Twin-Rod Cylinder

FDF and FDXS Series

Twice the Thrust and Precise Positioning in a Space-Saving Footprint.

When your application demands high force output in a low-profile unit, the FDF and FDXS Series double-acting cylinders are an excellent choice. The cylinders’ twin rods deliver two times the thrust while the non-rotating design and standard magnetic piston ensure precise positioning. The cylinder features a tough, anodized aluminum housing and stainless piston rod. Additional features include rubber bumper cushions and nitrile Buna-N piston rod and piston seal.

The FDF Series comes with a sleeve bearing and is available in bore diameters from 10 to 25 millimeters, and the FDXS Series offers a precision recirculating ball bearing or sleeve bearing and diameters from 10 to 32 millimeters. Strokes range from 10 to 100 millimeters, and both series are interchangeable with other popular cylinders.
