Product Introduction

Structure

This balance shaft bracket is a precision-cast ductile iron component, featuring a robust U-shaped design optimized for heavy-duty truck chassis integration. The main body is a rib-reinforced casting, with a central cylindrical bore for balance shaft mounting and two side mounting lugs with precision-machined holes for chassis attachment. The entire assembly is finished with a matte gray anti-corrosion coating, and a label with the part number “WG9100520034” is affixed for easy identification.

Performance

Constructed from high-grade ductile iron, the bracket offers exceptional structural rigidity, impact resistance, and fatigue strength, capable of withstanding the extreme loads and stresses encountered in heavy-duty operation. The precision-machined mounting holes ensure accurate alignment and secure attachment of the balance shaft and associated components, while the rib-reinforced design optimizes load distribution, preventing localized stress concentrations and component failure. The anti-corrosion coating provides superior resistance to rust, salt spray, and chemical corrosion, ensuring long-term durability in diverse operating conditions, with a temperature range of -40°C to 120°C.

Core Function

1. Serves as a critical mounting interface for the balance shaft, providing a secure and stable attachment point to the chassis, ensuring proper alignment and load distribution.

2. Transmits and distributes complex loads such as vertical pressure, lateral torque, and longitudinal impact from the balance shaft to the chassis, maintaining the integrity of the suspension system.

Maintains precise alignment of the balance shaft and associated components, preventing relative displacement under dynamic conditions such as vehicle acceleration, braking, and turning, avoiding abnormal wear of suspension parts

Frequently Asked Questions (FAQ)

What does the balance shaft bracket WG9100520034 actually do?

This bracket acts as the structural anchor for the balance shaft in Sinotruk HOWO trucks. It holds the balance shaft firmly in position on the chassis frame, allowing the shaft to equalize load distribution between the two rear axles. Without a properly functioning bracket, the balance shaft can shift or vibrate excessively, leading to uneven tire wear and compromised ride stability.

How do I know if my balance shaft bracket needs replacement?

Common signs include visible cracks or fractures on the bracket body, excessive play or movement in the balance shaft area, unusual clunking noises from the rear suspension during driving, and uneven wear patterns on rear tires. Additionally, if your truck has accumulated high mileage under heavy loads, preventive inspection of this bracket is strongly recommended.

Is this WG9100520034 bracket a direct fit for all HOWO models?

This part is designed for Sinotruk HOWO heavy trucks with standard tandem rear axle configurations. However, since HOWO covers multiple generations and variants, we recommend confirming your truck’s VIN or chassis number with our team to ensure exact compatibility before ordering.

What material is the balance shaft bracket made from, and how durable is it?

The WG9100520034 bracket is cast from high-strength alloy steel, which provides excellent resistance to fatigue, impact, and deformation under heavy loads. Furthermore, the anti-corrosion surface treatment protects it from environmental degradation, making it suitable for trucks operating in diverse climates.

Can I order this bracket with my own brand packaging?

Absolutely. Mettlead offers both neutral (white-label) packaging and fully customized packaging solutions. This is particularly useful for distributors and resellers who want to maintain brand consistency across their product lines.

What is the typical lead time for this part?

Lead times depend on order quantity and current stock levels. For standard orders, we typically ship within a few business days. Larger bulk orders may require slightly longer production time. Please contact us for a precise delivery estimate based on your requirements.
