The NSK R series is a single-row deep groove ball bearing identified by an inch-based size code. It handles moderate radial and axial loads in both directions and runs at high speeds, which makes it suitable for compact assemblies, small appliances, power tools and light transmission drives. MR Industrial Accessories LLC supplies this series to customers throughout the United States and Latin America, and quotes by part number through WhatsApp or email.

Reading the code is straightforward: the R comes first, then a number that fixes the size inside the inch family. Codes written without a hyphen correspond to the basic sizes, while a hyphenated suffix points to a variant of bore or width within the same family. When you ask for a quote, copy the full code exactly as it appears on the drawing or on the bearing itself.

Typical applications include fans, small pumps, fractional-horsepower motors, sewing machines, laboratory instruments and door or shutter hardware. The series also shows up in spare parts for imported machinery that uses inch shafts, where matching the original size avoids machining or adapters. Because the section is reduced, it fits assemblies with limited radial space.

Selection depends on shaft and housing diameters, the load direction and magnitude, and the rotation speed. At mounting, verify alignment between shaft and support, keep blows away from the rings, and apply the mounting force to the ring that is being fitted. Lubrication and sealing choices follow the operating environment; where dust or moisture is present, it is worth reviewing variants with extra protection.

Interchange between brands relies on standardized boundary dimensions and the series code rather than on the trade name. If you have a bearing from another maker or an unidentified part, the main dimensions are usually enough to establish whether a replacement will fit. MR Industrial Accessories LLC supplies NSK and other brands, and can point you to the compatible option when one exists.

To move forward with a quote, send the R series code, the brand and, when possible, a photo of the part or the drawing through WhatsApp or email. Our team reviews the request and replies promptly, and can also suggest equivalents or help with the selection.
