Product Overview: The KM 11 Lock Nut
The KM 11 is a precision-engineered lock nut, also known as a shaft nut or bearing nut, designed to securely position bearings and other components onto a shaft or adapter sleeve. Featuring a standard metric thread of M55x2, this component is essential for preventing the axial loosening of bearings that can occur due to vibration or operational loads. It is a fundamental part of our Bearing Accessories collection, ensuring reliable and precise mounting in a wide range of mechanical assemblies.
The KM 11 lock nut is designed to be used in conjunction with an MB 11 lock washer. The nut features four equally spaced slots around its circumference, which allow a tang from the lock washer to be bent into one of the slots, effectively locking the nut in place and preventing it from rotating. This simple yet highly effective mechanism provides a secure and dependable mounting solution for bearings on shafts or sleeves like the H 211 and H 311.
Key Features of the KM 11 Lock Nut
- Precision Metric Thread: Manufactured with a standard M55x2 thread for compatibility with corresponding shafts and adapter sleeves.
- Secure Locking Mechanism: Features four circumferential slots designed for use with an MB 11 lock washer to prevent loosening.
- Durable Construction: Made from high-quality steel to withstand tightening forces and resist wear and tear in industrial environments.
- Easy Installation and Removal: Can be easily tightened or loosened using a standard hook or impact spanner, simplifying assembly and maintenance.
- Reusable Design: Can be reused multiple times provided the threads and locking surfaces are in good condition, offering a cost-effective solution.
- Accurate Bearing Positioning: Allows for precise adjustment of bearing clearance and secure axial location on the shaft.
Common Applications
- Industrial Gearboxes: Secures gear and bearing assemblies on input and output shafts.
- Electric Motors and Pumps: Used to mount bearings securely on motor shafts, ensuring rotor alignment and stability.
- Conveyor Systems: Locks bearings in place on conveyor rollers and drive shafts, crucial for continuous operation.
- Agricultural Machinery: Essential for securing bearings in equipment like combines, balers, and tillers that experience high vibration.
- Automotive Drivetrains: Used in transmission systems and wheel hub assemblies to lock bearings onto shafts.
- Machine Tools: Provides the precision axial location required for spindles and other rotating components in lathes and milling machines.
Benefits of Using the KM 11 Lock Nut
- Enhanced Operational Reliability: Prevents bearing slippage and axial movement on the shaft, reducing the risk of premature failure.
- Simplified Assembly Process: Provides a straightforward and effective method for securing bearings without complex procedures.
- Improved Machinery Lifespan: By maintaining correct bearing position and preload, it helps extend the service life of the entire rotating assembly.
- Cost-Effective Maintenance: A reliable and affordable component that reduces the need for frequent readjustments and costly repairs.
- Maintains Bearing Clearance: Allows for the precise setting of axial clearance or preload in bearing arrangements, optimizing performance.
- Resistant to Vibration: The combination of the lock nut and washer creates a system highly resistant to loosening from operational vibrations.
