Decoding SKF 23184 CKJ/W33
- 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/W33Suffix
- 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.
Description

For equipment where shaft deflection or mounting misalignment is a fact of life, SKF spherical roller bearings provide a self-aligning, two-row solution that handles high radial loads and axial loads in both directions. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America, helping you pin down the exact part number for the job.
The part number tells you a lot once you know how to read it. Take 23184 CKJ/W33: the numeric portion points to the dimension series, CKJ signals a stamped steel cage with a tapered bore, and W33 means the outer ring carries a lubrication groove and holes. Other suffixes can show up from item to item, so it pays to confirm the full designation before you order.
You will find these bearings in cement, mining, steel, paper and material handling operations. They turn up in conveyor belts, mills, crushers, screens, heavy fans and paper machines, where loads are heavy and perfect alignment is not always achievable. The self-aligning design suits long shafts that flex under load.
Selection comes down to radial and axial load, rotational speed and lubrication method. A tapered bore calls for the right adapter sleeve and an internal clearance set to specification. Sealing depends on the environment; dusty or wet conditions call for effective seals. Lubrication should follow the manufacturer's specification and be renewed on your maintenance schedule. Getting alignment right at installation prevents premature stress.
On interchangeability, every manufacturer uses its own suffixes for similar features. A spherical roller bearing from another brand can stand in for this SKF unit when the main dimensions, bore type and design line up. There is no universal code cross-reference, so always check the complete designation and ask if anything is unclear. MR Industrial Accessories can advise on equivalents without compromising performance.
If you already have the bearing part number, send it by WhatsApp or email and we will get your quote back to you promptly. If the designation is uncertain, tell us the equipment it runs in and the shaft dimensions, and our team will help identify it. We also suggest equivalents and assist with selection.

Frequently asked questions
- SKF 23184 CKJ/W33 bearing: what are its dimensions?
- SKF 23184 CKJ/W33 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 mean on a spherical roller bearing?
- W33 indicates that the outer ring has a lubrication groove and three holes. This makes relubrication more efficient, particularly in high-load or contaminated applications. It does not affect the external dimensions or load capacity.
- Can I replace an SKF bearing with one from another brand?
- Yes, provided the main dimensions, bore type and design match. Suffixes can differ between manufacturers, so verify the complete designation and check with us to confirm compatibility before you buy.
- How is a bearing with a tapered bore mounted?
- It is mounted on a tapered shaft or with an adapter sleeve. Controlling the residual internal clearance after tightening is critical, because over-tightening shortens service life. Follow the manufacturer's instructions and use the correct tools to avoid damage.
