Decoding SKF 23996 CA/W33
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- 96Bore
- Bore 480 mm (96 × 5).
- CA/W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23996 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23996 CA/W33 measures 480 mm across the bore and 650 mm across the outside diameter; its width is 128 mm (480 x 650 x 128 mm).

For equipment that sees constant vibration, shaft deflection or heavy combined loads, SKF spherical roller bearings in the CA/W33 series are a common choice. Their two rows of rollers run inside a self-aligning outer ring, so minor mounting errors or flexing under load do not shorten service life. Maintenance teams in cement, mining, steel and paper plants rely on them for crushers, mills, conveyors and similar machinery.
Reading the part number is straightforward once you know the suffixes. The base number gives the size and dimension series. CA identifies a one-piece machined brass cage guided by the inner ring, which supports higher speeds and helps lubricant reach the rollers. W33 means the outer ring carries a lubrication groove and three holes, so relubrication can be done without pulling the bearing. A code like 23084 CA/W33 therefore tells you size, cage type and lubrication provision in one string.
These bearings handle radial and axial loads in both directions, and the self-aligning design tolerates misalignment that would quickly damage rigid bearings. That makes them suitable for jaw crushers, ball mills, vibrating screens, large gearboxes and kiln rollers, where shock, vibration and shaft deflection are normal. In such conditions, correct selection and installation matter as much as the bearing itself.
Selection depends on radial and axial load, rotational speed, shaft diameter and the environment around the housing. Use proper tools during mounting and avoid direct impacts on the rings or cage. Even though the bearing self-aligns, checking initial alignment helps. Choose seals according to dust or moisture levels, and maintain the correct internal clearance. A clean installation with the right lubrication interval supports long service life.
SKF spherical roller bearings interchange with other brands that follow the same ISO designation. CA and W33 are SKF suffixes, but other makers use similar codes for brass cages and lubrication grooves. Always confirm dimensions and tolerances before substituting. MR Industrial Accessories LLC supplies SKF bearings and can suggest equivalents when needed.

Frequently asked questions
- SKF 23996 CA/W33 bearing: what are its dimensions?
- SKF 23996 CA/W33 measures 480 mm across the bore and 650 mm across the outside diameter; its width is 128 mm (480 x 650 x 128 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23996.
- What does CA mean in an SKF spherical roller bearing?
- CA indicates a one-piece machined brass cage that is inner-ring guided. This cage type is associated with higher speed capability and improved lubricant flow compared with stamped steel cages.
- Why is the W33 suffix important?
- W33 means the outer ring has a lubrication groove and three holes. This allows relubrication without dismounting the bearing, which simplifies maintenance on equipment that is hard to access.
- How do I select the correct spherical roller bearing?
- Consider radial and axial loads, speed, shaft diameter and environmental conditions such as dust or moisture. Provide your application data and the team can help you identify the right part number.
