Spherical Roller Bearings
222CA, 223CA, 230CA, 232CA, 239CC, 240CA, 241CA series with W33 oil groove and lubrication groove. Self-aligning design for heavy radial and axial loads in mining and industrial equipment.
Cage Types & W33 Designation
CA — Brass Machined Cage
One-piece solid brass cage, machined and guided on the inner or outer ring. Higher load capacity, better heat dissipation, suitable for high speed and high vibration applications. Recommended for crushers, vibrating screens and heavy machinery.
CC — Steel Stamped Cage
Two-piece pressed steel cage, roller-guided. Cost-effective option for standard industrial applications. Good for conveyors, pumps, fans and general machinery where loads are moderate and speeds are standard.
W33 — Oil Groove & Holes
Lubrication groove and 3 oil holes in the outer ring circumference. Allows grease to be pumped directly into the bearing without disassembly. Standard on most spherical roller bearings for mining and industrial use.

Frequently Asked Questions
What is the difference between CA and CC cage types?▾
CA = Brass machined cage (high load, high temperature, high speed). CC = Steel stamped cage (standard applications, cost-effective). For mining crushers and vibrating screens we recommend CA brass cage for better durability under shock loads and vibration. W33 = Lubrication groove and 3 oil holes in outer ring.
What radial internal clearance should I choose?▾
Standard clearance is CN (normal). For vibrating screens and crushers we recommend C3 (greater than normal) or C4 (greater than C3) clearance to accommodate thermal expansion and interference fits on rotating shafts. C4 is standard for vibrating screen applications.
Do all spherical roller bearings come with W33 oil groove?▾
W33 indicates a lubrication groove and 3 oil holes in the outer ring, which allows re-greasing without disassembly. Most of our spherical roller bearings for mining applications come with W33 as standard. We can also supply without W33 (plain outer ring) on request.
Can I order mixed sizes of spherical roller bearings?▾
Yes, mixed models and sizes are accepted. We understand that maintenance and repair orders often need multiple different bearing types. Contact us with your list and we will quote accordingly.
