The SKF deep groove ball bearing of the 60 series with RSH seal and C3 internal clearance is a medium-section component widely used in applications requiring low maintenance and high reliability. Its single-row design supports moderate radial and axial loads in both directions, and the contact seal protects against the entry of contaminants while retaining the lubricant. It is a common choice in electric motors, pumps, fans and transmission equipment.
The designation of these bearings follows a clear scheme. The basic number identifies the size and the dimension series. The suffix 2RSH indicates contact seal on both sides, while RSH indicates seal on one side only. The slash followed by C3 or C4 specifies the internal radial clearance: C3 is greater than standard and C4 is even looser. For example, 6003-2RSH/C3 is a bearing sealed on both sides with C3 clearance, and 6005-2RSH/C4 has C4 clearance for more demanding conditions.
These bearings are used in a wide variety of industrial equipment in Argentina. They are common in low and medium power electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. Their ability to withstand moderate speeds and combined loads makes them suitable for belt drives, gearboxes and applications where radial space is limited. They are also found in agricultural and process equipment, where protection against dust and moisture is important.
To select correctly, take into account the load, speed and environmental conditions. The RSH seal offers good lubricant retention and contaminant exclusion, but generates more friction than a metal shield. C3 or C4 clearance is advisable when there are interference fits, thermal gradients or high speeds, as it compensates for expansion. During assembly, ensure precise alignment between shaft and housing, and avoid hitting the seals. Lifetime lubrication in sealed versions simplifies maintenance.
Regarding equivalences, deep groove ball bearings with seal and increased clearance from different brands are usually interchangeable if dimensions and specifications match. However, not all manufacturers use the same suffixes: what SKF calls RSH, others identify as 2RS, RS1 or similar. Always verify the complete code and tolerances before replacing. MR Accesorios Industriales sells SKF, and can advise you on interchangeability without compromising performance.

Frequently Asked Questions
- What are the dimensions of the SKF 6203-2RSH/C3 bearing?
- The SKF 6203-2RSH/C3 bearing has a 17 mm bore, a 40 mm outside diameter and a 12 mm width (17 x 40 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6203.
- What does the RSH suffix mean on an SKF bearing?
- RSH indicates a nitrile contact seal on one side of the bearing. The 2RSH variant has seals on both sides. These seals retain the lubricant and block contaminants such as dust and moisture, although they generate more friction than metal shields.
- When is it advisable to choose C3 or C4 clearance?
- C3 or C4 clearance is recommended when the bearing operates with interference fits, high speeds or thermal differences between shaft and housing. A larger clearance compensates for expansion and prevents excessive preloads that could reduce service life.
- How do I request a quote for these bearings?
