| | | SPIETH Locknuts Series MSR-MSA | | |
| | | |
| | | SPIETH locknuts offer a range of special system and production related technical benefits. Under high professional levels of dynamic stress, the good axial rigidity, high axial load capacity and the outstanding locking properties offered by this locknut series are of decisive importance. Simple connecting elements, no grooves, locking plates etc. | | |
| | | The locknut contact surface can be adjusted simply and precisely at any axial position. The produced high standard of run-out accuracy is retained when mounted and can be improved - if necessary - by setting individual adjustment. | | |

| | | Functional principle: | | |
| | | |
| | | Screwing on the locknut, the existence of thread flank play allows the nut to tilt. The contact surface of the nut can come to rest positioned at an incline. | | |
| | | |
| | | Thread flank play eliminated, the locknut is centred and can no longer tilt. The nut's contact surface has aligned at right-angles to the spindle axis. | | |
| | | The principle is shown in a simplified diagram with enlarged thread flank play. | | |
