Lock nuts are utilised to find bearings and other factors onto a shaft or adapter sleeve. They are also used for mounting bearings on tapered shaft seats and dismounting bearings from withdrawal sleeves.
Lock nuts have to be secured to avoid unintentional loosening. This is carried out, both by a locking system that engages a keyway in the shaft or essential slot in the adapter sleeve, or by a locking mechanism built-in in the nut.
