The TIMKEN W series lock washer is a fastening component that keeps lock nuts from rotating or shifting axially. By locking the nut in place, it helps maintain the correct position of bearings and other machine elements during operation. This is especially important where vibration or dynamic loads could otherwise loosen the assembly. MR Industrial Accessories includes this series in its line of power transmission components.

The W series code consists of the letter W followed by a two-digit number that indicates size. Examples include W 07, W 08, W 09, W 10, W 11, W 12, W 13 and W 19. That number is not a diameter or a direct measurement; it is a reference that identifies the washer matching a particular nut and bearing size. To select the correct washer, always cross-reference the code with the bearing or nut you intend to secure.

These washers are found in many industries, including metallurgy, food processing, cement and mining. They are common in equipment with spherical roller bearings, where the inner ring or adjustment nut must be held securely. Gearboxes, pumps, fans and conveyors also use them. In applications with high vibration or loads that could loosen the assembly, their role is critical.

When choosing a washer, consider the lock nut size and the shaft diameter. The washer must engage the grooves of both the nut and the shaft to prevent rotation. During installation, ensure the washer tab is fully seated in the shaft groove and that one of the lugs aligns with a groove in the nut. Replacing the washer each time the nut is removed is advisable, as it can deform.

Lock washers are made to standards that allow interchangeability between brands. Manufacturers may use their own nomenclature, but codes such as W 07 or W 08 typically correspond to standardized sizes. If you are replacing a washer from another brand, compare the critical dimensions: inner diameter, thickness and tab location. MR Industrial Accessories can help you find the right equivalent.
