Tsubaki CT-ETS80 Chain Tensioner RS80-1 Chain 16.25mm Pitch

Description:

The Tsubaki CT-ETS80 Chain Tensioner is used in industrial roller chain drive systems to maintain proper chain tension and ensure smooth, reliable power transmission. Commonly installed in conveyor systems, packaging machinery, material handling equipment, production lines, and automated manufacturing systems utilizing ANSI RS80-1 roller chains. Maintenance teams and system integrators use this chain tensioner for repair, retrofit, expansion, or replacement to reduce chain slack, minimize vibration, and extend chain and sprocket service life.

Applications:

The Tsubaki CT-ETS80 is a direct-acting (ETS type) chain tensioner with an integrated idler sprocket designed for ANSI RS80-1 roller chain applications. Its spring-loaded aluminum body automatically compensates for chain elongation caused by wear, helping maintain proper chain engagement and reduce noise. It is widely used in conveyors, packaging equipment, food processing machinery, material handling systems, and industrial automation equipment where continuous, low-maintenance chain operation is required.
