Description

The LWA type light wiper is designed for the ballbushings cleaning in the guide systems. The internal part is in contact with hardened or ground shafts. The external part is located the outside diameter of the bushing and the hanging is ensured by a groove (similar to a circlip for external use) where the wiper step is inserted. The field of applications has been enlarged to the pneumatic cylinders thanks to the very simple mechanical execution and the reduced overall dimensions. The highly flexible wiper lip does not interfere with the sliding of the guide system. Our polyurethane is very resistant to wear and is excellent at low temperature due to its high flexibility. Standard polyurethane 90 Shore A. Standard compound reference: B0 Remove cutting edges and flashes in the scraper housing. We recommend greasing the system.
