This spindle bearing has a bore diameter of 50.0 mm, an outside diameter of 80.0 mm and a width of 16.0 mm, with a net mass of 0.279 kg. It is built with a 25° contact angle, a T cage, and lip seals on both sides (2RSD sealing), designed for adjustment in pairs or sets and rated for a limiting speed of 34000 1/min. Manufacturing is held to restricted tolerances, corresponding to accuracy class P4S. The non-contact lip seals on both sides keep the bearing free of added friction while limiting contaminant ingress, which supports operation at the stated limiting speed. Being supplied for pairing or set arrangement with a defined 25° contact angle allows the bearing to take up combined loads with a controlled internal setting once mounted in an adjusted arrangement, matching the accuracy demands of a P4S tolerance class application.
