The SKF KM 17 locking nut is a critical accessory component designed for accurately securing bearings and other elements (such as pulleys or gears) onto a shaft. Manufactured to exacting standards, this metric locking nut features an M85x2 thread pitch and provides the necessary axial force to prevent unwanted loosening due to heavy industrial vibration, rotational stress, or shock loads. Its design is optimized for use in high-precision applications, ensuring that bearing clearance or preload adjustments remain precisely maintained throughout the operational life cycle. Made from high-quality carbon steel, the KM 17 guarantees exceptional durability and standardization, making it a reliable choice for maintenance and OEM projects requiring ISO standard compliance.
Selecting the KM 17 ensures operational reliability and simplifies maintenance procedures. This component is specifically designed to be used in conjunction with the standard MB 17 locking washer, where the tab of the washer fits securely into the keyway of the nut and the keyway of the shaft, providing a positive, fail-safe locking mechanism. Its robust construction supports increased uptime and reduces the risk of costly machinery failures associated with components coming loose. As part of the globally recognized SKF ecosystem, the KM 17 provides superior fit, finish, and performance compared to generic alternatives, safeguarding the longevity of your high-value rotating equipment.
