The TIMKEN MB series lock washer is a locking component placed on the shaft to axially secure bearings and other machine elements. Its design with an inner and outer tab works together with a lock nut to prevent unwanted displacement. It is used in equipment where precision and mounting safety are critical, such as gearboxes, pumps and process machinery. MR Accesorios Industriales supplies it in Buenos Aires, Argentina.

The MB series designation is read as a sequential numeric code: MB0, MB1, MB2, MB3, MB4, MB5, MB6 and MB7. Each number indicates a different size within the family, and the washer is chosen according to the shaft diameter and the bearing to be secured. There are no additional suffixes in this series: the number alone defines the size. To select the correct one, the part number must be cross-referenced with the assembly dimensions.

These washers are used in industries such as food, petrochemical, steel and mining, where bearings work under loads and vibrations. They also appear in power transmission equipment, such as gearboxes and couplings, and in machine tools. In Argentina, they are commonly found in plant maintenance and in the repair of imported equipment requiring specific spare parts.

For correct mounting, check that the inner tab of the washer matches the shaft groove and that the outer tab is bent over one face of the lock nut. This ensures the mechanical lock. Lubrication of the assembly and cleanliness of the contact surfaces are key to avoiding premature wear. If the shaft has burrs or wear, it should be repaired before fitting the washer.

Lock washers are standardized components, so equivalents may exist between different brands. However, the critical dimensions — bore diameter, thickness and tab location — must match the original bearing and nut. When requesting a quote, provide the complete part number and, if possible, the shaft and bearing measurements. This way we can indicate the compatible alternative or manufacture it to measure if necessary.
