The SKF NR/C series deep groove ball bearing is a single-row bearing with a retaining ring (NR) and C3 internal clearance. It is used in applications requiring axial location in the housing and tolerance to high temperatures. MR Accesorios Industriales supplies this line.
The designation of these bearings combines the series number with the suffixes NR and C3. For example, 6205 NR/C3 indicates a bearing of series 62, with a retaining ring and C3 internal radial clearance. Series 60 is a lighter section than 62, and 63 is heavier. The NR suffix means that the bearing includes a retaining ring, which allows it to be axially located in the housing without the need for covers or other elements. The C3 suffix indicates a greater-than-standard internal clearance, suitable for applications with high operating temperatures or interference fits.
These bearings are used in a wide variety of industrial equipment in Argentina: electric motors, centrifugal pumps, fans, gearboxes, conveyors and agricultural machinery, among others. The presence of the retaining ring simplifies the housing design, since it avoids the use of shoulders or covers for axial positioning. They are common in applications where the bearing must support moderate radial and axial loads, and where simple and reliable location is required.
To correctly select an NR/C3 bearing, take into account the radial and axial load it will support, the rotational speed and the environmental conditions. C3 clearance is recommended when temperature differences between shaft and housing are expected, or when the fit is an interference fit. Sealing will depend on contamination: the more dirt, the more advisable a bearing with seals or shields. Lubrication must be suitable for the temperature and speed; in many cases, factory grease is sufficient, but in critical applications periodic relubrication is recommended. Alignment between shaft and housing is essential to avoid additional loads.
Regarding equivalences, deep groove ball bearings with retaining ring and C3 clearance from different brands are interchangeable if the main dimensions and suffix type match. However, not all manufacturers use the same nomenclature for the retaining ring or clearance. Therefore, it is always advisable to verify the complete part number and tolerances before replacing one bearing with another from a different brand. MR Accesorios Industriales supplies SKF as a brand, and can advise you on interchangeability with other brands it also distributes.

Frequently Asked Questions
- What are the dimensions of the SKF 6207 NR/C3 bearing?
- The SKF 6207 NR/C3 bearing has a 35 mm bore, a 72 mm outside diameter and a 17 mm width (35 x 72 x 17 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6207.
- What does the NR suffix mean in an SKF bearing?
- NR indicates that the bearing includes a retaining ring (also called snap ring) on the outer ring. This ring allows the bearing to be axially located in the housing, simplifying the design and avoiding the use of covers or shoulders.
- When is it better to use a bearing with C3 clearance?
- C3 clearance is recommended when the bearing will operate at high temperatures, since thermal expansion reduces internal clearance. Also when the fit on the shaft or housing is an interference fit, or when greater tolerance to slight misalignment is required.
- Can I replace an SKF NR/C3 bearing with one from another brand?
- Yes, as long as the main dimensions (bore, outer diameter and width) and the suffix type match. However, verify the complete part number and tolerances, because each manufacturer may use different nomenclatures for the retaining ring or internal clearance.
