Product Overview: The KM 40 Lock Nut
The KM 40 is a high-quality, precision-engineered lock nut, essential for securely positioning bearings and other components on a shaft. Designed with a standard M200x3 thread, this component is a crucial part of our Bearing Accessories and Lock Nut range. Its primary function is to provide strong axial clamping force, preventing any unwanted movement of bearings mounted directly on a shaft or on adapter sleeves. The KM 40 is manufactured to strict industry standards to ensure a reliable and secure fit in various mechanical assemblies.
KM lock nuts are designed to be used in conjunction with a corresponding lock washer, such as the MB 40, which engages with a keyway on the shaft to prevent the nut from loosening due to vibration or operational torque. This simple yet effective locking mechanism is a staple in industrial machinery, ensuring long-term reliability and operational safety.
Key Features of the KM 40 Lock Nut
- Precision Threads: Features a metric M200x3 thread for accurate and secure engagement with the shaft.
- Four Locking Slots: Equipped with four equally spaced slots on its circumference for easy tightening and loosening using a hook or impact spanner.
- Durable Construction: Made from high-strength steel to withstand high axial loads and ensure long service life.
- Secure Locking System: Designed to work seamlessly with MB series lock washers to create a positive lock that resists loosening.
- Standardized Design: Manufactured according to international standards (e.g., DIN 981), ensuring interchangeability and consistent performance.
- Simple Installation: Allows for straightforward mounting and dismounting of bearings without the need for specialized equipment.
Common Applications
- Bearing Assemblies: Used to secure bearings with a tapered bore onto adapter sleeves (e.g., H 2340) or withdrawal sleeves.
- Industrial Gearboxes: Essential for locking gears and bearings in place on transmission shafts.
- Pumps and Compressors: Provides reliable axial location for rotating components in fluid and air handling equipment.
