The listed dimensions describe the cylindrical-bore configuration. If the existing bearing includes K or another bore suffix, confirm the bore and mounting arrangement rather than dropping the suffix from the enquiry.
What CA and W33 Tell the Buyer
The CA construction uses two rows of spherical rollers and a machined brass cage in this catalogue designation. The common spherical outer-ring raceway accommodates misalignment within the limits of the bearing and installation. The permissible angle still depends on the arrangement; this page does not assign a universal value.
W33 identifies the outer-ring lubrication groove and holes. Check that the housing lubricant supply reaches those features and that the specified lubricant suits the load, speed and temperature. W33 does not by itself specify the lubricant or the relubrication interval.
Check the Installation Envelope, Not Just the 200 mm Bore
For comparison, the 24040 CA/W33 bearing also has a 200 mm bore but measures 310 mm outside diameter by 109 mm width. The 22340 needs a 420 mm outside envelope and 138 mm width. They are not direct replacements simply because they fit the same nominal shaft diameter.
For maintenance procurement, confirm the housing seat, shaft and housing shoulders, fillet radii and available axial space. For a new design, provide load direction and magnitude, speed, fit and thermal conditions for a separate selection review.
22340 Bearing Procurement Checklist
- Full designation: CA/W33 and any clearance, accuracy or additional suffix.
- Required quantity and whether the order is for a new assembly or replacement.
- Operating loads, speed, lubrication and relevant drawing.
- Inspection documents, marking and packaging requirements, and delivery destination.
Internal clearance and precision are order requirements; neither is inferred from CA/W33. Request load ratings and speed limits for the offered ZQM configuration rather than transferring figures from another brand.
Questions About 22340 CA/W33
Is CA/W33 the same as C3?
No. CA describes the construction and cage designation here, while W33 describes lubrication features. C3 is an internal-clearance class and must be specified separately when required.
Can a CC version be substituted?
Matching principal dimensions do not settle the substitution. Review the cage design, internal geometry, ratings and application requirements before approving an alternative.
What should I send for a quotation?
Send the full bearing marking, quantity, destination and technical requirements. A drawing or clear marking photograph is useful when the existing configuration is uncertain.

22340CA/W33 Sourcing: China Supply and Flexible Orders
ZQM Bearings supports overseas distributors, importers, machinery manufacturers and industrial end users. Discuss small quantities, mixed-model purchase lists and wholesale or bulk-order requirements. Our manufacturing resources in Wafangdian, export coordination in Ningbo and Shanghai warehousing support order planning; actual availability, MOQ and lead time are confirmed by enquiry.
Brand Alternatives and OEM Review
For an alternative or replacement requirement, send the complete original brand designation, suffixes and drawing. Matching dimensions alone do not confirm interchangeability. Cage, clearance, precision, internal design and operating conditions require review. OEM and custom-bearing requests are assessed against the supplied technical requirements.
