Brake friction ring

custom-made

Product Overview
The XW Machinery Key Lock Differential Friction Ring is a high-performance friction ring engineered for use with Key Type Differential Shafts in slitting, rewinding, converting, printing, flexible packaging, paper processing, film manufacturing, and nonwoven production lines. It provides precise differential slip control to automatically compensate for thickness variations between slit rolls, ensuring independent tension control for each roll and resulting in tighter roll formation, improved edge quality, and reduced material waste.

Precision Differential Winding Technology
The friction ring allows controlled rotational compensation between the shaft and individual winding cores. Each ring lets a core slip slightly relative to the shaft so that every roll receives appropriate winding tension even when roll diameters or material thicknesses vary. Compared with conventional solid winding shafts, differential friction ring systems provide significantly improved winding quality and tension uniformity.
