NSK angular contact bearings belong to arrangements where radial and axial loading are considered together. Contact orientation and the organization of supports matter during replacement. This page differs from the separate double row angular contact and thrust ball bearing lines, despite shared terminology. The reference and product record identify the construction used at the repaired position.

7003 A, 7203 B and QJ 206 are catalog references. The first two have numeric bases and separated letters; the third begins with QJ, a space and numbers. Record these groups without automatically assigning a contact angle or arrangement from abbreviated text. The QJ reference records a 30 mm bore, which does not describe the entire assembly. Preserve spacing and compare full markings with the machine drawing.
In a machine head or pump shaft support, the bearing can locate the shaft axially alongside other elements. During dismantling, record orientation, neighboring bearing, spacers and adjustment faces. A removed pair should not be treated as two unrelated parts without checking its intended arrangement. Machine assembly instructions take precedence over visual resemblance between series.
For MR Accesorios Industriales, provide complete code, quantity and whether the request concerns one position or several bearings together. Add both-face photographs, verified dimensions and assembly markings. Include prescribed adjustment and drawing orientation. Do not restore missing letters from memory or assume axial function is preserved by a matching bore. Separate measured facts from information still requiring confirmation.
Use the reference's documented record and specification.
Identify the original arrangement requirements first.
NSK has a separate line for those references.

The NSK A series angular contact ball bearing is a bearing designed to support radial and axial loads in one direction. Its design with offset raceways allows angular contact between balls and raceways, which gives it a higher axial load capacity than a deep groove ball bearing. It is used in applications where precision and rigidity must be combined, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we quote it on WhatsApp.
The QJ series angular contact ball bearing is a component designed to withstand combined radial and axial loads in a single direction. Its four-point contact design allows a single unit to replace combinations of bearings, simplifying assembly and reducing the space required. It is used in applications requiring high precision and rigidity, such as machine tool spindles, gearboxes and transmission equipment. MR Accesorios Industriales sells the NSK QJ series in Buenos Aires, Argentina, and advises you on selecting the correct part number for your application.
NSK B series angular contact ball bearings are components designed to support combined radial and axial loads in a single direction. Their design with offset raceways allows angular contact between the balls and the raceways, giving them a higher axial load capacity than a conventional deep groove ball bearing. They are used in applications where a shaft must be guided with precision and axial forces transmitted, such as pumps, compressors, spindles and gearboxes. MR Accesorios Industriales sells them in Buenos Aires, Argentina.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
