Linear ball bearing 20 mm

Rubber sealed linear ball bushings: Manufactured with rubber seals these linear ball bushings are characterised by their smooth movement, high rigidity and low friction, they are easy to maintain or replace and have a good life span in service. They consist of steel outer housings with sets of balls running around their own tracks within the low friction polyamide / steel inner raceways. Rubber seals to prevent the ingress of dust and moisture. 

Closed types - the outer raceway is solid with no relief machined so clearances are preset.

Benefits: Low friction, low maintenance, rubber seal limits moisture and dirt ingress, cost effective solution
