Decoding SKF C 2238 K
- C 22Series
- CARB roller bearings, C 22 series. Series differ in outside diameter and width even when the bore is the same.
- 38Bore
- Bore 190 mm (38 × 5).
- KSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
C 2238 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF C 2238 K measures 190 mm across the bore and 340 mm across the outside diameter; its width is 92 mm (190 x 340 x 92 mm).

When shaft deflection or alignment errors are part of the application, SKF CARB roller bearings provide a self-aligning solution. Their toroidally profiled rollers handle combined loads and compensate for angular misalignment. MR Industrial Accessories LLC supplies this line to customers in the United States and several Latin American countries, with support to select the correct suffix.
Reading the designation helps you specify the right bearing. The letter C stands for a single row radial bearing with toroidally profiled rollers. The digits that follow, as in C 2215 K, C 2216 K or C 2220 K, form the size code for bore diameter and dimension series. A K suffix means a tapered bore, generally 1:12, for mounting on a tapered shaft or with an adapter sleeve. Other suffixes can cover cage variants, internal clearance or special heat treatment, so confirm the complete code when you request a quote.
These bearings suit equipment where supports cannot be perfectly aligned. Typical uses include mill gearboxes, cement plants, pulp and paper machines, mining equipment, industrial fans, high-flow pumps and high-load conveyors. Because they compensate for angular misalignment without losing load capacity, they work well in assemblies subject to deflection.
Selection depends on the radial and axial loads, the rotational speed and the expected misalignment. For a K-suffix tapered bore, correct fitting on the shaft or adapter sleeve matters; improper internal clearance during mounting can shorten service life. Choose lubrication based on temperature and environment: grease for general duty, oil for high-speed systems. Even with a self-aligning bearing, initial alignment helps prevent parasitic loads.
For replacements, SKF CARB bearings can be interchanged with toroidal bearings from other manufacturers that use similar designations. Internal geometry and suffix definitions are not always identical, so compare bore type, internal clearance and operating conditions, not only the size code. MR Industrial Accessories LLC can suggest an equivalent that fits your application.

Frequently asked questions
- SKF C 2238 K bearing: what are its dimensions?
- SKF C 2238 K measures 190 mm across the bore and 340 mm across the outside diameter; its width is 92 mm (190 x 340 x 92 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation C 2238.
- What does the K suffix mean on an SKF CARB bearing?
- It indicates a tapered bore, normally 1:12. This allows mounting on a tapered shaft or with an adapter sleeve, which makes it easier to adjust internal clearance.
- How is a CARB bearing different from a cylindrical roller bearing?
- CARB bearings use toroidally profiled rollers and can compensate for angular misalignment, while cylindrical roller bearings are not self-aligning. CARB bearings also accept moderate axial loads in one direction.
- How do I pick the right CARB bearing size?
- Review radial and axial load, speed, expected misalignment and the shaft and housing dimensions. The numeric code identifies the size; share your application data for a precise recommendation.
