Lock washers in the FAG MB series hold lock nuts in place on shafts, keeping bearings and related components from shifting axially. MR Industrial Accessories supplies this line as part of its range of bushings and sleeves. These washers work together with lock nuts to lock the assembly in position.
The MB code combines letters and numbers: the letters denote the family, while the number indicates the size variant. Standard sizes include MB0, MB1, MB2 and MB3, each with its own diameter and thickness. Because the numeric suffix defines those dimensions, confirm the exact part number before requesting a quote. If the designation is unclear, our team can help you interpret it via WhatsApp or email.
These lock washers appear in power transmission, pumping equipment, fans, conveyor belts and agricultural machinery. Their job is to keep the lock nut from backing off when vibration or axial loads are present, so the bearing stays put. Maintenance departments, repair shops and assembly operations all use them.
Selection depends on shaft diameter, the lock nut type and the space available. During mounting, the washer tab goes into the shaft groove, and one lug is bent over the nut to immobilize it. Check alignment and seating for effective retention. Lubrication of the assembly also affects long-term performance.
MB lock washers generally interchange between manufacturers that follow similar dimensional standards. Even so, confirm exact dimensions and mounting style before replacing a part. MR Industrial Accessories supplies the FAG brand within its product line and can advise on the most suitable option for your application.

- Lock washers that follow similar dimensional standards are often interchangeable between manufacturers. We recommend verifying exact dimensions and the mounting system before replacing a part. We can advise based on your application.
