  • Lock nuts
    Lock nuts are used to locate bearing onto a shaft. Additionally, they can be used to mount bearing with a tapered bore onto tapered shaft seats and adapter sleeves, and to dismount bearing from withdrawal sleeves. Lock nuts are also frequently used to secure gears, belt pulleys and other machine components.

    Lock nuts have to be secured to prevent unintentional loosening by a locking device that engages a keyway in the shaft or key slot in the adapter sleeve, or a locking mechanism integrated in the nut.
    Lock nuts with integral locking reduce the cost of the shaft as no keyway is required. Installation is quicker and easier because no separate locking device is necessary. However, the loosening torque of these lock nuts requires more attention.

    Lock nuts with integral locking:
    * KMFE metric lock nuts with a locking screw
    * KMK metric lock nuts with an integral locking device
