For smaller locknuts
Tab washers MB and MBL are simple, reliable elements for securing smaller locknuts (series KM and KML).
They have an inner tab and several outer tabs evenly spaced around the circumference. The inner tab grips in the slot on the adapter sleeve or shaft, one of the outer tabs is bent into a slot in the nut for location.
The washers are made from steel and the tensile strength of the material is at least 300 N/mm2.
For locknuts HM30 and HM31
Retaining brackets MS are used to secure locknuts HM30 and HM31.
The retaining brackets are fixed to the locknut using a hexagonal screw. They engage in a slot in the nut and in the adapter sleeve or shaft.
The fixing screws are secured with a retainer.
