For equipment built around inch dimensions, the NSK Inch Series deep groove ball bearing provides a single-row solution that handles moderate radial and axial loads in both directions. It fits imported machinery and US-origin production lines where shaft and housing measurements follow inch standards. MR Industrial Accessories supplies this line and assists in matching the exact part number to your application.

The part number itself tells you a lot. The leading R signals the inch dimensional series; the following digits, as in R 2A ZZ, set the size within that series. Suffixes carry the configuration: ZZ means two sheet metal shields, a non-contacting closure that keeps lubricant in and dust out. Other suffixes may point to a steel cage, a specific internal clearance or a particular lubricant, depending on how the bearing will be used.

You will find these bearings in centrifugal pumps, industrial fans, conveyors, machine tools and process equipment across food, chemical and petrochemical plants. They are common where housings and shafts are measured in inches and where adapting to a metric bearing would mean modifying the housing. MR Industrial Accessories supplies them for replacement and maintenance programs.

Selection starts with the shaft and housing diameter in inches, then the load type and the operating environment. The ZZ shield works well where dust and moderate humidity are present; for water or fine particles, evaluate contacting seals instead. Also confirm shaft-to-housing alignment, internal clearance and proper lubrication. An incorrect fit during mounting will shorten service life.

Inch series deep groove ball bearings can be interchanged between brands when the main dimensions and seal type match. When sourcing a replacement, compare the complete part number, suffixes included, because small differences in internal clearance or lubricant affect performance. If you only have another brand's number, MR Industrial Accessories can identify the compatible equivalent. We can also help when the part has no visible identification.
