The SKF WF series lock washer keeps bearings and other shaft-mounted components from working loose under vibration or axial load. It works together with a lock nut: once the nut is tightened, the washer tab is folded into a groove on the shaft, locking the assembly. This makes it a common choice in drives and machinery where reliable fastening matters. MR supplies this series.
Reading the WF code is straightforward. The letters WF indicate the washer type, and the number that follows is a size code, not the shaft diameter itself. Models such as WF-90, WF-140 and WF-160 are simply successive sizes in the series. That numbering lets you match a washer to a given shaft size and to the lock nut it will be used with.
These washers appear in many industrial settings: gearboxes, mills, conveyors, pumps and mining equipment, among others. Their job is to hold bearings firmly on the shaft while the machine runs, absorbing vibration and axial forces. Plants in food processing, cement, steel and oil depend on this kind of fastening to keep equipment running properly.
Selection comes down to two checks: the washer must suit the shaft diameter, and its tab must seat correctly in both the shaft groove and the nut. During installation, clean the mating surfaces, tighten the nut to the specified torque, then bend the tab into a groove. Because a tab that has been flexed too often can stop holding, it is worth inspecting the washer at service intervals.
In terms of interchangeability, WF series washers can be substituted with parts from other makers that share the same dimensional standard. Tolerances and material still need to be confirmed so the fit is correct. MR carries this series within its fastening range, and it is always a good idea to review the technical data before swapping in a washer from a different source.

Frequently asked questions
- How do I determine which WF lock washer I need?
- Start with your shaft diameter and the lock nut you plan to use. The number in the WF code is a size code, not the shaft diameter, so WF-140 does not mean a 140 mm shaft. If you are unsure, tell us your shaft size and we will help you select.
- Can WF washers be used with lock nuts from other manufacturers?
- They are made to work with lock nuts that follow the same dimensional standards. Before assembly, check that the tab fits the nut groove properly. Share the parts you are using and we can advise you.
- What material are SKF lock washers made from?
- They are typically carbon steel with a surface treatment for corrosion resistance. Stainless steel may be available for specific applications. Tell us about your operating environment and we will confirm the options.
