23052EMB 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.
FAQ
Is 23052EMB available, and what is the MOQ?
RAYSDE supplies it directly from ISO 9001:2015 certified partner factories, with both stock and made-to-order options. Standard-part MOQ is tiered by bore (≤50mm:500 pcs / 51–100mm:100 pcs / 101–300mm:20 pcs / >300mm:4 pcs); non-standard customization is negotiated per drawing. Submit an inquiry to get a formal quote and lead time.
What are the technical specifications (dimensions/load/speed) of RAYSDE 23052EMB?
23052EMB Spherical Roller Bearing key parameters: bore d=260.0mm, outer D=400.0mm, width B=104.0mm, dynamic load Cr=1820.0kN. For the full dimension table, load/speed data and CAD drawings, contact RAYSDE.
Which industries and equipment is the Spherical Roller Bearing suitable for?
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 23052EMB versus imported brands?
As a supplier partnered with ISO 9001:2015 certified factories, RAYSDE offers 23052EMB at a competitive ex-works price with shorter lead times than same-spec imported brands, plus non-standard customization and OEM support; ISO 9001:2015 certified and 3.1 material certificate available.
Can engineering drawings and material certificates for 23052EMB be provided?
High-precision CAD/DXF/PDF engineering drawings for 23052EMB and a 3.1 material certificate for GCr15 bearing steel are available — contact RAYSDE to obtain them.
23052EMB 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.
23052EMB 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.
