High-Speed Precision Universal Joint for Demanding Motion Control Applications

In applications requiring accurate angular power transmission with minimal backlash and high rotational speeds, a reliable precision universal joint is indispensable. Apexcoupling specializes in manufacturing the HR and GR series precision universal joint, engineered to deliver exceptional performance in automated machinery and precision drives. This professional precision universal joint is available in two distinct designs: the HR series featuring integrated needle bearings for ultra-high-speed operation up to 4000 RPM, and the GR series with a robust pin-and-block structure for high-torque applications up to 1000 RPM. Each precision universal joint is machined to tight tolerances, ensuring small internal clearance for smooth, quiet operation and an extended service life, making it a cornerstone component for system reliability.

The core advantage of this precision universal joint lies in its quick-clamping design, which allows for rapid engagement and disengagement without tools, facilitating easy maintenance and shaft connection. Engineered for connecting shafts on the same plane, this precision universal joint accommodates a maximum single-joint articulation angle of 45 degrees, with a recommended continuous working angle of up to 30 degrees for optimal durability. The clamping hub of this precision universal joint is supplied with an H7 precision tolerance bore, offering a standard keyway per DIN 6885/1-JS9 or a hexagonal bore option, ensuring a secure, slip-free fit on the shaft. We manufacture this versatile precision universal joint from 40Cr high-carbon steel as standard, with full customization available for materials like 304/316 stainless steel and various surface finishes including blackening, chrome/nickel plating, and sandblasting to meet specific OEM requirements and environmental conditions.
