Lock nuts

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

Product Description

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
