This spindle bearing supports pure rolling contact at a 15° angle, transmitting combined radial and axial loads through its angular contact design. Bore diameter is 17.0 mm, outside diameter 35.0 mm, width 10.0 mm, and net mass 0.04 kg. The cage is designated T, and the bearing is supplied without sealing, leaving the raceway open for direct lubricant application. Tolerances are restricted to the P4S accuracy class, giving tighter control over running accuracy than standard tolerance bearings. Being adjusted and supplied in pairs or sets, this bearing is intended for mounting configurations where axial preload and mutual positioning between bearings are set at assembly rather than left to standard clearance. The absence of sealing means external sealing arrangements and lubrication feed must be provided by the surrounding housing design. The P4S tolerance class and 15° contact angle make it suited to applications requiring precise shaft guidance under combined loading, where radial and axial stiffness must be controlled through the paired arrangement.
