Product Overview: The KM 33 Lock Nut
The KM 33 is a precision-engineered metric Lock Nut, designed to securely locate bearings and other components onto a shaft. With a standard M165x3 thread, this lock nut is an essential part of our Bearing Accessories range. It works in conjunction with a corresponding MB 33 lock washer to provide a reliable and simple method for axial fastening. The KM 33 features four equally spaced slots on its outside diameter, allowing for precise tightening and locking into place with one of the lock washer's tabs.
Manufactured from high-strength steel, the KM 33 ensures a secure fit, preventing axial movement and maintaining the correct bearing clearance and position during operation. It is commonly used for mounting bearings on adapter sleeves, such as the H 2334, or directly onto stepped shafts in a wide variety of industrial applications.
