Family specifications and selection conditions
| Product description | KMTA precision lock nuts have a cylindrical outside surface and are intended for applications where high precision, simple assembly and reliable locking are required. The three equally-spaced locking pins enable these lock nuts to be accurately positioned at right angles to the shaft. However, they can also be adjusted to compensate for slight angular deviations of adjacent components. Maximum axial run-out between the locating face and thread (up to size 40): 0.005 mm. |
|---|---|
| Manufacturer features | No keyway required • Withstands high axial loads • Reliable, effective locking mechanism • Designed for frequent and simple installation and removal • Available for thread M 25x1.5 to M 200x3 (sizes 5 to 40) |
