Rollvis BU support bearing units are engineered for the high-speed, high-acceleration duty of planetary roller screws: fixed-end BUC units use two deep-groove ball bearings for bidirectional axial loads, while floating-end BUM units combine a cylindrical roller with a deep-groove ball bearing to compensate thermal growth. Bore sizes 8-32 mm, load ratings up to 100 kN, grease nipples standard with optional oil ports, four-screw mounting, keyway and adjustable radial/axial play options - the matching support hardware for servo cylinders and humanoid linear actuators.
