The NSK R ZZS series deep groove ball bearing is a single row bearing with inch dimensions, designed to carry moderate radial and axial loads in both directions. Its compact, versatile design makes it suitable for equipment where space is limited and smooth, precise rotation is required. It is available in Inch Series sizes and is identified by its part number, which combines the model number with the ZZS suffixes. MR Accesorios Industriales quotes it for you on WhatsApp.

The R ZZS series designation reads as follows: the letter R indicates that it is a bearing from the Inch Series, with inch dimensions. The number that follows, as in R 2-6, R 133, R 155 or R 156, identifies the particular size within that series. The ZZS suffixes indicate that the bearing has two metal shield plates (ZZ) and a standard design (S). These shields prevent the entry of contaminants and retain lubrication, which extends service life in dusty or dirty environments.

In Argentine industry, these bearings are used in a wide variety of applications: from small electric motors and fans to centrifugal pumps, compressors, machine tools and power transmission equipment. They are also found in the food, textile and automotive sectors, where a reliable, low-maintenance bearing is required. Their ability to run at moderate and high speeds makes them common in continuously operating equipment.

To select the right bearing, take into account the radial and axial load it must carry, the rotation speed and the environmental conditions. The R ZZS series comes with shield plates, which makes it suitable for environments with dust or moderate humidity. If the equipment operates submerged or with liquids, additional sealing may be required. Mounting must be done with suitable tools, avoiding direct blows on the balls and raceway. Factory lubrication is usually sufficient for the entire service life in normal applications, but under severe conditions relubrication may be necessary.

As for equivalents, NSK R ZZS series bearings can be interchanged with those of other brands that follow the same nomenclature and inch dimensions, such as SKF, FAG or NTN, as long as the bore, outside diameter and width match. It is important to verify the type of protection and the precision class, since these can vary between manufacturers. If you have any doubts, ask us with the original part number and we will tell you the compatible alternative.
