Precision Customization, We Deliver What We Promise

Just share your drawings and specifications with us — we’ll bring them to life with precision. Every universal joint is produced exactly to your requirements, ensuring stable performance and dependable quality.

Tough and Durable, Built to Last

We use high-grade alloy steel as the base material, with core cross shafts treated through advanced carburizing processes. This gives our products exceptional wear resistance, fatigue strength, and long service life — ready to perform under even the harshest conditions.

Fast Delivery, No Delays

With an efficient supply chain and optimized production management, we respond quickly to every order, ensuring on-time delivery and helping you stay ahead in the market.

Flexible Cooperation, Supporting Innovation

Whether you’re in the prototyping stage or require large-scale production, we adapt to your needs seamlessly. We’re also eager to support custom product development and performance upgrades based on your existing designs.

Competitive Pricing, Greater Value in Volume

Through large-scale production and continuous process optimization, we maintain top quality while keeping costs low — offering highly competitive prices, especially for bulk orders that deliver the best value for your business.

To ensure the long-term durability and stable performance of the universal joint, regular inspection and maintenance are essential. We recommend the following: 

Regular Lubrication:

Follow the product specifications strictly and use high-quality grease of the designated grade for periodic lubrication. Proper lubrication effectively reduces internal wear, lowers operating temperature, and extends service life.

Routine Inspection:

Regularly check for oil leakage, abnormal noise, radial runout, or unusual vibration. Inspect the spline section for signs of rust or dust accumulation, and clean it promptly if necessary.

Cleaning and Protection:

Keep the universal joint clean at all times. Under harsh operating conditions, remove mud, gravel, or other debris attached to the surface to prevent contamination or damage to the seals.

Our universal joints are manufactured with advanced precision processes to meet the highest quality standards: 

Precision Forging:

The main components are forged from high-quality alloy steel to ensure continuous metal flow lines and dense microstructure, providing superior base strength and fatigue life.

Heat Treatment:

Core components, such as the cross shaft, undergo advanced heat treatment processes including carburizing, quenching, and tempering. This achieves a high surface hardness for wear resistance while maintaining a tough and ductile core to withstand impact loads.

Precision Grinding and Dynamic Balancing:

Key mating surfaces, such as bearing journals, are ground with high precision to ensure dimensional accuracy and proper fit clearance. After assembly, each unit undergoes rigorous dynamic balance testing to guarantee smooth high-speed operation with minimal vibration and noise.

To prevent damage caused by improper use, please observe the following precautions:

Avoid Overloading:

Do not operate beyond the rated torque or speed of the product. Overloading can dramatically shorten service life and may result in sudden fracture.

Proper Installation:

Ensure correct alignment between the connected components during installation. Avoid excessive force or hammering. Tighten all bolts to the specified torque and always use new locking components such as cotter pins.

Regular Replacement:

As a wear component, the universal joint should be inspected periodically according to the equipment maintenance schedule. If noticeable clearance, abnormal noise, or stiffness occurs, stop operation immediately and replace the unit to prevent secondary damage.

Do you support prototyping and small-batch production for new projects?

Absolutely. We are glad to support customers in new product development. We offer flexible small-batch customization services for sample validation, testing, and pilot production — ensuring a smooth transition from design to mass production.

What is your production process if we provide our own design drawings?

Once we receive your drawings, our technical team will quickly evaluate them and provide a feasibility analysis along with a quotation. Upon order confirmation, we will manufacture strictly according to your specifications and keep you updated at key production stages to ensure the final product fully meets your design requirements.

What is your minimum order quantity (MOQ)?

As an OEM manufacturer, we are highly flexible and have no strict MOQ requirement. We understand that each project has different needs — from small quantities for prototype testing to large-scale production orders — and we can adjust accordingly to support your specific requirements.

Do bulk orders come with price or lead-time advantages?

Yes, that’s one of our key strengths. Through large-scale production and optimized scheduling, bulk orders benefit from more competitive unit prices and faster, more stable delivery timelines.

Can you help improve or redesign our existing products?

Yes, we can. We are not only a manufacturer but also your technical partner. With years of expertise in universal joint engineering, we can provide material, process, or structural optimization suggestions to enhance performance, extend service life, or reduce costs.

If you have more specific questions, please feel free to contact us — our team will be happy to provide a tailored solution for your needs.
