Description: Lock nuts are a bearing accessory used to locate bearings or other accessories onto a shaft, and facilitate mounting and dismounting from shafts or sleeves. They must be secured to prevent unwanted loosening, which is done by either a separate locking device that engages a key slot in the sleeve or a keyway in the shaft, or a locking mechanism integrated in the nut itself. A multitude of factors should be considered when choosing or replacing a lock nut, such as axial and radial space, load capacity, dynamic behavior, precision, frequency of assembly, shaft rotation, and more. The type of lock nut desired will depend on the application of the bearing and cost limitations. MRO Supply carries a variety of locking types, materials, and designs for lock nuts of different applications, such as industrial or precision. Ask our experts about which type of lock nut is best for certain bearings, and for information on proper fitting and assembly.
