HRC58-60 Hardness Haul-off Rollers with Hard Chrome Plating for 5-10 Year Service Life in PP Strapping Lines

Haul-off rollers are among the components that have the most frequent contact with PP tape and suffer the greatest wear. All rollers in the haul-off units (low-speed three-roller, high-speed five-roller, high-speed three-roller) of this production line are made of high-quality alloy steel substrate, precision ground and then hard chrome-plated, achieving a final hardness of HRC58-60.

This hard chrome layer offers extremely high wear resistance, excellent corrosion resistance, and a very low coefficient of friction. It can withstand long-term abrasion from PP tape, keeping the roller surface smooth as new, thereby ensuring stable traction force, preventing product scratching, and significantly extending roller service life, dramatically reducing maintenance frequency and spare parts costs.
