Specifications
The PO-A Dual-Guide Anti-Rotation and Oscillating Rigid Protection is the combination of our PO Oscillating Rigid Protection and the Dual-Guide Anti-Rotation system and it is used in those oscillating, piston-rod applications where the user needs to contrast the inherent tendency to rotate that every screw jack presents. The PO-A Dual-Guide Anti-Rotation and Oscillating Rigid Protection, applicable on the KT Series, is a special Oscillating Rigid Protection (PO) with an eyelet in the lower extremity and two embedded linear guides with a no-friction Keniflon-treated bushing connected to the trapezoidal screw. In cases of longer strokes it is necessary to verify that torsional forces may not pose the risk of damaging the bushing. Because the anti-rotation system locks the screw and the end-fitting in a specific position, it is always necessary to specify the exact position of special holes or asymmetrical/non-centered details in the ball screw. Please keep in mind that the use of the PO-A and a rod-end, does not eliminate lateral loads. When working with compression loads, it is necessary to verify the load capacity under he 2nd Euler’s Law: when using the formualae please consider the center-to-center distance between the eyelet and the rod-end. A motor can be installed directly on the screw jack.
