SKF deep groove ball bearings with the ZNR suffix combine a protective shield and a retaining ring on the outer ring. The shield keeps contaminants out and prevents lubricant loss, while the ring allows the bearing to be fixed axially in the housing without the need for side covers. They are a compact solution for positions where protection and retention are required in a single component.

The designation of these bearings follows the SKF system: the basic number indicates the size and series (for example, 6203 corresponds to the 62 series, medium section). The suffixes -2Z indicate two sheet metal shields, one on each side, and NR indicates that the outer ring incorporates a groove and a retaining ring. Thus, a 6002-2ZNR is a bearing from the 60 series, with two shields and a snap ring. The ring facilitates mounting in through housings, since it acts as an axial stop.

These bearings are used in equipment where the interior must be protected from dust and moisture, while at the same time ensuring axial position. They appear in small electric motors, gearboxes, centrifugal pumps, fans, conveyors and agricultural machinery. In Argentina, they are common in the food, textile and metalworking industries and in maintenance shops that replace bearings in imported or locally manufactured equipment.

To select the correct bearing, take into account the load, speed and environment. The 2Z shield is non-contacting, so it allows higher speeds than a contacting seal, but it does not retain moisture as well. Check that the housing has the groove for the retaining ring and that the shaft meets the appropriate tolerance. Lubrication comes from the factory; if you need to relubricate, choose a version with removable shields or seals. Alignment between shaft and housing is key to avoiding parasitic loads.

As for equivalents, deep groove ball bearings with similar suffixes from other brands can be interchanged if the dimensions and type of protection match. For example, a 6203-2ZNR from SKF can be replaced by a bearing from another brand with an equivalent designation, such as 6203-2ZNR or 6203-ZZNR, depending on the manufacturer. Always confirm the dimensions and the type of retaining ring before substituting. MR Accesorios Industriales carries SKF as an official brand, and can advise you on interchangeability.
