This spindle bearing supports precise shaft positioning at a contact angle of 15°, with a bore diameter of 90.0 mm, outside diameter of 140.0 mm, and width of 24.0 mm. Net mass is 1.198 kg, and the limiting speed reaches 22000.0 1/min. The bearing is designed with a T-type cage and has no sealing, matching the C-series design with restricted tolerances for adjusted mounting. Suited for high-speed rotational applications, this bearing operates individually or in matched pairs/sets, allowing for precise axial and radial positioning under demanding speed conditions. The restricted tolerances (P4S) and lack of sealing indicate it is intended for controlled environments where external contamination is managed separately, relying on precise fits and consistent lubrication to maintain performance at high rotational speeds.
