Precision Locknut MSR/MSA - SPIETH-MASCHINENELEMENTE GmbH & Co KG - #2

SPIETH locknuts offer a range of special system and production related technical benefits.

Under high 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 nut used for mounting roller bearings plays an important part in determining the quality of the enti­re bearing.

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.

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.
