The SKF MBL lock washer works with a slotted lock nut to hold bearings and other components in place on threaded shafts. An inner tab engages the shaft groove, and one of several outer tabs is bent into a notch on the nut, keeping it from backing off under vibration. This series is part of the line of bearing accessories MR Industrial Accessories supplies to maintenance and purchasing teams across the United States and several Latin American countries.

The letters MBL identify SKF lock washers for metric shafts. The number that follows is the size code of the KML nut the washer pairs with, not the shaft diameter. MBL 24 matches KML 24, MBL 30 matches KML 30, and the pattern continues. That naming makes it straightforward to pick the washer once you know which lock nut goes on the shaft.

These washers show up in machine tools, transmission equipment, pumps, fans and conveyors, and in general bearing maintenance where a nut has to stay put on a shaft. They are common in manufacturing plants, metalworking shops and processing facilities.

Selection comes down to two things: the shaft diameter and the nut type. The inner tab has to sit in the shaft groove, and an outer tab is then bent over a notch in the nut to lock it. Use the correct size and the right tools so the washer is not deformed during mounting.

SKF MBL lock washers can be replaced by equivalents from other brands that follow the same dimensional standard. Check that the tab dimensions and the bore diameter match the original shaft and nut. If anything is unclear, send us the exact code and we will help you confirm the match.
