Item details
The locknut is a component for axially fixing shaft-hub connections, for example a gear wheel on a shaft.
The locknuts have a comparatively large internal diameter and are screwed onto the shaft in order to exert axial pressure on the hub.
In most cases, however, this pressure is only used to hold the hub in place and not to create a frictional connection. One exception is the preload of roller bearings with shafts on bearings.
The locknut is normally used in combination with a lock washer in accordance with DIN 5406 to prevent unintentional loosening of the nut.
Locknuts are usually manufactured with a fine thread and require a corresponding hook wrench or locknut wrench for tightening and loosening.
