When it comes to precision and durability in mechanical systems, GUM Universal-Joints stand out as a trusted solution for various applications. These joints, also known as universal couplings or U-joints, are essential components that allow for the transmission of rotational motion between shafts that are not aligned. Our GUM Universal-Joints are engineered with high-quality materials and advanced manufacturing processes to ensure reliability, efficiency, and longevity in demanding environments. Whether you're in automotive, industrial machinery, agriculture, or aerospace, our products deliver superior performance.
GUM Universal-Joints are designed to accommodate angular misalignment, parallel offset, and even axial movement in some models. They are ideal for use in driveshafts, steering systems, and other mechanisms where flexibility is required. With a focus on innovation and customer satisfaction, we offer a wide range of universal joints tailored to meet specific needs, including standard series, heavy-duty options, and custom designs.
Below is a comprehensive table outlining the specifications for our popular GUM Universal-Joints series. These parameters help in selecting the right joint for your application based on size, load capacity, and other critical factors.

In addition to these standard models, we provide custom universal joints with bespoke parameters. For instance, special coatings for extreme environments or unique sizes to fit specific machinery. Our technical team can assist in designing joints that meet exact requirements, ensuring optimal performance.
What is a universal joint and how does it work?
A universal joint is a mechanical device that connects two shafts at an angle, allowing for the transmission of rotary motion. It consists of a cross-shaped pivot with bearings at each end, which enables flexibility and compensates for misalignment between shafts.
What materials are used in GUM Universal-Joints?
Our joints are manufactured from high-strength materials such as carbon steel, stainless steel, alloy steel, and titanium, depending on the series. These materials are chosen for their durability, resistance to wear, and ability to handle high loads and harsh conditions.
How do I select the right GUM Universal-Joint for my application?
Consider factors like torque requirements, operating speed, shaft size, environmental conditions (e.g., temperature, exposure to chemicals), and the type of misalignment (angular, parallel, or axial). Refer to our product table above or consult with our engineers for personalized recommendations.
Are GUM Universal-Joints easy to install and maintain?
Yes, they are designed for straightforward installation with standard tools. Maintenance typically involves periodic lubrication of the bearing points, and many models come with sealed units that reduce the need for frequent servicing. Always follow the manufacturer's guidelines for upkeep.
Can GUM Universal-Joints be used in high-speed applications?
Absolutely. Our joints are tested for high RPM operations, with some models supporting speeds up to 5000 RPM. However, it's crucial to match the joint to the application's speed and load to prevent premature failure. Check the max speed rating in the product specifications.
What is the lifespan of a GUM Universal-Joint?
Lifespan varies based on usage, load, and maintenance. Under normal conditions, our joints can last for thousands of hours of operation. Regular inspection and proper lubrication can extend their life significantly. For specific estimates, provide details of your application to our support team.
Do you offer custom universal joints?
Yes, we provide custom design services to create universal joints that meet unique specifications, such as special sizes, materials, or performance characteristics. Contact us with your requirements, and we'll develop a solution tailored to your needs.
How does temperature affect the performance of GUM Universal-Joints?
Our joints are rated for a broad temperature range (-40°C to 120°C). Extreme temperatures can impact lubrication and material properties, so for applications outside this range, we recommend selecting models with appropriate materials and coatings or consulting our experts for advice.
What are the signs that a universal joint needs replacement?
Common indicators include unusual noises (e.g., clicking or grinding), vibration during operation, visible wear or corrosion, and difficulty in transmitting power. Regular inspections can help detect issues early, preventing downtime and damage to other components.
Are GUM Universal-Joints compatible with international standards?
Yes, our products comply with relevant international standards such as ISO 9001 for quality management and specific industry norms. This ensures reliability and interoperability in global markets.
