Product Overview: The MB 19 Lock Washer
The MB 19 is a high-quality lock washer, an essential component within our Bearing Accessories collection, designed to securely fasten bearings onto a shaft or adapter sleeve. With a bore diameter of 95mm, an outer diameter of 130mm, and a thickness of 2.0mm, this washer is specifically engineered for use with a corresponding KM 19 lock nut. Its primary function is to prevent the lock nut from loosening due to vibration or operational stresses, ensuring the bearing assembly remains tight and correctly positioned.
As a key part of the Lock Washer family, the MB 19 features an inner tab that locates in the keyway of the shaft or adapter sleeve and multiple outer tabs. Once the lock nut is tightened, one of the outer tabs is bent into a corresponding slot on the circumference of the nut, creating a positive lock. This simple yet effective mechanism provides a reliable and secure mounting solution for a wide range of industrial applications.
Key Features of the MB 19
- Positive Locking Mechanism: Employs a tab-locking design to physically prevent the lock nut from rotating and loosening.
- Precision Engineered: Manufactured to precise dimensional tolerances to ensure a perfect fit with KM 19 lock nuts and associated components.
- Durable Construction: Made from high-strength steel to withstand the forces of installation and resist operational stresses.
- Vibration Resistance: An effective solution for securing bearings in machinery prone to high levels of vibration.
- Simple Installation: Easy to install and secure with basic hand tools, providing a straightforward mounting process.
- Reusable: The washer can often be reused if the tabs are carefully bent back, though replacement is recommended for critical applications.
Common Applications
- Industrial Gearboxes: Secures bearings on input and output shafts, preventing axial movement and maintaining gear alignment.
- Conveyor Systems: Used on conveyor rollers and pulleys to ensure bearings remain tightly fastened during continuous operation.
- Pumps and Compressors: Provides a secure mounting for bearings on rotating shafts in fluid and air handling equipment.
- Electric Motors and Generators: Essential for locking rotor shaft bearings in place, ensuring smooth and reliable rotation.
- Agricultural Machinery: Widely used in equipment such as combines, tractors, and balers to withstand harsh operating conditions.
- Mining and Construction Equipment: Secures bearings in heavy-duty machinery where vibration and shock loads are common.
- Fans and Blowers: Prevents lock nuts from backing off on high-speed fan shafts, enhancing safety and reliability.
Benefits of Using the MB 19 Lock Washer
- Enhanced Operational Safety: Prevents catastrophic failure that could result from a bearing coming loose on a shaft.
- Improved Machine Reliability: Ensures components remain securely mounted, reducing downtime and maintenance intervals.
- Extended Bearing Life: By maintaining the correct preload and position, it prevents premature bearing wear and damage.
- Cost-Effective Solution: A simple and inexpensive method for providing a highly reliable and secure bearing assembly.
- Easy to Inspect: The bent tab provides a clear visual confirmation that the assembly is properly locked.
- Maintains Assembly Integrity: Guarantees that the axial clamping force provided by the lock nut is consistently maintained over time.
