The SKF W series lock washer is a fastening component placed between the lock nut and the bearing to prevent the nut from loosening due to vibration. Its design with an inner and outer tab allows the nut to be locked in the desired position. It is used in bearing assemblies mounted on shafts, where secure adjustment is critical.

The W series designation is read as W followed by a two-digit number indicating the size. For example, W 00, W 02, W 03, etc. Each code corresponds to a specific combination of bore diameter and thickness, intended for nuts with different threads. The numeric suffix does not indicate the diameter directly; you must consult the dimension table for each case. At MR we provide the exact equivalent for the code you send us.

These washers are used in industries such as food, cement and mining, and in maintenance workshops for rotating equipment. They are common in gearboxes, pumps, fans and conveyors, where bearings operate under load and vibration. They are also found in machine tools and continuous process equipment. In Argentina, they are frequently requested for repairs of imported equipment that uses SKF bearings.

To select the correct washer, take into account the shaft diameter, the nut thread and the available space. The inner tab must fit into the shaft groove and the outer tab must be bent over one face of the nut. It is important that the washer has the right thickness so that the nut seats properly. During assembly, check that the tab is not damaged and that the bend is firm but not excessive. Lubrication of the assembly also affects service life.

As for equivalents, other brands make lock washers with similar designations, but they are not always interchangeable. The critical dimensions are the bore diameter, outer diameter and thickness, as well as the position of the tabs. If you need to replace a washer, the best option is to compare it with the original part or consult us. We do not invent codes: we ask for the SKF code or the dimensions to give you the correct option.

If you already have the code for your SKF lock washer, send it by WhatsApp to MR Accesorios Industriales and we will quote you. If you do not have it, send us the shaft and nut dimensions and we will help you identify it. We work with the SKF line and can advise you so that the assembly is secure.
