Feature | 22230CC | 22230CCK |
Bore Type | Cylindrical (straight) | Tapered (1:12) |
Mounting | Press fit or interference fit direct onto shaft | Mounted via adapter sleeve (H3030) or withdrawal sleeve (AH3030) |
Axial adjustment | Not adjustable | Radial clearance adjustable via sleeve |
Typical use | Fixed housings, standard shafts | Long shafts, stepped shafts, frequent dismounting |
If your application requires frequent bearing removal or uses a stepped shaft, specify 22230CCK with the matching adapter sleeve. Contact our technical team for sleeve selection.
The 22230CC / 22230CCK is a 150×270×73mm spherical roller bearing featuring two rows of barrel-shaped rollers and a common sphered outer ring raceway. The self-aligning geometry accommodates shaft deflection and housing misalignment up to ±1.5°, making it the standard choice for applications subject to heavy combined loads, shaft bending, and vibration.
The W33 variant includes an annular lubrication groove and three equidistant holes in the outer ring, enabling direct grease injection through the housing — critical for large, inaccessible, or continuously running installations.

Dimensional interchange is generally valid. However, internal geometry, cage design, and clearance class may differ between brands. Verify application requirements before direct substitution.
Q: What is the difference between 22230CC and 22230CCK?CC = cylindrical bore, direct shaft mounting. CCK = tapered bore (1:12 taper), mounted via adapter or withdrawal sleeve for easy installation and removal on long or stepped shafts. Both share identical outer dimensions (150×270×73mm) and load ratings.
Q: What does W33 mean?W33 denotes an annular groove plus three equally spaced radial holes in the outer ring, allowing grease to be injected directly through the housing into the bearing. Specify W33 when your housing has a matching lubrication port.
Q: What clearance class should I specify?C0 (normal) is standard. C3 is recommended for applications with significant temperature rise, interference fits, or heavy shock loads — typical for mining and cement applications. Specify at time of order as it affects lead time and price.
Q: What precision grade is available?P0 / P6 are standard for most industrial applications. P5 / P4 / P2 available on request for precision machinery.
Q: What is the lead time?Standard P0/C0/C3: typically in stock or 3–7 business days. Special grades or configurations: made-to-order — confirm lead time with our team.
Q: What documentation is available?GCr15 / AISI 52100 material certificates, dimensional inspection reports, hardness test reports (60–64 HRC), packing lists, commercial invoices, certificates of origin. SGS / BV / TÜV third-party inspection supported on request.
Q: OEM / private label available?Yes. Custom box artwork, laser-engraved part number (22230CC / 22230CCK) and logo on bearing ring, fully branded inner/outer packaging. All IP rights belong to you. MOQ and pricing on request.
Q: What is the MOQ?Minimum 1 pc accepted for sample evaluation. Volume pricing from 5 pcs. Shipping: FOB Qingdao / CIF / EXW.
