Product Features

The cage pulley, also known as a non-torque pulley, is used for applications involving radical direction changes and to prevent wire jumping during the winding process.

These pulleys are made from fine ceramic (Alumina Al₂O₃), with surfaces polished to an ultra-fine Ra0.2 finish.

A high-speed precision bearing is installed within the ceramic roller, reducing the sliding distance between the enamelled wire and roller to below 0.2mm. This helps protect the wire coating and maintain stable wire tension.
