This spindle bearing carries a 90.0 mm bore, 140.0 mm outside diameter and 24.0 mm width, with a net mass of 1.14 kg. It is built with a contact angle of 25° and is supplied adjusted, for mounting in pairs or sets. The cage is designated T, and the bearing is produced to restricted tolerances under the P4S accuracy class, without sealing. The 25° contact angle allows the bearing to take up combined radial and axial loads, while the restricted tolerances and P4S class give the running accuracy required for precise shaft guidance at controlled clearance. Being supplied in pairs or sets, adjusted, means the bearings are matched for correct preload when mounted together, so the internal clearance is set by the mounting arrangement rather than by an individual bearing alone. As it has no sealing, external lubrication and protection must be provided by the housing design, and grease or oil lubrication should be selected according to the operating conditions of the assembly.
