Product Overview: The KM 05 Lock Nut (M25x1.5)
The KM 05 is a precision-engineered metric Lock Nut, an essential component within our Bearing Accessories range. Specifically designed with an M25x1.5 thread, this lock nut is used to accurately locate and secure bearings and other mechanical components onto a 25mm shaft, preventing any axial movement during operation. It features four equally spaced slots around its circumference, allowing for easy and effective tightening or loosening using a standard hook or impact spanner.
For a secure and reliable installation, the KM 05 lock nut is designed to be used in conjunction with an MB 05 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 rotating loose under vibration or operational stress. This simple yet effective system is fundamental for the correct mounting of bearings on shafts and adapter sleeves.
Key Features of the KM 05 Lock Nut
- Precision Machined Thread: Features a standard M25x1.5 metric thread for a secure and accurate fit on the shaft.
- Four-Slot Design: Allows for easy tightening and adjustment with standard hook spanners, ensuring proper preload and security.
- Durable Steel Construction: Manufactured from high-quality steel to provide excellent strength and resistance to wear and deformation.
- System Compatibility: Engineered to work seamlessly with an MB 05 lock washer to create a reliable locking mechanism.
- Axial Securing: Effectively locks bearings and other components against a shaft shoulder, ensuring precise positioning.
- Reusable: Can be loosened and re-tightened multiple times without significant loss of performance, facilitating maintenance and adjustments.
Common Applications
- Bearing Mounting: Widely used to secure bearings onto adapter sleeves such as the H 205 or H 305.
- Industrial Gearboxes: Essential for locking gears, bearings, and other components onto transmission shafts.
- Electric Motors: Secures bearings on motor shafts to maintain rotor alignment and smooth operation.
- Pumps and Compressors: Used to fix impellers and bearings in place against dynamic forces.
- Conveyor Systems: Ensures that rollers and pulleys are securely fastened to their shafts.
- Agricultural and Construction Machinery: Provides a robust fastening solution for components in demanding and high-vibration environments.
Benefits of Using the KM 05 Lock Nut
- Enhanced Reliability: Prevents components from loosening due to vibration, thermal expansion, or rotational forces, increasing machine uptime.
- Precise Adjustment: Allows for accurate setting of bearing clearance or preload, which is critical for optimal performance and lifespan.
- Simplified Assembly: Offers a straightforward and effective method for mounting and dismounting bearings from a shaft.
- Cost-Effective Solution: Provides a reliable and inexpensive way to secure critical components, reducing the risk of costly failures.
- Increased Safety: A properly secured lock nut and washer combination prevents catastrophic failure caused by components moving out of position.
- Improved Component Life: By maintaining the correct position and preload, it reduces wear on bearings, shafts, and housings.
