Product Overview: The KM 20 Lock Nut
The KM 20 is a high-precision industrial lock nut, an essential component within our range of Bearing Accessories. Specifically designed with an M100x2 thread, it is engineered to securely locate bearings and other components onto a 100mm diameter shaft. This lock nut works in tandem with an MB 20 lock washer to prevent loosening caused by vibration or operational torque. Its primary function is to provide a reliable and simple method for axial locking, ensuring the stability and longevity of rotating machinery.
Manufactured to internationally recognized standards, the KM 20 features four equally spaced slots around its circumference. These slots allow for easy and precise tightening using a standard hook or impact spanner. As a key part of our Lock Nut collection, it is indispensable for mounting bearings on adapter sleeves or directly onto stepped shafts in a wide variety of industrial applications.
