Look Nuts KMT, KMTA & KMK
Adjustable to minimise runout
Both KMT and KMTA lock nuts have the same unique design using three equally spaced locking pins aligned at the same angle to the shaft axis as the thread flanks (see diag.). This design makes it very easy to align the lock nut at right angles to the shaft axis. The locking pins can be individually adjusted to minimise radial and axial runouts.

Loosening Torque
The above graph illustrates the locking capability of the nuts described in this brochure. The lock nuts were tested on a threaded shaft and screwed tightly against a shoulder. No axial load was applied.
Permissible Axial Load
KMT and KMTA lock nuts withstand higher axial loads than most other lock nuts because the entire threaded length of the nut can absorb the load (see graph 2).
Keeping a firm grip on trouble-free operation
Trouble-free operation of bearings and other components depends not only on the components in question but also on the adjacent parts. Correct mounting and regular maintenance are no less important in order to prevent unplanned machine downtime. Many operators know this correlation and take the appropriate care. Therefore, these lock nuts are used in many different production areas. They contribute to high quality, high reliability and the high precision of the final product.
