The SKF WR series deep groove ball bearing is a single-row bearing with inch dimensions, designed for shafts that do not follow the metric system. It is used in imported equipment, machine tools and transmissions where the housing and shaft are in inches. Its ball and deep groove design allows it to support moderate radial and axial loads in both directions, with low torque and good rotational speed. MR Accesorios Industriales sells this line as an official brand.

The WR series designation is read in parts: the letters WR identify the inch deep groove ball bearing series, the number that follows indicates the size within that series and the suffix Z indicates that the bearing has a shield on one side. For example, in WR 8-2Z, the 8 corresponds to the size and 2Z indicates protection on both sides. That shield prevents dust ingress and retains lubrication, but it does not seal against liquids. If the code has no suffix, the bearing is open.

These bearings appear in equipment with inch shafts: machine tools, pumps, fans, conveyors and imported transmissions. In Argentina they are found in production lines, maintenance workshops and food or chemical plants where a bearing must be replaced without modifying the shaft. Being an inch size, there is not always a direct metric equivalent, so it is advisable to verify the shaft and housing diameter before choosing.

To select the bearing, first look at the type of protection: open if the environment is clean and frequently lubricated, with one Z shield if there is dust, and with two 2Z shields if the risk of contamination is greater. The WR series is not designed for pressure washing or immersion. During mounting, work with a clean shaft free of burrs, apply the mounting force on the correct ring and verify alignment between housings. Proper lubrication and correct internal clearance extend service life.

Regarding equivalents, inch bearings are identified by their nominal size and nomenclatures do not always match between manufacturers. The same size may appear with different letters or suffixes depending on the brand. Therefore, if you are going to replace a bearing, do not rely only on the code: compare the main dimensions and the type of protection. If in doubt, send us a photo or the code engraved on the bearing and we will verify it.
