The AirTAC Airtac TR Twin-Rod Cylinders TR20X75S is a genuine TR twin-rod (double-rod) double-acting cylinder, 20 mm bore. Two parallel rods on one plate resist bending and twisting and let the load mount without rotating. It delivers about 314.2 N of push at 0.5 MPa. A front bumper cushions the impact and adjusts the stroke over a -5 to 0 mm range. As the JIS guide-grade series it adds high non-rotating precision, a lengthening sliding guide (no added lubricant) and two-side ports.
The TR20X75S is a double-acting twin-rod cylinder whose two parallel rods carry a single mounting plate that moves without rotating, so a load bolted to the plate is guided against bending and twisting through the full 75 mm travel. The 20 mm bore gives a theoretical push thrust of 314.2 N at 0.5 MPa on the push side (pull side is lower). An external bumper cushions end-of-stroke impact and allows stroke adjustment over -5 to 0 mm.
This is a genuine AirTAC part in the JIS-standard TR series, the guide-grade twin-rod line offering high non-rotating accuracy, low rod-end deflection and a lengthening sliding-support guide requiring no added lubricant. The magnet is standard equipment, with magnetic-switch slots around the body. Exact dimensions for this stroke are confirmed from the datasheet on request.

Specifications follow the official AirTAC TN/TR twin-rod data. Operating pressure is set by bore (0.2 MPa minimum on the 6 and 10 mm bores). The front cover and piston are short, so avoid an over-long stroke. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
The 20 mm bore delivers 314.2 N theoretical push at 0.5 MPa; size up to 25 or 32 mm if your job needs more force. TR is the JIS-standard precision-guide series; TN is the enterprise-standard alternative with PT thread only, whereas TR lets you specify PT, G or NPT - this model comes with PT ports. 75 mm is one of the longer listed strokes for the 20 mm bore, so check the short-cover caution before selecting an over-long stroke, and route side-load and mounting questions to us for confirmation against the datasheet.
Fitted beside a conveyor, the plate pushes totes or small pallets onto a spur line; the long 75 mm travel clears the lane and the plate stays square under load.
The non-rotating plate squares up parts or trays before a pick or pack step, guiding them straight through the stroke without twisting off-line.
In analyser and sample-handling modules, the twin-rod plate moves trays or slides precisely between positions, where straight, repeatable travel matters more than raw force.
S indicates the magnet, which is fitted as standard across the whole TR series - there is no non-magnetic option. The code also gives a 20 mm bore, 75 mm stroke and PT thread. As a 20 mm bore model it operates at 0.15-1.0 MPa (22-145 psi), with proof pressure of 1.5 MPa (215 psi) and an air medium filtered to 40 um.
75 mm is a listed stroke for the 20 mm bore, but longer strokes on twin-rod cylinders deserve a check: the catalogue carries a short-cover caution against over-long strokes, and allowable side load is given as curves rather than a single figure. Confirm your stroke and load case from the datasheet or ask us before finalising the choice.
