The FAG lock washer MB series is a locking component used to secure bearings and other elements on shafts, preventing them from loosening or shifting axially. It is combined with lock nuts to lock the assembly in the correct position. MR Accesorios Industriales carries this line as part of its range of bushings and sleeves, with more than 80 years of experience in the Argentine industrial market.
The designation of the MB series is read as an alphanumeric code where the letters identify the family and the number the size variant. For example, MB0, MB1, MB2 and MB3 correspond to different standard sizes. Each numeric suffix indicates a specific diameter and thickness, so it is essential to verify the exact part number before requesting a quote. If you need help interpreting the designation, you can consult us via WhatsApp.
These lock washers are used in a wide variety of industrial applications in Argentina, such as power transmission, pumping equipment, fans, conveyor belts and agricultural machinery. Their main function is to keep the lock nut in place, preventing vibrations or axial loads from loosening the bearing. They are common in factory plant maintenance, repair shops and new equipment assembly.
To select the correct washer, take into account the shaft diameter, the type of lock nut and the available space. Mounting requires the washer tab to fit into the shaft groove and one of its lugs to be bent over the nut to immobilize it. It is important to verify alignment and correct seating to ensure effective retention. Lubrication of the assembly also influences long-term performance.
Regarding equivalents and interchangeability, MB series lock washers are usually compatible between different manufacturers that follow similar dimensional standards. However, we always recommend confirming the exact dimensions and the type of mounting before replacing a part. MR Accesorios Industriales carries the FAG brand as part of its product line, and we can advise you on the most suitable option for your application.
If you already have the part number of the washer you need, write to us via WhatsApp and we will quote you shortly. We can also help you identify the correct part if you tell us the shaft dimensions and the type of nut.
