Product Overview: The MB 29 Lock Washer
The MB 29 is a crucial component in our range of Bearing Accessories, designed to secure bearing assemblies on shafts. As a high-quality Lock Washer, its primary function is to lock a KM 29 lock nut in place, preventing it from loosening due to vibration or operational torque. With an inner diameter of 145mm, an outer diameter of 192mm, and a thickness of 2.5mm, the MB 29 is manufactured to precise DIN 5406 standards to ensure a perfect fit and reliable performance. It is an essential part for mounting bearings with tapered bores using adapter or withdrawal sleeves.
Key Features of the MB 29
- Secure Locking Mechanism: Features multiple external tabs that can be bent into the slots of a lock nut, providing a secure mechanical lock.
- Prevents Loosening: Effectively counteracts the effects of vibration and dynamic loads, ensuring the lock nut remains tight.
- Durable Construction: Made from high-quality spring steel for excellent strength, durability, and resistance to deformation.
- Precision Engineered: Manufactured to strict industry standards for consistent dimensions and a reliable fit with corresponding KM 29 lock nuts.
- Simple Installation: Easy to install and secure, requiring only simple hand tools to bend the locking tab into place.
- Corrosion Resistant: Often treated with a surface finish to protect against rust and environmental corrosion, extending its service life.
Common Applications
- Industrial Gearboxes: Secures bearings on input and output shafts, maintaining critical gear alignment.
- Conveyor Belt Pulleys: Ensures pulley bearings remain tightly fixed on their shafts despite constant rotation and load.
- Large Fans and Blowers: Prevents bearing nuts from backing off in high-vibration environments.
- Pumps and Compressors: Maintains the integrity of rotating assemblies by securing bearings on shafts.
- Agricultural Machinery: Used in demanding applications like harvesters and tractors where components are subject to shock and vibration.
- Mining and Construction Equipment: Provides reliable fastening for bearings in heavy-duty machinery operating in harsh conditions.
Benefits of Using the MB 29
- Enhanced Reliability: Guarantees that the pre-set bearing clearance and preload are maintained, leading to more reliable machine operation.
- Increased Safety: Prevents catastrophic failure that could result from a loosened bearing nut in a critical application.
- Reduced Maintenance: A simple, cost-effective method to avoid frequent re-tightening of lock nuts, reducing downtime and labor costs.
- Extended Component Life: By ensuring the bearing assembly remains secure, it reduces wear on the bearing, shaft, and housing.
- Cost-Effective Solution: Offers a proven and inexpensive method for securing critical components compared to more complex locking systems.
