Product Overview: The MB 15 Lock Washer
The MB 15 is a precision-engineered lock washer, designed as an essential component for securing bearings and other mechanical parts onto a shaft. Specifically, it works in conjunction with a KM 15 lock nut to prevent unintentional loosening caused by vibration or operational torque. Measuring 75mm in bore diameter, 102mm in outer diameter, and 1.5mm in thickness, this washer provides a reliable and straightforward mechanical locking mechanism for bearing assemblies.
As part of our comprehensive range of Bearing Accessories, the MB 15 is crucial for applications utilizing Adapter Sleeves or withdrawal sleeves. Its design features an inner tab that locates in the keyway of the sleeve or shaft, and multiple outer tabs that are bent into the corresponding slots on the lock nut, creating a secure and positive lock. This ensures the entire assembly remains tightly fixed, enhancing machine safety and performance.
Key Features of the MB 15 Lock Washer
- Secure Locking System: Provides a positive mechanical lock for KM 15 lock nuts, effectively preventing loosening.
- Precision Fit: Manufactured to strict tolerances to ensure a perfect fit with the corresponding nut and shaft.
- Durable Construction: Made from high-quality spring steel for excellent strength and resilience.
- Inner and Outer Tabs: Features a single inner tab to engage with a shaft keyway and multiple outer tabs for locking into the nut.
- Simple Installation: Easy to install and secure, requiring only basic tools to bend the tabs into place.
- Reusable Design: Can be carefully unbent and reused in some applications, offering good value.
Common Applications
- Bearing Mounting: Essential for securing bearings onto adapter sleeves (e.g., H 315) or directly onto stepped shafts.
- Industrial Gearboxes: Used to lock nuts that secure gears and bearings on transmission shafts.
- Electric Motors and Pumps: Ensures that rotating components remain securely in place during operation.
- Conveyor Systems: Secures bearings on conveyor rollers and drive shafts, resisting constant vibration.
- Agricultural Machinery: Widely used in equipment like harvesters and tractors where components are subject to high stress and vibration.
- Fans and Blowers: Prevents the loosening of fan hubs and bearing assemblies on motor shafts.
- Mining and Construction Equipment: Provides reliable fastening in heavy-duty machinery operating in harsh environments.
Benefits of Using the MB 15 Lock Washer
