Product Overview: The MB 33 Lock Washer
The MB 33 is a high-quality lock washer, an essential component in our extensive range of Bearing Accessories. Designed with precision, this washer has a bore diameter of 165mm and is specifically engineered to work in conjunction with a KM 33 lock nut. Its primary function is to securely lock a bearing onto a shaft, preventing the lock nut from loosening due to vibration or operational torque. The MB 33 features an inner tab that locates in the keyway of the shaft or adapter sleeve, and multiple outer tabs that can be bent into the corresponding slots on the lock nut to create a positive mechanical lock.
As a leading supplier of industrial parts, we provide reliable and standardized components like the MB 33 to ensure the safety and longevity of your machinery. This simple yet critical part is fundamental for mounting bearings with adapter or withdrawal sleeves.
