Product summary
22312 EK: spherical roller bearing, brand SKF. Bore diameter d 60 mm, outside diameter D 130 mm, width B 46 mm. Dynamic load rating C 310 kN, static load rating C0 335 kN, limiting speed 5300 rpm, weight 3.1 kg.
Two rows of barrel-shaped rollers on the spherical raceway of the outer ring: high load capacity combined with compensation of misalignment. For heavy and shock loads at low and medium speeds.
Where it is used
Vibrating screens and sieves, belt conveyor pulleys, crushers, mills, high-power fans, long line shafts that deflect. The spherical outer raceway compensates for misalignment of supports in a welded frame that cannot be corrected by machining.
When not to use
Do not fit it instead of a deep groove ball bearing in a high-speed assembly: in the same size, a spherical roller bearing can have a limiting speed several times lower, so the assembly will overheat and push grease out through the seals. The reverse swap costs even more: if the supports are misaligned, any rigid bearing will run on the edge of the raceway and start spalling within a few hundred hours.
