The NSK R 2A is a single-row deep groove ball bearing with inch dimensions, built to handle moderate radial and axial loads in general-purpose machinery. It comes in various seal types and internal clearances, and is found in both industrial equipment and maintenance tools. MR Industrial Accessories supplies this NSK series and assists you in choosing the correct version for your application.

In the R series, the 'R' stands for an inch-based bearing, and the following number—like '2A' in R 2A—specifies the size within that series. Suffixes added after the number denote design details such as sealing method, internal clearance, or special execution. For this reason, always order using the full code as shown on the equipment or drawing, since each suffix alters the bearing's configuration.

Bearings in this series suit equipment with inch-dimensioned shafts, often seen in imported pumps, fans, conveyors, and process machinery. They are also common in low to medium speed applications, with grease or oil lubrication chosen according to the operating environment. Their design allows for straightforward mounting and reliable rotation.

When selecting a bearing, consider the sealing type: open versions permit relubrication and better heat dissipation, while sealed or shielded types offer protection against dust and moisture. Internal clearance should match mounting and temperature conditions. During installation, verify shaft and housing alignment, use appropriate tools, and avoid direct impacts on the raceways. Lubrication must be suitable for the speed and temperature.

Inch-series deep groove ball bearings are made by several manufacturers, each with its own part numbering. If your equipment has a code from another brand, an equivalent can be identified by dimensions and features, but it is wise to confirm interchangeability with a specialist. MR Industrial Accessories supplies the NSK line and can guide you to the correct replacement without guesswork.
