Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 

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.
