Decoding SKF 23992 CAK/W33
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- 92Bore
- Bore 460 mm (92 × 5).
- CAK/W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23992 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23992 CAK/W33 measures 460 mm across the bore and 620 mm across the outside diameter; its width is 118 mm (460 x 620 x 118 mm).

SKF CAK/W series spherical roller bearings handle heavy radial loads while compensating for shaft misalignment. The tapered bore lets you mount them on a tapered shaft or with an adapter sleeve. They are common in equipment where deflection or vibration is part of normal operation.
Reading the code helps you confirm what you are ordering. In a designation such as 23084 CAK/W33, the 23084 gives the size, CAK signals a 1:12 tapered bore and a machined brass cage, and W33 means the outer ring carries a lubrication groove and holes. Checking these suffixes before you send your inquiry avoids a wrong replacement.
These bearings appear in cement, mining, steel, paper and material handling. Typical locations include large gearboxes, mills, crushers, conveyors and continuous process lines. Because they tolerate combined loads and misalignment, they suit machinery where the shaft flexes or vibrates and where dependable operation matters.
When selecting a size, review radial and axial load, speed and how the bearing will be mounted. A tapered bore can be fitted directly on a tapered shaft or through an adapter sleeve for a precise fit. Set the internal clearance during mounting, check alignment first, and lubricate as recommended. The W33 groove lets you relubricate through the outer ring. Correct mounting practice supports bearing life.
Spherical roller bearings with a tapered bore and lubrication groove follow international standards, so you can interchange brands when dimensions and tolerances match. SKF uses the CAK/W33 designation, which is widely recognized in the field. For a replacement, confirm the code includes K for the tapered bore and W33 for lubrication, then compare the technical data.

Frequently asked questions
- SKF 23992 CAK/W33 bearing: what are its dimensions?
- SKF 23992 CAK/W33 measures 460 mm across the bore and 620 mm across the outside diameter; its width is 118 mm (460 x 620 x 118 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23992.
- What does the CAK suffix mean in an SKF bearing?
- CAK identifies a 1:12 tapered bore and a machined brass cage. The taper allows mounting on a tapered shaft or with an adapter sleeve, while the brass cage provides strength and precise roller guidance.
- What is the W33 groove for?
- W33 means the outer ring has a lubrication groove and holes. You can relubricate the bearing through the housing, which simplifies maintenance in high-load or high-speed applications.
- How do I choose the right bearing for my application?
- Check radial and axial load, speed, mounting method and operating conditions. Make sure the code includes K for tapered bore and W33 for lubrication. Share your equipment data with us and we will help you select.
