Product Overview: The KM 38 Lock Nut
The KM 38 Lock Nut is a precision-engineered mechanical component designed for securing bearings and other machine parts onto a shaft. With a standard metric thread of M190x4, an outer diameter of 240mm, and a thickness of 22mm, this lock nut provides a reliable and straightforward method for axial location. As a crucial part of our Lock Nut collection, the KM 38 is manufactured from high-quality steel to ensure durability and consistent performance in demanding industrial environments. It is designed to be used in conjunction with an MB 38 lock washer, which prevents the nut from loosening due to vibration or operational torque.
These nuts are essential Bearing Accessories used for mounting bearings with a tapered bore onto an adapter sleeve, such as the H 2338, or directly onto a threaded shaft. The four equally spaced slots on its outer circumference allow for easy tightening and loosening using a hook or impact spanner, simplifying both installation and maintenance procedures.
Key Features of the KM 38 Lock Nut
- Precision Threads: Features a standard M190x4 metric thread for a secure and accurate fit.
- High-Strength Steel Construction: Manufactured from durable steel to withstand high axial loads and resist wear.
- Secure Locking Mechanism: Works with an MB 38 lock washer to effectively prevent loosening under operational stress and vibration.
