Joints for Servo-Actuators


Used to eliminate misalignments and side loads from actuators and load cells, which could occurs during structure testing and damage or reduce the service life of your actuator or invalidate test results and cost you time.



Series JC

Series JC are designed for dynamic, alternating loading in connection with servo-actuators.

Backlash-free Cardan Joins

The rugged design provides backlash-free testing up to full force rating and longest service life. This series of joints are available up to high nominal force ratings and providing movements of ± 8°.

Series JB

Series JB Ball joints are used to protect actuators from unwanted side loads.

Backlash-free Ball Joints

Series JB are the ideal connection elements for dynamic testing in connection with servo hydraulic testing actuators. While oscillating loads are applied to the test object the ball joints allows rotating of the test object. The nominal angle of ball joints Series JB are ±20 degree in each axis. Nominal loads and connection flanges are adapted to the testing actuators up to 630 kN.

Series GK

They are available to fix on feet flange of the actuators or mountable on load cell on the end of the piston rod.

Swivel Bearings

Series GK consisting of rod eye with spherical plain bearing and clevis bracket. They are suitable for static or dynamic threshold testing. The through-zero clearance is approximate (depending on max. force rating) 0.05 to 0.15 mm. These joints represents a cost-effective solution to the backlash-free Series JC and JB.

Series GKD

The fatigue rated clevises have a clamp bolt to remove backlash and decrease noise when operated with reciprocation loads.

Fatigue Rated Swivel Rod Ends and Swivel Bases

The fatigue rated clevises have a clamp bolt to remove backlash and decrease noise when operated with reciprocation loads. Typical applications include fatigue testing of structures and components as well as vehicle durability testing. Swivel bases offer 360 degrees of rotation and ±30 degrees of angular displacement. Swivel: +30° to –90° / Tilt: ±7°.
