KDN.ND045XP0-Thin-walled bearing-FGFA bearings

KDN.ND045XP0 Reali-Slim thin section four-point contact ball bearing

Thin-walled bearings are compact transmission components featuring an exceptionally slim cross-section. Their core advantages lie in lightweight construction and minimal space requirements, enabling stable transmission within confined installation areas. With their compact structure and flexible rotation, they are well-suited for high-speed applications and are widely utilised in robotics, medical equipment, and aerospace machinery.
