Product Introduction

Structure

This double universal joint is a precision-engineered two-stage Cardan joint assembly, constructed from high-strength forged steel. It features two integrated universal joints connected by a central yoke and cross-bearing assembly, with each joint terminating in a fork with precision-machined mounting holes for connection to the steering linkage. The entire assembly is coated with a matte gray anti-corrosion finish, and the cross-bearings are fitted with high-performance seals to retain lubrication and prevent contamination. The dual-joint design allows for angular misalignment in multiple planes, ensuring smooth torque transmission.

Performance

The forged steel construction provides exceptional strength and durability, capable of withstanding the torsional loads and stresses of heavy-duty truck steering systems. The cross-bearings are precision-ground and fitted with multi-lip seals, ensuring reliable lubrication and resistance to wear in temperatures ranging from -40°C to 120°C. The anti-corrosion coating offers superior resistance to rust, salt spray, and chemical corrosion, ensuring consistent performance in diverse operating conditions.

Core Function

1. Transmits steering torque between non-collinear shafts in the steering linkage, accommodating angular misalignment to ensure smooth and responsive steering input transmission.

2. Maintains constant velocity torque transmission, eliminating vibration and ensuring precise control of the vehicle’s direction.

3. Absorbs and dampens minor shocks and vibrations from the steering linkage, protecting the steering gear and column from premature wear and fatigue.

Key Features and Benefits of Double Universal Joint 711W46122-0080

This isn’t just another universal joint — it’s a precision-engineered drivetrain component built to handle the demanding conditions that Sitrak trucks face daily. Here’s what sets it apart:

• Accurate Power Transmission: The double universal joint smoothly transfers rotational force between shafts, even when they’re not perfectly aligned. This means consistent steering response and reduced mechanical stress on surrounding components.
• Angular Deviation Compensation: Designed with dual cross-bearing assemblies, this joint compensates for angular offsets between the input and output shafts. As a result, it absorbs vibrations and prevents premature wear on the steering column.
• Heavy-Duty Construction: Manufactured from high-strength alloy steel with precision-ground bearing surfaces, this part withstands the intense loads and harsh operating environments typical of heavy commercial vehicles.
• OEM-Spec Fitment: Part number 711W46122-0080 is designed as a direct replacement for the original Sinotruk Sitrak component. No modifications needed — it bolts right in.
• Extended Service Life: Heat-treated bearing cups and high-quality needle roller bearings ensure long-lasting performance, reducing your maintenance frequency and total cost of ownership.
• Corrosion Resistance: Surface treatment protects against rust and environmental degradation, which is especially important for trucks operating in humid or coastal regions.

Frequently Asked Questions About Double Universal Joint 711W46122-0080

What is the function of a double universal joint in a Sitrak truck?

A double universal joint connects two shafts at an angle and transmits rotational torque between them. In Sitrak trucks, it’s installed on the steering intermediate shaft to transfer your steering input to the steering gear. The “double” design uses two cross-bearing assemblies, which allows it to compensate for greater angular misalignment and deliver smoother, more constant-velocity power transmission compared to a single universal joint.

How do I know if my double universal joint needs replacement?

Several symptoms indicate a worn or failing double universal joint. Watch for excessive play or looseness in the steering wheel, clunking or knocking noises when turning, vibrations felt through the steering column, or uneven steering response. If you notice any of these signs, inspect the joint for worn bearings, cracked yokes, or excessive radial play. Replacing it promptly prevents further damage to the steering system.

Is part number 711W46122-0080 an exact OEM replacement?

Yes. This double universal joint is manufactured to match the original Sinotruk specifications for part number 711W46122-0080. It shares identical dimensions, bearing specifications, and spline configurations with the factory-installed component. Installation requires no modifications — it’s a direct bolt-on replacement.

What’s the difference between a single and double universal joint?

A single universal joint has one cross-bearing assembly and introduces slight speed variation (non-constant velocity) during rotation at an angle. A double universal joint uses two cross-bearing assemblies connected by an intermediate yoke, which cancels out these speed fluctuations. This makes the double joint ideal for steering applications where smooth, consistent motion is critical for driver control and comfort.

How should I maintain the double universal joint to extend its lifespan?

Regular lubrication is the most important maintenance step. Apply grease to the bearing cups at recommended service intervals to prevent dry friction and premature wear. Additionally, inspect the joint periodically for signs of seal damage, contamination ingress, or bearing looseness. Keeping the protective boots intact prevents dirt and moisture from reaching the needle bearings inside.

Can this part be used on other Sinotruk models besides Sitrak?

Part number 711W46122-0080 is specifically designed for Sitrak series trucks. While some Sinotruk models share similar steering architectures, cross-compatibility depends on the exact spline count, shaft diameter, and mounting configuration. We recommend verifying the OEM part number against your vehicle’s parts catalog before ordering. If you’re unsure, our team can help you confirm fitment.
