This self-aligning ball bearing compensates for shaft misalignment through its spherical outer raceway, allowing the inner ring, balls and cage to pivot relative to the outer ring. The bore diameter is 80.0 mm, outside diameter 140.0 mm, and width 33.0 mm, with a tapered bore of taper 1:12 (bore type K), permitting mounting on tapered shaft seats or with an adapter sleeve. The cage is a TVH design, a glass-fibre reinforced plastic cage guided on the balls. Net mass is 1.97 kg. Limiting speed is 5300 1/min and reference speed 5400 1/min, defining the thermal and mechanical speed boundaries for continuous operation. The radial internal clearance is C3 (Group 3), wider than normal clearance, which accommodates thermal expansion and shaft deflection under load without loss of running accuracy. Combined with the self-aligning design, this clearance class suits applications where shaft bending or housing misalignment occurs during operation. Dimensional and constructional equivalents are SKF 2216EKTN9/C3, SKF 2216K/C3, and STEYR 2216EK/TG/C3.
