When you need to lock a bearing axially without adding covers or lock nuts, the SKF NR series deep groove ball bearing is a practical choice. It is a single-row bearing with a snap ring, also called a circlip, fitted into a groove on the outer ring. That ring holds the bearing in place inside the housing and keeps the support design simple. Typical equipment includes electric motors, gearboxes, pumps and fans. MR Industrial Accessories LLC supplies this line to customers in the United States and several Latin American countries.
Reading the part number is straightforward. The NR suffix tells you that the outer ring carries the ring and its groove. For instance, 6005 NR is a 60-series bearing of medium section with that feature. Other suffixes you may see in the same family cover seals (2RS), shields (2Z) or internal clearance (C3), but this particular reference is only the NR variant. Knowing how the code is built helps you order the exact replacement.
These bearings appear in food, metalworking, chemical and plastics plants, on electric motors, gearboxes, centrifugal pumps, fans and conveyors. They also turn up in machine tools, compressors and transmission systems that need a fixed support with simple axial adjustment. Because they handle moderate radial and axial loads, they fit many general-duty positions.
Selection comes down to the radial and axial loads, the speed and the environment. The housing must have a machined groove that matches the ring; check the groove diameter and depth against the bearing standard. Grease or oil lubrication both work depending on the application, and keeping shaft and housing aligned avoids extra loads. In dusty or damp areas, consider a sealed version.
Interchange is possible with deep groove ball bearings from other makers that have a snap ring, as long as the main dimensions and ring type line up. Confirm the full part number and tolerances. For a replacement, comparing the original bearing dimensions and the operating conditions is the safest route. Nomenclature for the ring varies between brands, so it pays to verify equivalence with a specialist.

Frequently asked questions
- SKF 6216 NR bearing: what are its dimensions?
- SKF 6216 NR measures 80 mm across the bore and 140 mm across the outside diameter; its width is 26 mm (80 x 140 x 26 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6216.
- What does the NR suffix mean on an SKF bearing?
- It means the bearing has a snap ring mounted on the outer ring. That ring fixes the bearing axially in the housing, stops it from shifting and keeps the support design simple.
- Does this bearing require a special housing?
- Yes, the housing needs a machined groove that matches the snap ring. That groove provides the axial location. If it is missing, you can machine it or use another fixing method such as side covers.
- Can it be lubricated for life or does it need maintenance?
- It depends on the application and the lubrication type. Some bearings come grease-lubricated for life, while others can be relubricated. In demanding applications, set up a periodic maintenance plan.
