Audited Supplier Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads inboth directions Long
service life. We supply single row spherical roller bearings, double row spherical roller bearings.
Technical specification
Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious construction makes it self-aligning and therefore not susceptible to axial or bearing housing angle errors or shaft bending.
MB: Solid brass cage, guidance on inner ring
CA: Retaining flanges on the inner ring, guide ring centered on the inner ring, machined brass cage
CC: Flangeless inner ring, guide ring centered on the inner ring, two stamped steel cages
E: Optimized internal design for increased load carrying capacity
2RS: Contact seal, NBR, on one or both sides
K: Tapered bore, taper 1:12
K30: Tapered bore, taper 1:30
C3: Radial internal clearance greater than Normal
W33: Annular groove and three tube holes in the outer ring
