Lock Nuts

If you need lock nuts, Simply Bearings stocks and supplies a comprehensive range of sizes to suit any budget, from the RU Budget range to our surprisingly affordable premium ranges supplied by our preferred manufacturer FAG and other high-quality suppliers such as SKF, NTN, Nachi, Timken and NSK.

Lock nuts - also known as locking nuts, shaft nuts or withdrawal nuts - have a wide range of applications. They are a simple and highly effective way of securing bearings on a shaft and are widely used in the engineering and automotive industries.

Lock washer lock nuts or locking nuts with ISO threads are used to securely locate bearings in the shaft and facilitate the mounting of taper bore bearings when used with an adaptor or withdrawal sleeve. They are efficient, secure and cost-effective, and they can be reused and removed.

Locking nuts with an integral locking device utilise a grub screw tightened against a pressure plate with a thread profile machined into it. When the screw is tightened, the threads cannot be damaged, and mounting and dismounting can be achieved with ease. No additional washers or nuts are required.

Our precision lock nuts with integral locking pins are ideal for a precision bearing installation where the ability to make minor radial alignment adjustments is required. This is achieved by accessing the locking pins, set at 120 degrees around the perimeter and diagonally to the ISO threads, which can be easily accessed via the chamfered front face.
