Product Overview: The KM 19 Bearing Lock Nut
The KM 19 is a high-precision metric lock nut, an essential component in our extensive range of Bearing Accessories. Specifically designed with a standard M95x2 thread, this Lock Nut is engineered to securely position bearings and other mechanical components on a shaft. It is most commonly used in conjunction with an MB 19 lock washer and an adapter sleeve, such as the H 219, to lock a bearing with a tapered bore onto a cylindrical shaft seat. This simple yet critical part prevents axial movement and loosening caused by vibration, ensuring the reliability and longevity of the entire bearing assembly.
Manufactured from high-quality steel, the KM 19 provides a durable and reusable fastening solution for a wide variety of industrial applications. Its precision-cut threads and multiple locking slots allow for straightforward installation and secure tightening, making it a trusted choice for maintenance professionals and engineers.
Key Features of the KM 19 Lock Nut
- Precision Threading: Features a standard metric M95x2 thread for a secure and accurate fit.
- Multiple Locking Slots: Equipped with several slots around its circumference to engage with the inner tab of a corresponding lock washer, ensuring a positive lock.
- Durable Steel Construction: Made from high-strength steel to withstand tightening forces and resist wear and corrosion.
- Simple Installation: Designed for easy tightening and loosening using a standard spanner or hook wrench.
- Effective Locking Mechanism: Prevents the nut from backing off due to vibration or operational loads, securing the bearing's axial position.
- Reusable Design: Can be used multiple times in various applications without compromising its locking effectiveness under normal conditions.
Common Applications of KM 19 Lock Nuts
- Bearing Assemblies: Used to secure bearings onto adapter sleeves or directly onto stepped shafts.
