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.
KM Locking Nuts (AN Locking Nuts) are often referred to as Bearing Nuts or Shaft Nuts. They are commonly used in conjunction with suitable tab washers to securely locate bearings and other components onto a shaft. They can also be utilized when mounting taper bore bearings onto shafts.
KM Lock Nuts have four-equally-spaced slots machined into the outer diameter of the nut, enabling the nut to be secured into position using the approproate tab washer by bending the tab into the slots.
