Lock Nuts
Secure Axial Load Retention and Vibration Resistance in Demanding Environments
General Information
We supply a comprehensive range of lock nuts, both original and compatible versions, designed for secure axial location of bearings and other components on shafts. Compatible with leading brands such as SKF, FAG, INA, NSK, and NTN, our lock nuts are manufactured to ensure precise fit and reliable performance in industrial environments.
These precision-engineered components are commonly used in conjunction with adapter sleeves, withdrawal sleeves, and other mounting systems for tapered bore bearings. Available in several locking methods—such as tab washers, locking clips, and integrated locking devices—our lock nuts help prevent shaft and bearing displacement, maintaining axial positioning under high vibration or load conditions.
Offered in various metric and inch thread sizes (including KM, KML, HM, HMZ, and hydraulic variants), our lock nuts meet or exceed DIN 981, ISO 2982-2, and other international standards. All models are available with worldwide shipping and technical advisory support.
