Engineering and Configuration Approach
We configure each U-joint bearing based on the working point: shaft diameter, operating angle, torque, speed, and lubrication method. Our engineers review the application to recommend the correct cross-shaft material, heat treatment, and needle roller complement.
- Material selection: chrome steel or stainless steel for corrosion resistance
- Heat treatment: controlled case depth for wear resistance
- Sealing options: open, shielded, or sealed with grease
- Custom dimensions and mounting features
Quality Assurance and Testing
We operate a QC system that inspects after each manufacturing process. Finished U-joint bearings undergo dimensional checks, hardness testing, and rotational accuracy verification. For critical applications, we can perform full inspection according to customer specifications and international standards.
Our factory in Jiangsu is equipped with modern production machinery and precision measuring tools. We maintain traceability from raw material to final assembly.
Integration and Support
We support direct integration into your driveshaft assembly or as a replacement part. Our team provides installation guidance, torque specifications, and maintenance recommendations. For high-volume programs, we coordinate packaging and logistics to your production schedule.
We also offer training for distributors and agents on product selection and handling.
Information We Use to Configure Your Solution
To prepare a precise quotation and engineering proposal, we need the following project information:
- Application type (vehicle model, equipment, or system)
- Operating torque, speed, and maximum working angle
- Shaft and bore dimensions, or existing part number
- Required service life and environmental conditions
- Lubrication and sealing preferences
- Annual volume and target delivery schedule
With this data, we can recommend the correct U-joint bearing configuration and provide samples for validation.

Frequently Asked Questions
What is a U-joint bearing and where is it used?
A U-joint bearing, also known as a universal joint bearing, is a component that allows a driveshaft to transmit torque at varying angles. It is commonly used in automotive driveshafts, steering systems, and industrial PTO applications.
Can you supply custom U-joint bearings?
Yes, we can manufacture U-joint bearings to custom dimensions and specifications. We work with your drawings or samples to produce a bearing that fits your application.
What is the minimum order quantity?
Our standard MOQ is 100 sets for many bearing types. For U-joint bearings, we can discuss lower quantities for sample testing or pilot runs.
How do you ensure quality consistency?
We conduct inspections after each production step and perform final inspection on finished products. Our QC system follows international standards and can be adapted to your specific requirements.
What is your typical lead time?
For in-stock items, we can ship within 3 working days. For custom or large orders, lead time depends on the complexity and volume; we provide a confirmed schedule with your quotation.
