SKF 2RSHNR series deep groove ball bearings combine double-sided sealing with a retaining ring on the outer ring. This simplifies axial mounting in housings without a shoulder, since the ring holds the bearing in position. They are suitable for equipment requiring protection against contaminants and simple fixing, such as electric motors, pumps and light transmissions.

The designation of these bearings is interpreted as follows: the basic number (for example, 6004, 6205 or 6304) indicates the size and dimension series. The suffix 2RSH indicates that they have two rubber seals, one on each side, which retain the grease and block the entry of dust and moisture. The NR ending indicates that the outer ring has a groove and comes with a retaining ring, which allows the bearing to be fixed axially in the housing. Thus, 6004-2RSHNR is a sealed bearing with a ring, and the same applies to the other part numbers in the list.

These bearings are used in a wide variety of industrial equipment in Argentina. They appear in low and medium power electric motors, centrifugal pumps, gearboxes, fans, conveyors and agricultural machinery. The double-sided sealing makes them suitable for environments with dust, chips or splashes, provided high speeds are not required. The retaining ring is practical in split housings or housings where there is no shoulder to stop the bearing, because it simplifies the design and mounting.

To select correctly, take into account the radial and axial load it will support, the rotation speed and the environmental conditions. The 2RSH seal is already lubricated at the factory, so it needs no additional maintenance; if the equipment works at high temperatures or high speeds, evaluate other variants. During mounting, ensure careful alignment between shaft and housing, and avoid hitting the seals. The retaining ring is placed in the groove of the outer ring and rests against one face of the housing; check that the groove is clean and free of burrs.

As for equivalences, deep groove ball bearings with seals and retaining ring from different brands are usually interchangeable if the main dimensions and the type of fixing match. For example, a part number with the 2RS and NR suffixes from another brand can replace an SKF 2RSHNR, but always confirm the tolerances and internal clearance. Not all manufacturers use the same nomenclature, so it is essential to verify the complete part number and dimensions before replacing.

If you need to replace a bearing of this type, send us the part number engraved on the ring or the main dimensions (inner diameter, outer diameter and width) via WhatsApp. At MR Accesorios Industriales we help you identify the exact reference and provide a quote. We work with SKF and other brands so you can find the right solution for your equipment.
