NSK locknuts provide axial retention within a bearing arrangement. They engage the shaft or sleeve thread specified by the design; they are neither bearings nor substitutes for a locking element. Unlike adapter or withdrawal sleeves, which form the mounting interface, the nut acts on its matching thread. Establishing which individual part needs replacement is the starting point for an accurate inquiry.

The catalog includes AN 02, AN 03 and ANL 24. Each designation has an initial letter group followed by a space and a number. AN and ANL are separate catalog groups, so retaining the L matters. The number identifies a reference within its group, but does not by itself document thread pitch, thread diameter or thickness. Keep zeros at the beginning and compare the nut geometry with the shaft or sleeve drawing before considering a replacement.
At a conveyor or fan bearing position, the nut may sit beside the inner ring and the parts locating it. Review the supporting shoulder, access for installation and the device preventing the adjusted nut from rotating. Different positions on one machine can use different arrangements. A nut appearing to screw on does not establish compatibility: its face contact and relationship with the locking device must also match the intended assembly.
For a quote from MR Accesorios Industriales, provide the readable code, quantity and associated bearing or sleeve reference. If markings are worn, include photographs of both faces and the thread, verified dimensions and a sketch of the location. State whether the request covers only the nut or additional accessories. Separate line items keep an individual component distinct from a complete assembly and allow missing information to be checked without inventing a reference.
Their similarity is insufficient; compare the thread and mounting geometry.
The reference identifies a nut; specify other components separately.
Add a side view and thread information to support identification.
