Chain and belt tensioners

Tensioners maintain constant chain or belt tension and automatically compensate for its elongation during operation. Correct tension reduces chain vibration and whipping, prevents the chain from jumping teeth on the sprockets and extends the life of the entire drive.

Chain and belt tensioners - automatic tensioning instead of manual adjustment

A spring tensioner replaces manual adjustment - you no longer have to move the motor or shorten the chain from time to time, and the drive runs more quietly and evenly. The system is modular: you choose a working element to suit the drive for a single arm, and you replace a worn element without removing the arm. Nickel-plated, zinc-plated and stainless steel arms also work in damp conditions and in the food industry.

Arms, tensioner sprockets, slides and pressure rollers - a modular chain and belt tensioner

Tensioner arms are pivoting arms with a built-in elastic element, plus brackets for mounting them. Tensioner sprockets are sprockets with a bearing and a bolt. Chain slides press against the chain with a sliding surface, and Pressure rollers include rollers for belts and for the back of the chain.

How to choose a chain or belt tensioner for the size of the drive

Choose the arm size according to the size of the chain or belt and the required tensioning force. Choose the working element according to the drive: a sprocket for a chain, a slide for quiet running at moderate speed, a roller for a belt. The arm version depends on the operating environment.

Frequently asked questions about chain and belt tensioners

Where should a chain tensioner be fitted?

On the slack side of the chain, as close as possible to the driving sprocket, so that the tensioner increases the wrap angle of the sprocket.

Does a tensioner sprocket fit every arm?

No. Each sprocket has a bolt matched to a specific arm - the arm designation is given in the sprocket name.

Are the tensioners available from stock?

Stock availability is shown above the product price and may vary depending on the warehouse.
