Product Overview: The KM 24 Lock Nut
The KM 24 is a precision-engineered metric lock nut, an essential component in our range of Bearing Accessories. Designed with a standard metric thread of M120x2, this Lock Nut is primarily used to securely locate bearings and other components onto a shaft, preventing any axial movement during operation. Its robust construction ensures a tight and reliable fit, making it indispensable for mounting bearings on adapter sleeves or directly onto stepped shafts.
The KM 24 features four equally spaced slots around its circumference, allowing for easy tightening and loosening using a standard hook or impact spanner. For maximum security, it is designed to be used in conjunction with a corresponding MB 24 lock washer. The washer's inner tab fits into a keyway on the shaft, and one of its outer tabs is bent into a slot on the nut to prevent it from loosening due to vibration or rotational forces. This simple yet effective mechanism provides a secure and reusable locking solution for countless industrial applications.
Key Features of the KM 24 Lock Nut
- Precision Metric Thread: Features a standard M120x2 thread for compatibility with corresponding shafts and sleeves.
- Four Locking Slots: Designed with four slots on its outer diameter for engagement with a hook spanner, facilitating proper tightening.
- Secure Axial Fastening: Effectively secures bearings and other components against a shaft shoulder, preventing axial displacement.
- Durable Steel Construction: Manufactured from high-quality steel to withstand high tightening forces and resist operational stresses.
- Reusable Design: Can be easily dismounted and reused without compromising its locking effectiveness.
- Paired Locking System: Intended for use with an MB 24 lock washer to create a dependable locking device that resists loosening.
Common Applications
- Adapter Sleeve Assemblies: Commonly used to press an adapter sleeve into the bore of a bearing and secure the entire assembly on a plain shaft.
- Industrial Gearboxes: Ensures that gears and bearings remain fixed in their designated positions on the shaft.
- Pumps and Compressors: Secures rotating components, contributing to the reliability and longevity of the equipment.
- Conveyor Belt Pulleys: Used to lock bearings in place on the shafts of conveyor rollers and pulleys.
- Agricultural Machinery: Provides a robust fastening solution for components in demanding environments like tractors and harvesters.
- Electric Motors and Fans: Secures bearings on motor shafts, ensuring smooth and stable rotation.
Benefits of Using the KM 24 Lock Nut
