1.Product Material & Production Technology

Main Body Casting Craft

The balance suspension equalizer beam adopts high toughness ductile nodular cast iron as raw material. Adopt lost foam casting integral forming technology; the internal metal grain is compact and uniform, effectively resisting heavy impact load, avoiding fracture and deformation under long-term full-load transportation. The blank undergoes multiple rough & finish CNC machining to guarantee precise OEM dimensional tolerance.

Surface Anti-Corrosion Treatment

Double anti-rust process of shot blasting + electrostatic spraying. Shot blasting removes casting oxide skin to enhance coating adhesion; thick uniform anti-rust paint layer isolates mud, rainwater and saline corrosion, suitable for mining, construction and coastal transport scenarios.

Bushing Integrated Assembly Process

Equipped with high wear-resistant oil-filled steel rubber bushing. The bushing inner sleeve is quenched for high hardness, outer rubber uses anti-aging oil-resistant formula, integrated vulcanization bonding without degumming. Independent grease injection channel design allows regular lubrication to extend service life greatly.

Precision Matching Calibration

All assembly holes, pin shafts and connecting brackets are processed strictly in accordance with original vehicle drawing standards. Complete inspection of flatness, aperture and assembly clearance before delivery to ensure zero modification during installation.

2.Core Product Advantages

Uniform Axle Load Distribution

Walking beam balance structure automatically distributes weight on multi-axle vehicles, avoids single axle overload, effectively reduces uneven tire wear and prolongs tire service cycle.

Strong Impact & Fatigue Resistance

Ductile cast iron main beam with stable mechanical performance, withstands frequent bumping on rough muddy roads, no cracking after long-term heavy-load operation, low maintenance frequency.

Good Shock Absorption & Stable Driving

Lubricated elastic bushings buffer chassis vibration during driving, improve vehicle straight-line stability, reduce swing of dump trucks and semi-trailers when climbing or braking.

Wide Compatibility & Easy Replacement

Complete OEM standard size assembly kit, plug-and-play without cutting or grinding. Compatible with Sinotruk Howo, Shacman, FAW, Dongfeng, Volvo, MAN, BPW, SAF, FUWA semi-trailer axles.

3.Application & Supply Information

Widely used on tandem-axle heavy trucks, dump trucks, tractors and multi-axle semi-trailers for mining, logistics and engineering transportation. Factory direct wholesale, support OE number customized production, sufficient stock and fast global delivery for auto spare parts distributors and repair workshops.
