Product Overview: The KM 44 Metric Lock Nut
The KM 44 is a high-quality metric lock nut designed to securely position bearings and other mechanical components on a shaft. With a nominal thread diameter of 220 mm (M220x4 thread), this essential component is part of our extensive range of Bearing Accessories. Lock nuts are critical for preventing the loosening of bearings due to vibration or rotational forces, ensuring the reliability and longevity of machinery. The KM 44 features four slots on its outer circumference for tightening with a hook or impact spanner.
Typically used in conjunction with an MB 44 lock washer, the KM 44 provides a simple yet highly effective locking mechanism. It is commonly used to secure bearings with a 220mm bore, such as the 23244 Spherical Roller Bearing, onto an H 2344 adapter sleeve. As a leading supplier of industrial components, we ensure our Lock Nut collection meets precise industry standards for a dependable fit and lasting performance in demanding applications.
