Locknuts and lock washers are used for the axial fixation of bearings on threaded shafts. They ensure a play free fit, prevent the bearing from loosening and allow precise adjustment of bearing clearance or preload.
Locknuts are made from high grade steel and are secured against rotation with a matching lock washer. The washer engages positively in the groove of the nut and is fixed to the shaft, creating a durable and vibration resistant connection.
