This spindle bearing is built with a 15° contact angle for combined radial and axial loading under high-speed rotation. Bore diameter is 50.0 mm, outside diameter 80.0 mm, width 16.0 mm, with a net mass of 0.279 kg. The limiting speed reaches 38000 1/min, and the bearing uses a T cage with 2RSD lip seals on both sides, working as non-contact seals to minimize friction. Supplied adjusted, in pairs or sets, this spindle bearing works to restricted tolerances (P4S), suiting applications requiring precise running accuracy and consistent preload at sustained high rotational speeds. The non-contact lip seals limit heat generation while still restricting contaminant ingress, and the C cage design supports stable lubricant distribution during continuous high-speed operation.
