chains are designed and manufactured to meet and exceed ISO, DIN, ANSI and BS requirements. Commonly found in a variety of industrial drive systems, IRIS chains are engineered and built for high performance even in the toughest applications, ensuring a long service life.

IRIS conveyor chains offer the user the benefits of parallel and synchronous running, extremely precise positioning, quiet running and significantly higher breaking resistance than the norm. As a result, downtime is minimised and there is a significant reduction of the operating costs.

Our standard lubrication ensures resistance to a temperature range from -5º C to +120º C: a particular lube can be applied upon request for applications with temperatures from -30 ºC to 250 ºC.


  • Many references available in stock
