Product Overview: The MB 48 Lock Washer
The MB 48 is a precision-engineered lock washer, an essential component in our Bearing Accessories range. Specifically designed to be used with a KM 48 lock nut, this washer provides a simple yet highly effective method for securing bearings and other components onto a shaft. Measuring 240mm in bore diameter, 312mm in outer diameter, and 4.5mm in thickness, the MB 48 prevents the lock nut from loosening due to vibration or operational torque. Its design features an inner tab that locates in a shaft keyway and multiple outer tabs that can be bent into the corresponding slots on the lock nut, creating a secure mechanical lock. This ensures the entire bearing assembly remains tightly positioned, which is critical for the reliability and safety of rotating machinery.
Key Features of the MB 48 Lock Washer
- Positive Locking Mechanism: Prevents the corresponding KM lock nut from backing off or loosening under load and vibration.
- Simple and Reliable Design: Features an inner tab for shaft engagement and multiple outer tabs for locking into the nut.
- Durable Construction: Manufactured from high-quality spring steel for excellent strength and resilience.
- Precision Fit: Engineered to exact specifications for a secure fit with KM 48 lock nuts and associated shafts.
- Easy Installation: Can be installed and secured using basic hand tools, simplifying bearing mounting procedures.
- Reusable: In many cases, the washer can be carefully straightened and reused, offering a cost-effective solution.
