Lock Nuts

Lock nuts are used to locate bearings and other components 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 prevent unintentional loosening. This is done, either by a locking device that engages a key way in the shaft or key slot in the adapter sleeve, or by a locking mechanism integrated in the nut.

Lock nuts with an integrated locking mechanism reduce the cost of the shaft as no key way is required. Installation is also quicker and easier because no separate locking device is necessary. However, the loosening torque of these lock nuts requires more attention. For information on loosening torque, refer to the product data sections for the various lock nut series.
The lock nuts listed here constitute the basic assortment. Lock nuts with other locking methods can be supplied on request. For additional information, contact the application engineering service.
