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 backed by more than 80 years in the Argentine industrial market.

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 an official brand, and can advise you on interchangeability with other brands it also distributes.
