Decoding SKF 23022-2RS/VT143
- 230Series
- Spherical roller bearings, 230 series. Series differ in outside diameter and width even when the bore is the same.
- 22Bore
- Bore 110 mm (22 × 5).
- 2RS/VT143Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23022 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23022-2RS/VT143 measures 110 mm across the bore and 170 mm across the outside diameter; its width is 45 mm (110 x 170 x 45 mm).

The SKF spherical roller bearing is built to handle heavy radial loads and angular misalignment between shaft and housing. Its two rows of rollers and spherical raceway let the inner ring self-align, which reduces stress on the shaft and helps extend the life of the assembly. It is common in demanding industrial equipment such as gear reducers, pumps and process machinery. MR Industrial Accessories supplies it as part of its SKF bearing line.
The part number carries the key selection details. In 23022-2RS/VT143, the digits 23022 indicate the dimension series. The 2RS suffix means contact seals on both sides, keeping lubricant in and contaminants out. The /VT143 extension identifies high-temperature grease and a specific internal clearance. Reading these codes correctly helps you match the bearing to the environment and operating conditions.
These bearings appear in cement, mining, steel, paper and food processing plants. They are used in gear reducers, conveyor belts, mills, centrifugal pumps and industrial fans. Because they tolerate misalignment, they suit mountings where perfect alignment between supports is hard to maintain or where the shaft deflects under load. They also handle vibration and moderate shocks, which supports reliability and reduces maintenance downtime.
For selection, check the radial and axial loads, rotation speed and environmental conditions. The 2RS sealing is a good fit for dusty or damp areas; open versions rely on external lubrication. During mounting, ensure proper initial alignment and use tools that do not damage rollers or raceways. Use the specified lubricant; variants such as /VT143 already contain high-temperature grease. Correct internal clearance helps prevent thermal overloads.
SKF spherical roller bearings can be interchanged with other brands that follow the same standardized dimensions. However, suffix designations differ between manufacturers, so the same sealing or lubrication feature may use different letters. When sourcing a replacement, compare the main dimensions and functional characteristics, not just the code. MR Industrial Accessories can advise you on the best option for your application.

Frequently asked questions
- SKF 23022-2RS/VT143 bearing: what are its dimensions?
- SKF 23022-2RS/VT143 measures 110 mm across the bore and 170 mm across the outside diameter; its width is 45 mm (110 x 170 x 45 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23022.
- What does the 2RS suffix mean on an SKF bearing?
- The 2RS suffix indicates contact seals on both sides. These seals retain grease and block dust, water or particles, which helps extend service life in contaminated environments where frequent relubrication is not possible.
- How do I choose between a sealed and an open bearing?
- Choose a sealed bearing for dirty or damp environments or when periodic relubrication is difficult. Choose an open bearing for high speeds or when a centralized lubrication system provides a constant oil flow. Also consider the operating temperature.
- Are SKF bearings interchangeable with other brands?
- In general, SKF spherical roller bearings follow international dimension standards, so they can be interchanged with other brands. But suffixes for sealing, clearance or lubrication may vary. Always verify dimensions and functional characteristics before replacing.
