Techdrives precision universal joints transmit torque through high angles with consistent performance and long life. Single, double and telescopic models can run up to 45° with shafts from 6 to 50 mm and dimensions to DIN808. Construction is in steel with particular attention being paid to match the hardness of the wearing parts to achieve a long life. For more information see our frequently asked questions.
Universal joints are not flexible couplings. They transmit torque with angular misalignment but a single joint cannot accept parallel or axial misalignment. A single joint running at an angle will give an output where the speed fluctuates 4 times per revolution. To achieve smooth running, two single joints or a double joint is needed.
Types G,GD & GA universal joints have sliding plain bearings and suit operations up to 1000r/min. Gaiters are recommended to retain lubricant.
Types H,HD & HA are high speed universal joints with needle roller bearings suiting operation up to 4000 r/min.
Types GA and HA are telescopic universal joints designed to connect machine parts where axial movement is made without torque loading. When torque is transmitted they have a tendency to axially lock. A standard range is available on short lead times, alternatively special lengths can be constructed.
Universal joints are often fixed to the shafts by cross-
For severe environments universal joints of sizes 01-
Special bores such as splined and square, also quick release hubs can be considered on request.
Universal joint selection is based on speed, leading to a choice between plain and needle roller bearings, the working angle and the torque to be transmitted. See our FAQ Frequently Asked Questions guide for more details.
