This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets, allowing precise control of axial play through matched face grinding. Bore diameter is 10.0 mm, outside diameter 22.0 mm, width 6.0 mm, and net mass 20.0 g. The bearing uses a T cage and has no sealing, with dimensional and running accuracy held to restricted tolerances (P4S). The restricted tolerance class and paired-mounting design suit applications requiring high rotational accuracy and stiffness under combined axial and radial load, typical of the C arrangement geometry. As the bearing is unsealed, lubrication and contamination protection must be provided externally, and mounting should follow the specified pair or set configuration to maintain correct preload and contact angle.
