Product Overview: The KM 07 Lock Nut
The KM 07 Lock Nut is a crucial component in our Bearing Accessories collection, designed to securely locate bearings and other components onto a shaft. Featuring a standard M35x1.5 thread, this lock nut, often referred to as a shaft nut or bearing nut, is essential for preventing the axial movement of bearings, particularly when mounted on an adapter sleeve like the H 207. Its primary function is to press the tapered bore of a bearing up the sleeve's taper, achieving a secure fit and maintaining the correct operational clearance.
Used in conjunction with a corresponding MB 07 Lock Washer, the KM 07 provides a simple yet highly effective locking mechanism. The washer's inner tab fits into a keyway on the shaft or sleeve, and one of its outer tabs is bent into one of the slots on the lock nut's circumference, preventing it from loosening due to vibration or operational stresses. This ensures long-term reliability for the entire bearing assembly.
Key Features of the KM 07 Lock Nut
- Precision Threading: Manufactured with a standard M35x1.5 thread for a secure and accurate fit.
- Four Locking Slots: Features four equally spaced slots on its outer circumference to engage with a lock washer tab.
- Durable Construction: Made from high-quality steel to withstand tightening forces and resist wear.
- Secure Locking System: Works with an MB 07 lock washer to provide a reliable locking device against loosening.
- Simplified Mounting: Allows for easy and precise adjustment of bearing clearance and preload during installation.
- Reusable Design: Can be dismounted and reused multiple times without significant loss of performance, provided it is not damaged.
Common Applications
- Bearing Mounting: Widely used for securing bearings with a tapered bore onto adapter sleeves or withdrawal sleeves.
- Industrial Gearboxes: Essential for locking gears and bearings in place on transmission shafts.
- Pumps and Compressors: Secures rotating components to ensure stable and efficient operation.
- Conveyor Systems: Used to fix bearings in conveyor rollers and drive pulleys, preventing axial displacement.
- Agricultural Machinery: Applied in equipment like harvesters and tractors to secure wheel hub bearings and other critical parts.
- Electric Motors: Helps to locate and secure bearings on motor shafts, reducing vibration and noise.
- Plummer Block Housings: An integral part of mounting self-aligning bearings in various bearing housing units.
Benefits of Using the KM 07 Lock Nut
- Enhanced Reliability: Prevents bearing loosening, which can lead to catastrophic failure and machine downtime.
- Precise Axial Location: Ensures bearings and other components are accurately and firmly positioned on the shaft.
- Easy Installation & Removal: Can be tightened or loosened using a standard hook or impact spanner, simplifying maintenance.
- Cost-Effective Solution: Provides a reliable and inexpensive method for securing components compared to more complex alternatives.
- Improved Safety: A properly secured bearing assembly enhances the overall operational safety of machinery.
- Vibration Resistance: The lock nut and washer combination effectively counteracts the effects of vibration and rotational forces.
