Product Overview: The MB 20 Lock Washer
The MB 20 is a precision-engineered lock washer, an essential component in our Bearing Accessories collection. With a bore of 100mm, an outer diameter of 132mm, and a thickness of 1.25mm, it is specifically designed to be used with a KM 20 lock nut to secure bearings onto a shaft. This washer prevents the lock nut from loosening due to vibration or operational torque, ensuring the entire bearing assembly remains tight and correctly positioned. Its simple yet effective design, featuring multiple locking tabs, makes it a reliable choice for a vast range of industrial applications.
As a key part of securing tapered bore bearings with adapter sleeves, the MB 20 Lock Washer is fundamental for machine reliability and safety. By bending one of its tabs into a slot on the lock nut, it creates a secure mechanical lock that is both easy to install and inspect. Trust our high-quality lock washers to maintain the integrity of your machinery's rotating components.
Key Features of the MB 20 Lock Washer
- Precision Fit: Manufactured to strict tolerances to ensure a perfect match with KM 20 lock nuts and corresponding shafts.
- Secure Locking Mechanism: Features an inner tab that locates in the shaft's keyway and outer tabs that bend into the nut's slots to prevent rotation.
- Durable Material: Constructed from high-quality spring steel for excellent strength, resilience, and long service life.
- Vibration Resistance: Effectively prevents the lock nut from backing off, even in high-vibration environments.
- Ease of Installation: Simple to fit and secure using basic hand tools, reducing assembly time and effort.
- Corrosion Resistant: Typically treated with a protective finish to resist rust and environmental wear.
Common Applications
- Industrial Gearboxes: Secures gears and bearings on shafts, preventing axial movement and loosening.
- Conveyor Systems: Used in pulley and roller assemblies to ensure bearings remain securely fastened.
- Pumps and Compressors: Maintains the correct positioning of bearings on rotating shafts for optimal performance.
- Electric Motors: Secures rotor bearings, contributing to the motor's reliability and longevity.
- Agricultural Machinery: Essential for implements and vehicles where vibration and heavy loads are common.
- Mining and Construction Equipment: Provides a robust locking solution for heavy-duty machinery operating in harsh conditions.
- Fan and Blower Units: Ensures that bearing assemblies on fan shafts remain secure for safe and efficient operation.
Benefits of Using the MB 20 Lock Washer
- Enhanced Operational Safety: Prevents catastrophic failure by ensuring critical components do not come loose during operation.
- Increased Machine Reliability: Provides a dependable method for securing bearings, reducing downtime and maintenance interruptions.
- Cost-Effective Solution: An inexpensive yet crucial component that protects more valuable parts like bearings, shafts, and housings.
- Simplified Maintenance: While secure, the washer can be unbent and replaced, allowing for straightforward disassembly when required.
- Extended Component Life: By maintaining proper bearing preload and position, it helps extend the service life of the entire assembly.
- Positive Locking Action: Offers a tangible, physical lock that is more secure than friction-based locking methods alone.
