The SKF deep groove ball bearing with the RSNR suffix is a single row bearing with a contact seal and an integral retaining ring. The combination of both features simplifies mounting: the seal protects against contamination and the ring allows the bearing to be fixed axially in the housing without the need for additional covers or shoulders. It is used in equipment where space is limited and a compact, reliable solution is required.
The designation of this series is made up of the size number and the suffixes. The R indicates that the bearing has a retaining ring on the outer ring; the S corresponds to the contact seal on one side; the N indicates that the retaining ring is on the outer ring; and the final R indicates the seal on the opposite side. A specific example is 63/322RSNR: the base code defines the dimensions, and the suffixes confirm that the bearing is sealed on both sides and has an outer retaining ring for direct mounting in a housing.
This type of bearing is found in applications where protection against dust, chips or moisture is needed, along with simple axial fixing. It is common in electric motors, gearboxes, pumps, fans, conveyors and agricultural machinery. In Argentina, industries such as food, metallurgy, cement and mining usually choose this configuration for its ability to withstand demanding environments without requiring frequent maintenance.
To select correctly, take into account the internal clearance, the type of lubricant and the speed and load conditions. The RSNR contact seal is suitable for applications with moderate contamination, but if there are high speeds or elevated temperatures, it is advisable to evaluate other sealing options. During mounting, check the alignment between shaft and housing, and avoid striking the bearing; the retaining ring must fit into the housing groove without forcing.
SKF bearings are interchangeable with those of other recognized brands that follow the same standardized dimensions and equivalent designations. When looking for a replacement, do not rely only on the code: check the main dimensions, the type of seal and the presence of the retaining ring. At MR Accesorios Industriales we supply SKF and can advise you to find the right equivalent.

Frequently Asked Questions
- What does the RSNR suffix mean on an SKF bearing?
- The RSNR suffix indicates that the bearing has a contact seal on both sides and a retaining ring on the outer ring. This makes it suitable for mountings where protection against contaminants and axial fixing are required without additional parts.
- Is this bearing suitable for high speeds?
- Contact seals generate some friction, so for very high speeds a bearing with a non-contact seal or an open bearing may be more suitable. Always check the speed and load conditions of your application before deciding.
