Snfa propose moulded bearing cages in peek 450 ca30 (poly ether ether ketone). Carbone fibres included in the peek 450 ca30 offer the design improved mechanical properties which are comparable to metallic cages. This property permits some comparisons to metallic cages for many applications. Peek 450 ca30 allows a maximum continuous temperature up to 150c. The very low density also offers a very good dynamic behaviour for the cages.
