This spindle bearing carries a 15° contact angle and is designed for precision-adjusted mounting in pairs or sets. Bore diameter is 120.0 mm, outside diameter 180.0 mm, width 28.0 mm, and net mass 2.286 kg. The bearing uses a T cage and reaches a limiting speed of 16000 1/min. Sealing is executed as 2RSD, with lip seals fitted on both sides, operating without contact against the mating surface. The non-contact seal design keeps friction low, supporting stable performance at the rated limiting speed while still restricting contamination ingress. Restricted tolerances (P4S) and the C designation indicate a defined internal clearance suited to precise, low-runout mounting, and pairing or set arrangement allows controlled preload for consistent axial and radial stiffness under the 15° contact angle geometry.
