The AirTAC TR20X20S AirTAC Dual-Rod Cylinder, 20mm Bore, 20mm Stroke 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 TR20X20S is a double-acting twin-rod cylinder: two parallel rods on one shared plate carry the load, so the plate moves without rotating and resists bending and twisting. The 20 mm bore delivers a theoretical push thrust of 314.2 N at 0.5 MPa (pull side slightly lower), and the short 20 mm stroke suits compact eject, clamp and stopper positions where space is tight. An external front bumper cushions end-of-stroke impact and adjusts the effective stroke over -5 to 0 mm.
This is a genuine AirTAC part built to the JIS-standard TR series, the precise guide grade with high non-rotating accuracy, low rod-end deflection and a lengthening sliding-support guide that needs no added lubricant. The position-sensing magnet is fitted as standard, with magnetic-switch slots around the body. We confirm dimensions and sizing 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.
Match the bore to the thrust: this 20 mm bore gives up to 314.2 N of theoretical push force at 0.5 MPa, so use it where a 10 or 16 mm bore would fall short of the force you need. Between the two AirTAC twin-rod ranges, TN is the enterprise-standard line (PT thread only), while this TR is the JIS-standard, precise guide grade - choose it when non-rotating accuracy and low rod-end deflection matter. The 20 mm stroke is at the short end of the bore-20 table, ideal for tight envelopes; for long travels, check that short covers are not required. Route side-load and deflection limits to us - they are published as curves. Thread options on TR are PT, G or NPT; this model is PT.
The non-rotating plate ejects a finished part from a machining fixture in a compact 20 mm move, staying square to the part without extra guiding.
A short 20 mm clamp move holds a workpiece against a jig stop; the twin rods stop the pad twisting as pressure builds.
The plate rises 20 mm into the path of a pallet to index flow; the bumper cushions each arrival and trims the exact stop height.
At 0.5 MPa the push side of the TR20X20S delivers a theoretical thrust of 314.2 N; the pull side is slightly lower because the rods reduce the effective area. Operating pressure for this bore is 0.15-1.0 MPa (22-145 psi), with air filtered to 40 um.
It is an external pad, not an air cushion: it cushions the impact at end of stroke and also adjusts the effective stroke over -5 to 0 mm, so you can trim the final plate position. Exact dimensional fit for your fixture is confirmed from the datasheet.
