Chain tensioner

belthydraulicspring-loaded

Product overview
Hydraulic damping tensioners provide precise belt or chain tension control for heavy-duty, dynamic applications. Designed to combine durable sealing elements with a hydraulic damping system, they ensure controlled deceleration and rapid recovery under varying loads.

Applications
Industrial power transmission, conveyors, heavy machinery and environments requiring accurate tensioning and repeatable dynamic behaviour.

Long lifetime in a heavy duty environment

• Rubber eyepieces for sealing and shock absorption
• Preassembled spring isolated from the internal hydraulic circuit
• High-performance hydraulic oil for stable behaviour over temperature ranges

High-performance asymmetric damping
High damping in the tensioning direction with fast recovery in the opposite direction, ratio up to 100:1 for controlled dynamic response.

Modular approach

• Linear tensioners: multiple length and stiffness ranges for tailored preload
• Rollers: choice of widths, diameters and rim materials (cast iron, steel, sheet metal, thermoplastics, Thermodur)
• Arms: configurable to available geometry and environmental constraints
