Product Introduction

The 6243250112 Suspension Saddle Trunnion Seat is one of the key structural components in the rear tandem bogie suspension system of Mercedes-Benz SK series and Beiben NG80 heavy-duty trucks.

Installed between the vehicle chassis and the balance shaft assembly, the saddle trunnion seat serves as the mounting base for the balance shaft. It allows the equalizer beam to pivot smoothly while evenly distributing vehicle weight across the tandem rear axles, improving suspension flexibility, ride comfort, and overall vehicle stability.

The suspension saddle works together with:

• Balance shaft
• Equalizer beam
• Suspension console bracket
• Bronze bushings
• Oil seals
• Leaf spring assembly
• Rear axle housing
• Mounting bolts

Its primary functions include:

• Supporting the balance shaft assembly
• Providing a stable pivot point for the equalizer beam
• Distributing axle loads evenly
• Reducing chassis stress
• Improving suspension durability and ride stability

Under heavy-load transportation, mining, construction, and off-road operating conditions, the suspension saddle is subjected to continuous shock loads, vibration, and axle articulation. A worn or damaged saddle seat may result in:

• Suspension misalignment
• Excessive balance shaft movement
• Uneven axle load distribution
• Accelerated bushing wear
• Suspension noise
• Reduced vehicle stability

The 6243250112 balance shaft seat is manufactured from premium high-strength structural steel using precision casting, CNC machining, and anti-corrosion surface treatment. All bearing surfaces and mounting holes are produced to OEM tolerances to ensure accurate installation, smooth suspension movement, and long service life.

Designed according to OEM specifications, this component provides direct replacement compatibility for Mercedes-Benz SK series and Beiben NG80 rear bogie suspension systems. It is widely used for suspension rebuilding, fleet maintenance, mining trucks, construction vehicles, and heavy commercial transportation. Industry references describe OEM 6243250112 as a suspension saddle/trunnion seat used in Mercedes-Benz suspension assemblies.

Each suspension saddle undergoes strict quality inspections including:

• Material strength testing
• Dimensional accuracy inspection
• Bearing housing measurement
• Mounting hole position verification
• Surface coating inspection
• Installation fitment testing

to ensure OEM-level reliability and durability.
