Product Overview: The KM 25 Bearing Lock Nut
The KM 25 is a high-quality metric lock nut, an essential component within our range of Bearing Accessories. Specifically designed with an M125x2 thread, this lock nut is engineered to securely position bearings and other mechanical components onto a shaft or adapter sleeve. It features four equally spaced slots on its outer circumference, allowing for easy and precise tightening or loosening using a hook or impact spanner. For a complete and secure assembly, it is designed to be used in conjunction with a corresponding MB 25 lock washer, which prevents the nut from loosening under vibration or operational stress.
As a crucial part of our Lock Nut collection, the KM 25 provides a simple, reliable, and reusable solution for mounting bearings. Its robust construction ensures long-term performance in demanding industrial environments, making it a preferred choice for maintenance professionals and engineers. Trust our components for precise and secure bearing arrangements in your machinery.
Key Features of the KM 25 Lock Nut

- Four Spanner Slots: Designed with four equally spaced slots for balanced engagement with hook or impact spanners, facilitating proper installation and removal.
- Durable Steel Construction: Manufactured from high-strength steel to withstand high axial loads and resist deformation.
- Reusable Design: Can be mounted, dismounted, and reused multiple times without compromising its locking effectiveness, making it a cost-effective solution.
- Secure Locking System: When paired with an MB 25 lock washer, it creates a positive locking mechanism that prevents unintended loosening.
- Standardized Dimensions: Produced to industry-standard specifications, ensuring interchangeability and compatibility with other standard components.
Common Applications
- Bearing Mounting on Adapter Sleeves: Widely used to press a tapered bore bearing onto an adapter sleeve and secure the entire assembly to a cylindrical shaft.
- Bearing Positioning on Shafts: Used to accurately locate bearings and other components axially on a threaded shaft.
- Gear and Pulley Assemblies: Secures gears, pulleys, and sprockets, preventing them from moving along the shaft during operation.
- Heavy Industrial Machinery: Essential in equipment such as rolling mills, paper machines, and large fans where reliable component fixing is critical.
- Pump and Gearbox Systems: Ensures that bearings within pumps and gearboxes are held firmly in place, maintaining alignment and performance.
- Conveyor Systems: Used to lock bearings in conveyor rollers and drive pulleys, ensuring smooth and reliable material handling.
Benefits of Using the KM 25 Lock Nut
- Prevents Axial Movement: Reliably secures bearings against a shaft shoulder, eliminating unwanted axial play and ensuring stable operation.
- Simplified Installation and Removal: The design allows for straightforward tightening and loosening, reducing maintenance time and effort.
- Enhanced Operational Safety: Prevents components from coming loose due to vibration or shock loads, improving the overall safety of the machinery.
- Maintains Bearing Preload: Allows for the precise adjustment of bearing clearance or preload, which is crucial for optimal performance and service life.
- Cost-Effective Solution: Offers a reliable and reusable method for securing components, reducing the need for more complex or expensive alternatives.
- Increased Machine Reliability: By ensuring components remain securely in place, it contributes to longer service intervals and reduced machinery downtime.
