Block Tensioner Arm – OVR Sliding
The TransDrive OVR Sliding Block Tensioner Kit is a reliable, high-performance solution designed for efficient chain tensioning in a wide range of industrial applications. Constructed from high molecular density polyethylene, the tensioner block offers excellent wear resistance and low friction properties, ensuring smooth operation and extended service life. Its innovative oval-shaped profile allows for double-sided use, providing greater flexibility and a longer operational lifespan by simply rotating the block when one side becomes worn.
Engineered to perform at operating speeds of up to 20 m/min and temperatures up to 70°C, the OVR Tensioner Kit is well-suited to demanding working conditions. Available in both simplex and duplex configurations, it supports a variety of chain sizes, making it a versatile and economical choice for conveyor systems, automated machinery, and general power transmission applications.
