OVR Polyethylene Tensioning Sliding Blocks
OVR (sliding blocks) are part of the tensioner for tensioning of chains during operation.
They consist of a sliding segment made of special highly resistant and abrasion-resistant plastic and a fastening screw. It is attached to the lever of the universal tensioner with a screw.
It is a universal flexible element that can simultaneously perform the functions of suspension, guidance, tensioning and damping.

- Simple construction, easy installation
- They extend service life and reduce wear
- They reduce vibration and transmission noise
- Operating temperatures from −40 °C to +80 °C (operating temperature of a sliding block ≤ 70 °C)
- Maintenance-free design
- Operating speed ≤ 20 m/min
Sliding Blocks Material
Polyethylene sliding block with high molecular weight.
