Product Overview: The MB 32 Lock Washer
The MB 32 Lock Washer is an essential component designed to securely fasten bearings onto a shaft or adapter sleeve. With a bore diameter of 160 mm, an outer diameter of 215 mm, and a thickness of 2.5 mm, this washer is precision-engineered to work in tandem with a corresponding KM 32 lock nut. As a vital part of our Bearing Accessories and Lock Washer collections, the MB 32 prevents the loosening of bearings caused by vibration or operational torque, ensuring machine reliability and safety.
This type of washer features multiple tabs around its outer circumference. One of the inner tabs is designed to locate in a keyway on the shaft or sleeve, while one of the outer tabs is bent into a slot on the lock nut to provide a secure mechanical lock. This simple yet effective design is a standard solution in a vast range of industrial applications for mounting tapered bore bearings.
Key Features of the MB 32 Lock Washer
- Secure Locking Mechanism: Utilizes a tab-locking system to prevent the associated lock nut from rotating and loosening.
- Durable Construction: Manufactured from high-quality steel to withstand operational stresses and ensure long-term performance.
- Precision Dimensions: Engineered to exact specifications (160x215x2.5mm) for a perfect fit with KM 32 lock nuts and corresponding shafts.
- Vibration Resistance: Provides a reliable mechanical lock that is highly effective in applications with significant vibration.
- Simple Installation: Easy to install and secure, requiring only basic tools to bend the locking tab into place.
- Reusable Design: Can often be carefully unbent and reused during maintenance, offering a cost-effective solution.
Common Applications
- Bearing Assemblies: Used to secure bearings on both straight shafts (with adapter sleeves) and stepped shafts.
- Industrial Gearboxes: Ensures that gears and bearings remain tightly secured on their shafts, preventing misalignment.
- Conveyor Belt Pulleys: Locks pulley bearings in place, which is critical for the reliable operation of conveyor systems.
- Electric Motors and Pumps: Prevents nuts from backing off on motor shafts and pump impellers.
- Agricultural Machinery: Widely used in equipment such as combines, tractors, and balers to secure components exposed to high vibration.
- Mining and Construction Equipment: Essential for heavy-duty machinery where component security is paramount for safety and function.
Benefits of Using the MB 32 Lock Washer
- Enhanced Operational Safety: Prevents catastrophic failures that can result from a bearing coming loose on a rotating shaft.
- Increased Machine Uptime: By providing a reliable fastening method, it reduces the likelihood of unscheduled maintenance and downtime.
- Extended Component Life: Protects the bearing, shaft, and housing from damage caused by loosening and subsequent movement.
- Cost-Effective Security: An inexpensive and highly effective method for securing critical rotating components.
- Ease of Use: Simplifies the assembly process for tapered bore bearings, ensuring they are correctly positioned and secured.
- Positive Locking Action: Offers a clear visual confirmation that the assembly is properly locked, unlike friction-based locking methods.
