Product Overview: The MB 44 Lock Washer
The MB 44 is an essential fastening component from our range of Lock Washers, designed to secure corresponding KM 44 lock nuts on a shaft. With an inner diameter of 220 mm, an outer diameter of 280 mm, and a thickness of 3 mm, this washer provides a simple yet highly effective method for preventing bearing lock nuts from loosening due to vibration, rotation, or thermal expansion. It is a critical part of many bearing assemblies, ensuring that bearings, gears, and other components remain firmly in place.
The MB 44 lock washer features a single inner tab that engages with a keyway on the shaft, preventing the washer itself from rotating. Its circumference has multiple outer tabs, one of which is bent into a corresponding slot on the lock nut after tightening. This positive locking mechanism guarantees the nut's position, enhancing the overall safety and reliability of the machinery. As a key supplier of industrial Bearing Accessories, we provide high-quality components for robust and secure mechanical systems.
