Polyurethane tension roller

Polyurethane tension rollers are industrial roller components based on a metallic roller core, with the surface coated in polyurethane elastomers. They are specifically designed for tension systems on heavy-duty production lines such as steel and aluminum strips. Their core function is to tighten strip materials through high friction coefficients (≥0.8) and high resilience (rebound rate ≥95%), precisely controlling tension and preventing slipping or scratching on the surface. This ensures timely response and even winding tension during material speed changes. Key features include:

‌       1. Superior Abrasion Resistance: Polyurethane layer has 5-10 times the abrasion resistance of rubber, withstanding high linear speeds and heavy load impacts.

       2. Robust Bonding Structure: Utilizes composite bonded technology, bonding strength ≥ 12MPa, to prevent delamination and failure during high-speed operation.

       3. Industrial Compatibility: Compatible with cold rolling and galvanized lines, operating temperature range of -40℃ to 120℃, resistant to oil stains and acidic/alkaline corrosion. This roller is a core component ensuring continuous operation efficiency and product precision on high-end production lines.
