20210-K-M-C3 Spherical Roller Bearing 50×90×20mm 1:12 Taper Bore Brass Cage C3 Clearance For Crusher Conveyor Machinery GQZ
- 20210-K-M-C3 is single row barrel spherical roller bearing with dimensions 50×90×20mm. It adopts 1:12 tapered inner bore, which can be installed with H210 adapter sleeve onto smooth shaft. Equipped with solid machined brass cage for stable medium-speed heavy-duty operation. Spherical outer raceway provides excellent self-aligning capacity to compensate shaft installation misalignment. Open structure supports grease or circulating oil lubriion, C3 enlarged clearance is suitable for working conditions with temperature rise. It can withstand heavy radial loads and moderate bidirectional axial loads, widely used in mining crushers, bulk conveyors and general heavy industrial equipment.
