The SKF MB series lock washer is a fastening component used together with a slotted lock nut to secure bearings and other elements on threaded shafts. Its design with an inner tab and several outer tabs allows positive locking: one tab sits in the shaft groove and another is bent into a notch on the nut. This prevents the nut from loosening due to vibration or rotation. MR Accesorios Industriales carries this series as part of its line of bushings and adapter sleeves.

The MB series designation is read as MB followed by a number indicating the size. For example, MB 0, MB 1, MB 2, MB 3, MB 4, MB 5, MB 6 and MB 7 cover an increasing range of diameters. The number is not a direct measurement, but a code that corresponds to the lock nut of the same series. Each washer has an inner tab that fits into the shaft groove and several outer tabs that are bent over the notches on the nut. The numeric suffix lets you select the right washer according to the nut size.

SKF MB series lock washers are used in a wide variety of industrial applications in Argentina. They are found in gearboxes, pumps, fans, conveyors and process machinery, where they secure bearing lock nuts on shafts. They are also used in mining, cement, steel and food equipment. By securing the nut, they prevent loosening and maintain bearing preload, which extends the service life of the assembly. They are common in plant maintenance and equipment manufacturing.

To select the correct washer, take into account the size of the lock nut you are going to secure: the MB series corresponds to SKF KM nuts. Check that the inner tab fits into the shaft groove and that the outer tabs align with the notches on the nut. During assembly, bend one outer tab toward the nut with a suitable tool, without damaging the thread. It is important that the washer seats correctly and that the nut is in the desired position. Lubrication of the assembly and cleanliness of the threads also affect the result.

As for equivalents, SKF MB series lock washers are interchangeable with those from other brands that follow the same dimensional designation. However, not all brands use the same code; therefore it is advisable to verify the critical dimensions: inner diameter, outer diameter, thickness and number of tabs. If you need to replace a washer, send us the original part number and the shaft and nut measurements. At MR Accesorios Industriales we can guide you to find the equivalent part.
