The SKF deep groove ball bearing is an essential component for supporting radial and axial loads in industrial machinery. Its single-row ball design and deep raceway grooves allow high speeds and smooth operation. The suffixes RS1 and 2RS1 indicate sealing on one side or both, protecting against contaminants and retaining lubricant. It is used in electric motors, pumps, fans, and transmissions. MR Accesorios Industriales sells this brand to provide reliable solutions.
The designation of the 60 series follows a clear system: the base number indicates the size, and the suffixes provide key information. For example, 6006-2RS1 corresponds to a bearing of the 60 series with rubber seals on both sides, while 6006-RS1 has a seal on only one side. The suffix RS1 indicates a contact seal, which offers greater protection against dust and moisture. These codes allow you to quickly identify the configuration. When choosing, consider whether you need single or double sealing depending on the environment.
These bearings are used in a wide variety of industries in Argentina. You will find them in general-purpose electric motors, centrifugal pumps, fans, compressors, conveyor belts, and machine tools. Their ability to support moderate radial and axial loads makes them versatile. In the food sector, where cleanliness is critical, RS1 seals prevent the entry of liquids and particles. They are also common in power transmission equipment and agricultural applications. Their reliability reduces maintenance downtime.
To select correctly, take into account the load, speed, and environmental conditions. If there is exposure to dust or water, choose the version with 2RS1 sealing. Check the alignment between shaft and housing to avoid additional stresses. Lubrication comes from the factory in these sealed bearings, so no subsequent maintenance is required. When mounting, apply a uniform force on the ring that is fixed, never through the balls. Proper fit and prior cleaning ensure a long service life.
Regarding equivalences, SKF deep groove ball bearings are interchangeable with those of other recognized brands that follow the same standardized dimensions. The suffixes may vary: for example, other manufacturers use 2RS or DDU for double sealing. Always check the complete code and tolerances. At MR Accesorios Industriales we advise you to find the right replacement without compromising performance. We work with the standard designations of each manufacturer.

Frequently Asked Questions
- What are the dimensions of the SKF 623-RS1 bearing?
- The SKF 623-RS1 bearing has a 3 mm bore, a 10 mm outside diameter and a 4 mm width (3 x 10 x 4 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 623.
- What does the suffix 2RS1 mean on an SKF bearing?
- The suffix 2RS1 indicates that the bearing has rubber contact seals on both sides. This provides an effective barrier against dust, water, and other contaminants, and retains the lubricant for life. It is ideal for dirty or humid environments.
- What is the difference between RS1 and 2RS1?
- RS1 has a single rubber seal on one side, while 2RS1 has seals on both sides. The double-sealed version offers greater protection, but may have a slight reduction in limiting speed. Choose according to working conditions.
- How do I know which bearing I need for my application?
- You need to know the shaft and housing dimensions, radial and axial loads, and environmental conditions. With that data, we can recommend the appropriate code. If you have the old bearing, give us the reference and we will identify it.
