KM (AN) Series Lock Nuts

Lock Nuts (Locking Nuts) are sleeve accessories. They are used to locate bearings onto a shaft. Additionally, lock nuts 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 many other machine components.
