Product Overview: The MB 38 Lock Washer
The MB 38 is a high-quality lock washer, an essential component in our extensive range of Bearing Accessories. With an inner diameter of 190 mm, an outer diameter of 245 mm, and a thickness of 2.5 mm, this washer is specifically designed to secure the corresponding KM 38 lock nut. Its primary function is to prevent the nut from loosening due to vibration or operational torque, ensuring that bearings remain firmly positioned on a shaft or adapter sleeve.
As a key part of the Lock Washer series, the MB 38 utilizes a simple yet highly effective tab-locking mechanism. One of its inner tabs is bent into a keyway on the shaft, while one of the outer tabs is bent into a corresponding slot on the lock nut, creating a secure mechanical lock. This reliable locking method is crucial for the longevity and safety of rotating machinery. Explore our full range of locking components to ensure your assemblies are secure and dependable.
