The SKF RLS series is an inch-dimension deep groove ball bearing built for shafts measured in inches. Its single-row ball construction handles moderate radial and axial loads, making it a practical choice where precision and dependable operation matter. MR Industrial Accessories LLC supplies this brand to customers throughout the United States and Latin America, and can help you match the right bearing to your equipment.
In the RLS designation, the letters identify SKF's inch deep groove ball bearing line, while the number that follows shows the bearing size based on bore diameter in inches — for example, RLS 4-2Z or RLS 10-2Z. Suffixes tell you how the bearing is closed: -2Z means two metal shields, one per side, which hold lubricant in and keep contaminants out; -2RS means rubber seals; and no suffix means the bearing is open. Reading these codes correctly is the first step in selecting a replacement.
These bearings appear in centrifugal pumps, fans, conveyors, machine tools and agricultural equipment. They suit electric motors, gearboxes and transmission systems because they run at moderate speeds and carry combined loads. Sealed versions are often chosen in food processing, where cleanliness is critical, and they are also found in mining, oil and gas equipment and textile operations.
Selection depends on load type, rotation speed and the operating environment. Where dust or moisture is present, a -2RS sealed version is preferred over a -2Z shielded one. Protected bearings arrive pre-lubricated and need no additional maintenance. During installation, confirm that shaft and housing tolerances are correct and that the components are aligned, and press on the appropriate ring with suitable tooling rather than striking the bearing.
For equivalences, SKF RLS bearings can generally be interchanged with other brands that use the same inch designation, such as FAG, NSK or NTN. Dimensions and tolerances should still be verified, since minor differences can exist, and interchangeability is not automatic. Our team can review the specifications and advise on the best option for your application.

Frequently asked questions
- What does the -2Z suffix mean on an RLS bearing?
- It means the bearing has two metal shields, one on each side. The shields retain lubricant and block dust and dirt, which helps extend service life in contaminated environments.
- Are RLS bearings interchangeable between brands?
- In general, RLS bearings from different brands with the same inch designation can be interchanged. Always check the specific dimensions and tolerances, as differences may exist. Contact us to confirm compatibility.
- Where are RLS bearings typically used?
- They are common in pumps, fans, conveyors, machine tools, agricultural equipment and electric motors. Their ability to support moderate radial and axial loads makes them versatile across many industries.
