TIMKEN lock washers

TIMKEN lock washers help preserve nut position in an arrangement designed for that locking system. They are retaining accessories rather than generic washers selected only by diameter. Their relationship with grooves, faces and nut must be checked together. This line differs from locknuts and from housing covers or locating rings, even when all appear in one bearing position's parts list.

MB, W and MBL spelling

MB0, W 07 and MBL24 illustrate three groups. MB and MBL connect directly to the number, while W 07 retains a space and initial zero. Do not remove L to match the MB series. W 07 records a 35 mm shaft attribute, which alone does not establish tab shape or compatible nut. Preserve the code and compare profile, thickness and locking details with documented parts.

The washer's relationship with the nut

In a sleeve or threaded-shaft arrangement, the washer sits beside the nut. Identify its connection to the shaft and the feature immobilizing the nut. Record orientation before removal and photograph associated grooves. A deformed washer can obscure original geometry; use a drawing or parts diagram rather than reconstructing the design from a bent tab alone.

Describing the locking profile

Give MR Accesorios Industriales the reference, quantity, nut code and shaft or sleeve details. Include both-face and installation photographs. Without markings, sketch bore, outside diameter, thickness and locking feature positions. State whether the nut is also required, keeping the two components under separate references rather than assuming an unspecified part is included.

Does a plain washer serve the same purpose?

Do not infer that; respect the specified locking system.

Is diameter sufficient for selection?

Profile and nut and shaft relationships also matter.

Should the nut code be retained?

Yes, it helps review the complete arrangement.
