The SKF deep groove ball bearing of the ZNRJ series is a single-row bearing with a sheet metal cage, metallic shields and a locating ring with a shoulder. It is used to withstand moderate radial and axial loads in equipment that needs simple axial location and effective sealing against dust and moisture. MR Accesorios Industriales supplies this line as a brand for plants, workshops and industrial maintenance in Argentina.

The ZNRJ series designation is read in parts: the Z indicates metallic shields on both sides, the N indicates the groove for the locating ring and the R the presence of that ring, while the J corresponds to the steel sheet metal cage. A specific example is the 6308-2ZNRJ, where the base number defines the bearing size and the suffixes confirm the sealing and the axial locating system. Knowing this logic allows you to interpret the full part number before ordering a replacement.

This type of bearing is found in electric motors, centrifugal pumps, fans, conveyors and machine tools. In the Argentine industrial sector it is common in production lines, refrigeration equipment and transmission systems where simple axial retention and protection against contaminants are required. Its construction with a locating ring simplifies mounting in housings without a shoulder, which reduces machining and speeds up maintenance tasks.

To select it, verify that the housing has the appropriate groove for the locating ring and that the expected axial load is compatible with this design. The Z metallic shields protect against dust and splashes, but they do not replace a radial shaft seal in environments with abundant liquids. Factory lubrication is usually sufficient for standard applications; if the equipment operates at high temperature or speed, it is advisable to evaluate an alternative grease. Alignment between shaft and housing must be careful to avoid parasitic stresses.

As for equivalences, deep groove ball bearings with similar suffixes from other brands can be interchanged if the main dimensions, internal clearance and sealing type match. It is not enough for the base part number to be the same: tolerances and execution must be compared. For that, the best approach is to consult a specialist and validate the application. At MR Accesorios Industriales we can guide you if you send us the dimensions or the full part number of the original bearing.
