Single Joint

ZA & ZD Series

A precision u-joint consists of a pair of hinges, oriented 90° to each other and connected by a cross shaft. These specialty couplings, also known as U-joints or universal couplings, are installed in rigid shafts or rods and allow those shafts to “bend” in any direction to facilitate the transfer of rotary motion. Ondrives.US’ unique telescoping U-joints provide zero backlash performance in any motion control application.

Zero Backlash in A Telescopic U-Joint

Our unique zero backlash telescopic universal joints feature precision balls, burnished custom spherical sockets, and accurately-sized components that help eliminate clearance between bearing surfaces under an elastic preload.

At full torque (up to 600 in-lbs.—varies by model), Ondrives.US telescoping shaft couplings provide zero backlash at operating angles up to 10°. At 50% torque, they operate with zero backlash at operating angles up to 30°.

Precision universal joints are available in a range of standard inch and metric bore sizes, from 3/16” to 1” and 5mm to 25mm. Any bore-to-bore combination is possible within those limits, making these zero backlash precision u-joints ideal for myriad applications.
