The TIMKEN W series lock washer is a fastening component used to secure bearings and other machine elements. Its main function is to prevent rotation or axial displacement of lock nuts, ensuring that the assembly remains in its correct position during operation. It is a key part in assemblies where vibration or dynamic loads could loosen the fastening. MR Accesorios Industriales supplies this series as part of its line of power transmission components.
The designation of the W series is read with the letter W followed by a two-digit number indicating the size. For example, W 07, W 08, W 09, W 10, W 11, W 12, W 13 and W 19 correspond to different sizes. The number is not a diameter or a direct measurement, but a code that identifies the appropriate washer for each nut and bearing size. To select the correct one, it is essential to cross-reference this code with the bearing or nut you are going to secure.
These washers are used in a wide variety of industries in Argentina, such as metallurgy, food, cement and mining. They are common in equipment with spherical roller bearings, where secure fastening of the inner ring or the adjustment nut is required. They also appear in gearboxes, pumps, fans and conveyors. Their presence is critical in applications with high vibrations or loads that could loosen the assembly.
To choose the correct washer, take into account the size of the lock nut and the shaft diameter. The washer must fit into the grooves of the nut and the shaft to lock rotation. During mounting, make sure that the washer tab is fully inserted into the shaft groove and that one of the lugs aligns with a groove in the nut. It is advisable to replace the washer every time the nut is removed, since it can deform.
Regarding equivalences, lock washers are manufactured under standards that allow interchangeability between different brands. Although each manufacturer may have its own nomenclature, codes such as W 07 or W 08 usually correspond to standardized sizes. If you need to replace a washer from another brand, the safest approach is to compare the critical dimensions: inner diameter, thickness and tab location. MR Accesorios Industriales advises you to find the right equivalent.

Frequently Asked Questions
- How do I know which lock washer I need?
- You need to cross-reference the washer code with the bearing or lock nut. The number following the W indicates the size. If you send us the bearing part number, we will indicate the compatible washer.
- Are TIMKEN lock washers reusable?
- Reusing them is not recommended, since mounting and dismounting can deform them and reduce their effectiveness. Ideally, install a new one each time the assembly is serviced to ensure reliable fastening.
- Do they have equivalences with other brands?
- Yes, lock washers are usually interchangeable between brands if the dimensions and tab type match. If you provide us with the part number from another brand, we will help you find the TIMKEN equivalent or a compatible alternative.
