This self-aligning ball bearing has a bore diameter of 65.0 mm, outside diameter of 120.0 mm, and width of 23.0 mm, with a net mass of 1.19 kg. The tapered bore, designated K, has a taper ratio of 1:12, allowing mounting directly on a tapered shaft seat or with a sleeve, and the cage is made of glass-fibre-reinforced plastic (TVH). Radial internal clearance is C3, giving a larger clearance than standard to compensate for interference fit and operating temperature. Limiting speed is 6500 1/min, reference speed 5800 1/min. The two-row design with spherical outer raceway allows the bearing to accommodate angular misalignment and shaft deflection, making it suitable for applications where shaft or housing alignment cannot be guaranteed to close tolerances. The tapered bore simplifies mounting and dismounting and enables adjustment of internal clearance during fitting via axial displacement on the shaft. The C3 clearance class supports operation under interference fit conditions and moderate temperature rise, while the plastic cage (TVH) provides low friction and quiet running at the stated speed range. The bearing is supplied open, without integrated seals, so lubrication and sealing arrangements must be provided externally.
