Product Overview: The MB 11 Lock Washer
The MB 11 is a precision-engineered lock washer, an essential component within our Bearing Accessories collection. Specifically designed for use with KM 11 lock nuts, this washer provides a simple and reliable method for securing bearings and other components onto a 55mm shaft. Its primary function is to prevent the lock nut from loosening under vibration, rotation, or operational stress, ensuring the entire bearing assembly remains securely in place.
As a key part of any robust mounting system, the MB 11 features an inner tab that locates in a shaft's keyway and multiple outer tabs. Once the corresponding lock nut is tightened, one of the outer tabs is bent into a matching slot on the nut's circumference, creating a positive mechanical lock. This makes it an indispensable part for applications involving Adapter Sleeves and withdrawal sleeves. Trust our high-quality Lock Washers for superior performance and machine reliability.
