Description

A SKF lock washer from the W series sits between the bearing lock nut and the bearing, holding the nut at the position you set. Two tabs do the work: the inner one locates in the shaft groove, the outer one folds over a nut face. Assemblies on shafts where a nut working loose would be a problem are where these washers belong.
Reading the code is simple once you know the pattern. The letter W comes first, then a two-digit number: W 00, W 02, W 03 and so on. That number is a size code, not a diameter, and each one pairs a particular inner diameter with a particular thickness for use with a given nut thread. Two washers with close numbers are not necessarily close in size, so the dimension table decides. Send us the part number and we match it exactly.
You will find these washers in food processing, cement and mining plants, and in maintenance shops that service rotating equipment. Gearboxes, pumps, fans and conveyors are typical locations, since bearings there run under load and vibration. Machine tools and continuous process lines use them as well.
Selection comes down to three things: shaft diameter, nut thread and the space available. The inner tab has to drop into the shaft groove and the outer tab has to reach a nut face. Thickness matters too, because the nut has to seat correctly on the washer. At mounting, check that the tab is intact and bend it firmly, without overworking the metal. Lubrication of the assembly also plays a part in how long it lasts.
Other manufacturers offer lock washers under similar designations, but that does not make them drop-in replacements. Inner diameter, outer diameter, thickness and tab position are what actually decide fit. When replacing one, compare against the original part or check with us. Give us the SKF part number, or the measurements, and we will point you to the right option.

Frequently asked questions
- What does the number in an SKF lock washer W 03 mean?
- It is a size code that ties an inner diameter to a thickness, not a diameter reading. Contact us for the exact measurements of W 03 and we will send the technical data.
- How is an SKF lock washer installed?
- Seat it in the shaft groove, thread the nut on, then bend an outer tab over one face of the nut so it cannot turn. Keep the tab undamaged and confirm the tightening afterward.
- Are lock washers from different brands interchangeable?
- Not always. Similar designations can still differ in diameter, thickness or tab position. Compare the measurements against the original part, or send us the part number.
