The SKF deep groove ball bearing is an essential component for supporting radial and axial loads in industrial machinery. Its single-row ball design allows high speeds and low maintenance. It is used in electric motors, pumps, fans and conveyors. At MR Accesorios Industriales we carry this official brand and advise you so you choose the right sealing and lubrication for your application.
The designation of these bearings combines letters and numbers that indicate key characteristics. For example, the suffix 2RS1 indicates rubber seals on both sides, while NTN identifies the manufacturer. The slash and the code C4 indicate an internal clearance greater than normal. In the example 6308-2RS1NTN9/C4, the number 6308 corresponds to the dimension series, and the suffixes define sealing and clearance. Knowing these codes lets you select the correct bearing for your equipment.
These bearings are used in a wide variety of industries in Argentina: from food and chemical plants to metalworking and maintenance workshops. They are common in electric motors, gearboxes, centrifugal pumps, compressors, conveyor belts and machine tools. Their ability to support combined loads and run at high speeds makes them versatile. In dusty or humid environments, choosing the right sealing is critical to extending service life.
When selecting a deep groove ball bearing, take into account the load, speed and environmental conditions. The 2RS1 sealing offers good protection against contaminants, while open or metal-shielded versions are for cleaner environments. Internal clearance, such as C4, is specified for applications with high temperatures or interference fits. Mounting must ensure alignment between shaft and housing, and lubrication must be suitable for the working temperature. Incorrect mounting shortens bearing life.
As for equivalences, deep groove ball bearings follow international dimension standards, so different brands can be interchanged if dimensions and suffixes match. However, always verify tolerances and internal clearance, as they can vary between manufacturers. Sealing and clearance codes are not universal; that is why it is important to confirm the complete designation. At MR Accesorios Industriales we can help you find the right replacement for your original bearing.

Frequently Asked Questions
- What does the suffix 2RS1 mean on an SKF bearing?
- The suffix 2RS1 indicates that the bearing has rubber seals on both sides, which provides an effective barrier against dust, dirt and moisture. This makes it suitable for contaminated environments, although it may reduce the maximum permissible speed compared with open versions.
- How do I choose between normal clearance and C4?
- C4 clearance is greater than normal and is recommended when the bearing operates at high temperatures or when there are interference fits that reduce internal clearance. If your application is standard, normal clearance is usually sufficient. Consult us to evaluate your case.
- Can I replace an SKF bearing with another brand?
- Yes, if the main dimensions and the sealing and clearance suffixes match. International standards guarantee dimensional interchangeability, but always verify tolerances and internal clearance, as they can vary between manufacturers. We help you find the correct equivalent.
