Caged ceramic pulley is applicable for wire jump preventing during winding.The middle ceramic roller is made by precise polishing and matched with high-speed bearing so that jump during winding can be minimized to ensure the tension stability.

Product characteristics: high wear coefficient, low friction coefficient.

Technical parameters: density 4g/cm3, bending strength 70Mpa, apparent porosity 0%, surface roughness ≤ 0.1um. 

Product introduction: Anti-jumper is used for enameled wire to change direction drastically and for appropriate amount of guidance and to prevent jumping during winding. It has a high speed bearing inside the ring, so that the sliding distance between the enameled wire and the ring is less than 0.20mm, which protects the integrity of the enamel film and ensures that the jump of the enameled wire is within a small range and maintains the stability of the tension.
