Decoding SKF 23184 CKJ/HA3C4W33
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 84Bore
- Bore 420 mm (84 × 5).
- CKJ/HA3C4W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23184 is the standard ISO basic designation, which sets the bearing type, series and bore.

For machinery that must keep running despite shaft deflection, heavy loads, or mounting inaccuracies, SKF spherical roller bearings provide a dependable solution. These bearings feature two rows of rollers and a self-aligning design, allowing them to accommodate misalignment while carrying high radial and axial loads in both directions. MR supplies SKF spherical roller bearings to customers across the United States, Canada, Mexico, and South America, with technical support to help you select the right designation for your equipment.
A typical SKF spherical roller bearing designation includes a basic number and suffixes that specify design features. For instance, in 23184 CKJ/HA3C4W33, the numeric prefix identifies the series and size. The suffix CKJ denotes a stamped steel cage with surface treatment, HA3 indicates a special high-temperature heat treatment, C4 specifies a radial internal clearance greater than normal, and W33 means the outer ring has a lubrication groove and holes. Understanding each suffix is critical when requesting a quote or planning a replacement.
These bearings are common in equipment subject to heavy loads and misalignment, such as conveyors, mills, pumps, gearboxes, vibrating screens, and earthmoving machinery. Their self-aligning capability compensates for shaft deflection without sacrificing load capacity, which helps reduce wear and extend service life. Industries including mining, cement, food processing, paper, and steel rely on this bearing type for dependable operation.
When selecting a spherical roller bearing, consider the radial and axial loads, speed, operating temperature, and lubrication method. A C4 clearance is often chosen for interference fits or significant thermal gradients, while the W33 groove allows in-service relubrication. Proper mounting practices, including checking initial alignment and using appropriate tools, are essential to avoid damaging the rollers. Adequate lubrication and sealing also play a key role in bearing longevity.
If you are replacing an existing bearing, do not rely solely on the basic number. Equivalent bearings from different brands may share main dimensions but differ in cage design, clearance, or heat treatment. Always compare all suffixes and confirm that operating conditions are matched. When in doubt, provide the complete code engraved on the original bearing for accurate identification.

Frequently asked questions
- SKF 23184 CKJ/HA3C4W33 bearing: what are its dimensions?
- SKF 23184 CKJ/HA3C4W33 measures 420 mm across the bore and 700 mm across the outside diameter; its width is 224 mm (420 x 700 x 224 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23184.
- What does the W33 suffix indicate on a spherical roller bearing?
- W33 means the outer ring has a groove and three lubrication holes, enabling relubrication while the bearing is in service. This is useful for equipment that is hard to access or has long maintenance intervals.
- When should I choose a C4 radial clearance instead of normal clearance?
- C4 clearance is suitable when the bearing operates with interference fits on the shaft or housing, or when there are significant temperature differences between the inner and outer rings. The extra clearance prevents preloading and premature failure.
- How do I request a quote for an SKF bearing with special suffixes?
- Send the complete bearing code, including all suffixes, via WhatsApp or email. If you don't have the code handy, a photo of the engraved designation will help us identify the exact variant and provide an accurate quote.
