Decoding SKF C 4032 K30/C4
- C 40Series
- CARB roller bearings, C 40 series. Series differ in outside diameter and width even when the bore is the same.
- 32Bore
- Bore 160 mm (32 × 5).
- K30/C4Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
C 4032 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF C 4032 K30/C4 measures 160 mm across the bore and 240 mm across the outside diameter; its width is 80 mm (160 x 240 x 80 mm).

When a shaft flexes or the housing bores do not line up perfectly, a self-aligning toroidal roller bearing keeps the assembly working without giving up load capacity. SKF CARB bearings are built for exactly that situation. MR Industrial Accessories LLC supplies this line and helps maintenance and purchasing teams confirm the right designation before an order is placed.
The designation itself carries most of the selection information. Take C 4032 K30/C4: the leading C points to the toroidal roller family, 4032 is the dimension series, K30 means a tapered bore machined to a 1:30 angle, and the C4 after the slash is the radial internal clearance class. Clearance classes in this series run from C2 through C5. Reading the code this way lets you compare a bearing on a drawing or nameplate against what is actually installed.
These bearings suit equipment where deflection or mounting error is normal: mills, conveyors, paper machines, mining machinery and cranes. Because the bearing compensates internally, a separate spherical housing is not required, which keeps the surrounding design and the maintenance routine simpler.
Selection comes down to radial and axial load, operating speed and the correct internal clearance. A tapered bore calls for an adapter sleeve and lock nut, fitted so the required interference is reached. Grease or oil lubrication both work; the sealing arrangement should match the site conditions, whether that means dust, moisture or elevated temperature. Alignment is more forgiving than with a rigid bearing, though checking that the supports are parallel is still worthwhile.
Interchange with other self-aligning toroidal roller designs is possible when dimensions, tolerances and clearance agree. No universal code mapping exists between manufacturers, so the complete designation has to be verified rather than matched by a short number. MR Industrial Accessories LLC supplies SKF and can point you toward suitable alternatives for your application.

Frequently asked questions
- SKF C 4032 K30/C4 bearing: what are its dimensions?
- SKF C 4032 K30/C4 measures 160 mm across the bore and 240 mm across the outside diameter; its width is 80 mm (160 x 240 x 80 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation C 4032.
- What does the K30 suffix mean in a CARB bearing?
- The K marks a tapered bore and 30 gives the taper angle, which is 1:30. Mounting is done with a sleeve and nut to reach the required fit, and the sleeve must match that angle.
- How do I choose the right radial clearance for my application?
- Clearance follows from operating temperature, speed and fit. C3 or C4 is often used where heat builds up. Contact MR to settle on the clearance that fits your equipment and running conditions.
- Are SKF CARB bearings interchangeable with other brands?
- They can be exchanged with self-aligning toroidal roller bearings from other makers when dimensions, tolerances and clearance line up. Since there is no universal code equivalence, always verify the complete designation before replacing.
