The NSK Inch Series deep groove ball bearing is a single-row bearing with inch dimensions, designed to withstand moderate radial and axial loads in both directions. It is used in equipment where the housing and shaft follow inch measurements, such as imported machinery or production lines with components of US origin. MR Accesorios Industriales sells this line and helps you identify the exact part number for your equipment.

The Inch Series designation is made up of letters and numbers that indicate the bearing type and its variants. The initial letter R identifies the inch dimensional series. The number that follows, as in R 2A ZZ, indicates the size within that series. The suffixes ZZ correspond to two sheet metal shields, a non-contacting seal that retains lubrication and protects against dust and dirt. Other suffixes may indicate a steel cage, internal clearance or special lubricant, depending on the application.

These bearings are used in equipment with inch shafts and housings: centrifugal pumps, industrial fans, conveyors, machine tools and process equipment in food, chemical and petrochemical plants. In Argentina they are found in imported lines of US origin and in machines where the housing is not to be modified to adapt a metric bearing. MR Accesorios Industriales sells them for replacement and maintenance.

To select the correct bearing, take into account the shaft and housing diameter in inches, the type of load and the environmental conditions. The ZZ seal is suitable for environments with dust and moderate humidity; if there is water or fine particles, contacting seals should be evaluated. Check the alignment between shaft and housing, the internal clearance and proper lubrication. Mounting with incorrect fit shortens the bearing's service life.

Inch series deep groove ball bearings can be interchanged between brands if the main dimensions and the seal type match. When looking for a replacement, compare the full part number, including suffixes, because small differences in internal clearance or lubricant change performance. If you have the part number from another brand, MR Accesorios Industriales tells you the compatible equivalent. We can also help you if the part has no visible identification.
