Universal Chain Tensioners

Universal chain tensioners are automatic tensioners for tensioning of chains during operation.

They consist of a lever that is flexibly mounted between two squares and attached to the base of the machine. The elastic part consists of rubber elastic segments. Tensioning pulleys of the chains or a sliding block are attached to the lever with a screw.

It is a universal flexible element that can simultaneously perform the functions of suspension, guidance, tensioning and damping.

OVR (Sliding Blocks)

Roller chain tensioner elements consisting of a sliding segment made of a special highly resistant and abrasion-resistant plastic and a screw for attaching to the lever of the universal tensioner.

ZK (Sprockets with Screw)

Roller chain tensioner elements consisting of one, two or three tensioning pulleys according to the type of chain and a screw for attaching to the lever of the universal tensioner.

SR (Idler Sprockets)

Special type of sprockets for roller chains according to DIN 8187 with pressed single-row bearing.
