MU1308WSP Spherical Roller Bearing
Selection Guide
The core value of a spherical roller bearing is self-alignment (typically compensating 1.5°–2.5° of angular misalignment) combined with very high radial load capacity — ideal for long shafts, heavy loads and imperfect alignment. Key points to verify: dynamic load rating Cr against your required life calculation, the internal design suffix (CA / CC / E) which defines cage type and roller profile, W33 (outer ring with lubrication groove and holes), and C3/C4 clearance. For vibrating machinery, mounting with an adapter or withdrawal sleeve greatly simplifies fitting and removal.

Which industries and equipment use the MU1308WSP Spherical Roller Bearing?
Used in steel mill rolls and continuous casters, mining crushers and vibrating screens, cement mills and rotary kilns, paper machine dryer sections, wind turbine main shafts and gearboxes, marine drives, and any heavy equipment subject to shaft deflection or misalignment.
What are the advantages of RAYSDE MU1308WSP versus imported brands?
As a supplier partnered with ISO 9001:2015 certified factories, RAYSDE offers MU1308WSP at competitive ex-works pricing with shorter lead times than comparable imported brands, plus non-standard customization and OEM support. Partner factories certified to ISO 9001:2015, with 3.1 material certificates available.
Can you provide engineering drawings and material certificates for MU1308WSP?
Yes—CAD/DXF/PDF high-precision drawings and 3.1 material certificates (GCr15 bearing steel) for MU1308WSP are available on request from RAYSDE.
MU1308WSP How much misalignment can a spherical roller bearing accommodate, and when is it mandatory?
Standard spherical roller bearings tolerate roughly 1.5°–2.5° of shaft-to-housing tilt (some series reach 3°), varying by series and size. They are mandatory when long shaft spans cause deflection, when housing bore concentricity cannot be guaranteed, or when the frame deforms during operation — as in vibrating screens, rolling mills and rotary kilns. Without self-alignment, roller end stress concentration sharply reduces service life.
MU1308WSP What do W33, C3, CA and CC mean on a spherical roller bearing?
W33 means the outer ring has an annular lubrication groove and three oil holes for circulating oil lubrication. C3/C4 means radial clearance greater than normal, common for heavy and shock loads. CA indicates a one-piece machined brass cage with symmetrical rollers; CC indicates a two-piece pressed steel cage with a higher-capacity design. Send us your load spectrum and lubrication method and we will specify the exact suffix combination.
