We propose improvements for issues such as rotational unevenness, vibration, and noise! Introducing our constant velocity joints.
Traditionally, universal joints and couplings have been the mainstream choices for industrial joints. Universal joints, also known as cross joints, are characterized by their ability to accommodate large operating angles (up to 30 degrees). Additionally, the cross mechanism reduces backlash. However, for high-angle rotations, the motion involves a rapid-slow-rapid-slow rotation within one complete turn, which can lead to issues such as rotational irregularities, vibrations, or noise. To address such issues, we propose the use of constant velocity joints. **Features of Constant Velocity Joints** - Reduction of vibration and noise due to smooth constant rotation - Increased product accuracy through constant rotation (eliminating secondary processing) - Shortened alignment work time (reducing labor costs) - Compact constant velocity joints with a large allowable expansion, making installation easy - Due to the ball joint design, they have a longer lifespan and strength compared to universal joints of the same size (excellent strength, durability, and high reliability) *For more details, please refer to the PDF document or feel free to contact us.*

Since its establishment in 1964, our company has been dedicated solely to the manufacturing of metal products. We consist of three divisions centered around automotive constant velocity joints: (1) automotive constant velocity joints, (2) industrial constant velocity joints, and (3) precision machining. By leveraging the strengths of each division, we create proposal-based products that meet our customers' needs, with all processes from design and manufacturing to shipping managed in-house. We handle over approximately 5,000 types of products, including constant velocity joints.
