Product Overview: The MB 07 Lock Washer
The MB 07 Lock Washer is an essential fastening component designed to secure bearings on a shaft when used in conjunction with a corresponding KM 07 lock nut. With an inner diameter of 35mm, an outer diameter of 48mm, and a thickness of 1mm, this washer is engineered to prevent the loosening of the lock nut, which can occur due to vibration or operational stresses. It is a critical part of our Bearing Accessories and Lock Washer collections, providing a simple yet highly effective method for maintaining the integrity of bearing assemblies.
The MB 07 features multiple tabs around its circumference. One inner tab is designed to locate in a keyway or slot on the shaft, preventing the washer itself from rotating. After the lock nut is tightened to the correct torque, one of the outer tabs is bent into a corresponding slot on the lock nut, effectively locking the nut in place. This positive locking mechanism ensures that the bearing assembly remains securely mounted, enhancing both the safety and reliability of the machinery.
Key Features of the MB 07 Lock Washer
- Positive Locking: Utilizes a tab-bending mechanism to securely lock the nut in position, preventing rotational loosening.
- Vibration Resistance: Specifically designed to maintain fastening integrity in applications with high levels of vibration.
- Standardized Sizing: Manufactured to industry-standard dimensions for direct compatibility with KM 07 lock nuts and bearings with a 35mm bore.
- Durable Construction: Made from high-quality steel to provide the strength and resilience needed for secure fastening.
- Simple Installation: Can be easily installed and secured using common hand tools.
- Cost-Effective Security: Offers a reliable and economical solution for securing critical bearing arrangements.
Common Applications
- Electric Motors and Pumps: Secures bearings on motor shafts, ensuring long-term operational stability.
- Industrial Gearboxes: Prevents bearing nuts from loosening within gear assemblies, where vibration is common.
- Conveyor Belt Rollers: Maintains the position of bearings in conveyor systems, critical for continuous operation.
- Agricultural Machinery: Used in equipment like tillers and harvesters to secure components against harsh operational conditions.
- Fans and Blowers: Ensures that bearing assemblies in industrial fans remain tight and secure.
- Automotive Drivetrains: Applied in various shaft assemblies to lock retaining nuts in place.
- Mining and Construction Equipment: Provides a robust locking solution for heavy-duty machinery.
Benefits of Using the MB 07 Lock Washer
- Enhanced Machine Reliability: Guarantees that the bearing's axial position is maintained, reducing the risk of unexpected downtime.
- Improved Safety: Prevents the catastrophic failure that can result from a loosened lock nut and dismounted bearing.
- Reduced Maintenance Costs: Creates a secure, set-and-forget assembly that eliminates the need for periodic re-tightening.
- Easy to Use: Its straightforward design simplifies the process of mounting and securing bearings.
- Versatile Compatibility: Works seamlessly with KM series lock nuts and is suitable for use on straight shafts or with adapter sleeves like the H 207.
- Prolonged Component Life: By ensuring the bearing is properly secured, it helps to extend the service life of both the bearing and the shaft.
