Product Overview: The KM 48 Lock Nut
The KM 48 is a high-precision mechanical fastening component, commonly known as a Lock Nut or shaft nut. Engineered with an M240x4 thread, this robust accessory is essential for securely locating bearings and other components onto a shaft. It is designed to be used in conjunction with an MB 48 lock washer to prevent loosening caused by vibration or operational stresses. As a critical part of our Bearing Accessories range, the KM 48 ensures that bearings are mounted correctly, maintaining the required preload and clearance for optimal performance and longevity.
Manufactured from high-strength steel, the KM 48 lock nut provides a simple yet highly effective method for axial locking. Its four equally spaced slots on the outer circumference allow for easy tightening and loosening using a standard hook or impact spanner, making installation and maintenance straightforward. This component is indispensable in heavy-duty industrial applications where reliability and safety are paramount.
Key Features of the KM 48 Lock Nut
- Precision Threading: Features a standard M240x4 metric thread for a secure and accurate fit on the shaft.
- Positive Locking Mechanism: When used with an MB 48 lock washer, it provides a reliable locking system that prevents the nut from backing off.
- Durable Construction: Made from high-quality steel to withstand high axial loads and ensure long-term durability.
- Simplified Installation: The peripheral slots are designed for use with hook spanners, allowing for simple and damage-free tightening.
- Reusability: The nut is designed to be reused multiple times without compromising its locking effectiveness, provided it is not damaged.
- Standardized Design: Manufactured to industry standards, ensuring interchangeability and compatibility with corresponding components.
Common Applications
- Adapter Sleeve Assemblies: Used to press a bearing with a tapered bore onto an adapter sleeve like the H 2352, securing the entire assembly to the shaft.
- Withdrawal Sleeve Mounts: Facilitates the securing of bearings on withdrawal sleeves.
- Stepped Shafts: Provides a firm abutment for positioning bearings accurately against a shaft shoulder.
- Heavy Industrial Machinery: Essential in equipment such as rolling mills, large fans, and industrial gearboxes where components are subject to significant forces.
- Mining and Construction Equipment: Ensures the stability of rotating parts in crushers, conveyors, and excavators.
- Pulp and Paper Machines: Secures large rollers and shafts, maintaining alignment and preventing axial drift.
- Power Generation: Used in turbines and large electric motors to lock bearings in place securely.
Benefits of Using the KM 48 Lock Nut
- Enhanced Operational Safety: Prevents components from coming loose during operation, reducing the risk of catastrophic machinery failure.
- Improved Bearing Performance: Ensures correct axial positioning and preload, which is critical for extending the service life of bearings.
- Reduced Maintenance Time: The straightforward design allows for quick and easy installation, adjustment, and removal.
- Cost-Effective Solution: Offers a reliable and economical method for securing bearings compared to more complex locking systems.
- Prevents Shaft Damage: Secures components without damaging the shaft threads, preserving the integrity of expensive parts.
- Increased Machine Reliability: By maintaining the integrity of the bearing assembly, it contributes to the overall reliability and uptime of the machinery.
