Ceramic Capstans and Pulleys

Ceramic Capstans and Pulleys

Wire drawing is a high-tension, high-speed process that requires absolute durability and surface integrity. Capstans and pulleys are critical contact points in this process, guiding and tensioning wire as it is reduced in diameter. Traditional metal components quickly wear under friction and tension, leading to product inconsistencies and frequent replacements.

Ceramic capstans and pulleys from CeramForge are engineered for wire drawing and cable manufacturing applications, delivering unmatched wear resistance, thermal stability, and a smooth surface finish that protects delicate wire surfaces.
