Product Overview: The MB 13 Lock Washer
The MB 13 is a precision-engineered lock washer, an essential component in our range of Bearing Accessories. Designed specifically to work with the KM 13 lock nut, this washer provides a simple yet highly effective method for securing bearings onto a shaft or adapter sleeve. Featuring a 65mm bore diameter, the MB 13 is a critical part of a complete bearing assembly, preventing the lock nut from loosening due to vibration or operational stresses.
As a key supplier of industrial components, we ensure our Lock Washers are manufactured to strict industry standards. The MB 13 includes an inner tab that locates in the keyway of the shaft or adapter sleeve, and multiple outer tabs that can be bent into the corresponding slots on the lock nut, creating a secure mechanical lock. This prevents relative rotation between the nut and the shaft, ensuring the bearing maintains its correct position and preload.
Key Features of the MB 13 Lock Washer
- Positive Locking: Employs a tab-locking mechanism that physically prevents the lock nut from backing off.
- Simple Installation: Easy to install and secure by bending one of the outer tabs into a slot on the lock nut.
- Durable Material: Constructed from high-quality steel to withstand operational forces and ensure long-term reliability.
- Precision Fit: Manufactured to precise dimensions (65x85x1.5mm) for a perfect match with KM 13 lock nuts and corresponding shafts.
- Vibration Resistance: Effectively counteracts the loosening effects of vibration and dynamic loads in machinery.
- Reusable: Can often be reused if the tabs are carefully unbent, though replacement is recommended for critical applications.
Common Applications
- Industrial Gearboxes: Secures bearings on input and output shafts, maintaining gear alignment.
- Pumps and Compressors: Ensures that bearings within rotating assemblies remain firmly in place.
- Conveyor Systems: Used in roller assemblies to lock bearings onto shafts, preventing axial movement.
- Electric Motors: Secures bearings on motor shafts, contributing to smoother and more reliable operation.
- Agricultural Machinery: Provides a robust locking solution for equipment subject to high vibration and harsh conditions.
- Automotive Drivetrains: Applied in transmissions and axle assemblies to secure bearings and gears.
- Heavy Machinery: Essential for mounting large bearings in construction, mining, and manufacturing equipment.
Benefits of Using the MB 13 Lock Washer
- Enhanced Safety and Reliability: Prevents catastrophic failure that could result from a loosened bearing or nut.
- Increased Machine Uptime: Reduces the need for frequent re-tightening and maintenance, leading to less downtime.
- Cost-Effective Security: Offers an inexpensive and proven method for securing critical components.
- Maintains Bearing Preload: Ensures that the axial preload set during installation is maintained throughout operation.
- Prevents Shaft Damage: Protects the shaft threads from damage by ensuring the lock nut does not move.
- Simple and Accessible: A globally recognized standard, making it easy to source and replace.
