Carbon Steel DIN981 Lock Nut with Surface Finishes Stainless Steel Locknut with Nylon Inserted

Product Description

 precision locknuts can guarantee the precise positioning of bearings and other mechanical parts in the axis. The nut has a simple structure, convenient usage, accurate positioning, high reliability, etc.  


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 keyway in the shaft or key slot in the adapter sleeve, or by a locking mechanism integrated in the nut.
