This self-aligning ball bearing compensates for shaft misalignment through its spherical outer raceway, allowing the inner ring, balls and cage to tilt relative to the outer ring axis. Bore diameter is 90.0 mm, outside diameter 160.0 mm, and width 30.0 mm, giving the mounting envelope. The tapered bore (K, taper 1:12) allows mounting on a tapered seat or with an adapter sleeve, with fit achieved by axial displacement rather than a straight push fit. Mass is 2.48 kg. Limiting speed is rated at 4550 1/min, reference speed at 4850 1/min. The cage is designated TVH, a glass-fibre reinforced plastic cage guided on the balls. Radial internal clearance is CN (Group N), the normal clearance range, suited to standard shaft and housing fits without additional preload or clearance adjustment. The tapered bore design simplifies dismounting and allows fine adjustment of internal clearance during mounting by controlling the amount of drive-up on the taper. No sealing or shielding is integrated, so lubrication and contamination protection must be provided externally.
