Locknut

These nuts are used for the detection of location of bearings and other components onto a shaft or adapter sleeve. One of the other utility of these are escalating bearings on the tapered shaft seats and descending bearings from the withdrawal sleeves.

Unintentional loosening of these locknuts are prevented by securing these nuts. The nuts are thus fitted with a locking device that engage a keyway in the shaft or a key slot in the adapter sleeve, or by a unique mechanism integrated in the nut that locks the nut.

It is better used with an integrated locking system as it is cost effective, reducing the cost of the keyway in the shaft. This also facilitates quicker installation as no separate locking device is needed.
