Product Overview: The MB 28 Lock Washer
The MB 28 is a crucial component in our range of Bearing Accessories, designed to securely fasten KM 28 lock nuts onto shafts or adapter sleeves. With an inner diameter of 140 mm, an outer diameter of 180 mm, and a thickness of 2.5 mm, this Lock Washer provides a simple yet highly effective method for preventing the loosening of lock nuts caused by vibration, rotation, or thermal expansion. Its design features multiple tabs around the circumference; one internal tab locates in the shaft's keyway, while one of the outer tabs is bent into a corresponding slot on the lock nut to create a secure mechanical lock.
As a leading supplier of industrial components, we ensure our MB 28 lock washers are manufactured to precise industry standards using high-quality steel. This guarantees durability and reliable performance in demanding mechanical assemblies. This small but essential part plays a significant role in maintaining the integrity and safety of rotating machinery by ensuring bearings and other components remain fixed in their designated positions.
