Chain and belt tensioner
Cross & Morse

Cross Tensioners provide constant belt or chain tension. Their automatic tensioning action translates into improved performance and extended life for most types of fixed-centre drives. Additionally, the built-in spring mechanism acts as a buffer, absorbing momentary overloads and reducing vibration.
Tensioners are available in a number od sizes and mounting styles, ideally suited for drives on agricultural machinery, off-road vehicles, conveyors, packaging machinery, printing presses and many other industrial applications. Precision construction and high-quality materials are combined for a superior product with proven durability in the toughest environments. Tensioners can be supplied as base units for adaptation by customer, or as complete assemblies with chain sprockets/guides for roller chain applications. There are two basic designs of tensioners available: the Rotary Tensioner and the Linear Tensioner.
