Product Overview: The MB 21 Lock Washer
The MB 21 is a precision-engineered lock washer, an essential component in our Bearing Accessories collection. With an inner diameter of 105mm, an outer diameter of 138mm, and a thickness of 2mm, this washer is specifically designed to work in conjunction with KM 21 lock nuts. Its primary function is to secure bearings and other components onto a shaft, preventing the lock nut from loosening due to vibration or operational torque. This simple yet critical part ensures the reliability and safety of the entire bearing assembly.
As a key supplier of industrial mechanical parts, we provide high-quality MB 21 lock washers that meet stringent industry standards. The multiple external tabs on the washer are bent into the corresponding slots on the lock nut, creating a positive and secure mechanical lock.
