The AirTAC AirTAC TR25X20S Twin-Rod Cylinder, Bore 25mm, 20mm Stroke is a genuine TR twin-rod (double-rod) double-acting cylinder, 25 mm bore. Two parallel rods on one plate resist bending and twisting and let the load mount without rotating. It delivers about 490.9 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.
A twin-rod cylinder runs two parallel rods on a shared plate so the load resists bending and twisting without rotating. The AirTAC TR25X20S pairs a 25 mm bore with a 20 mm stroke, producing a theoretical push thrust of 490.9 N at 0.5 MPa. The external bumper both cushions end-of-stroke impact and adjusts the stroke over a -5 to 0 mm range.
This is a genuine AirTAC part to JIS standard. The TR line features a lengthening sliding-support guide that raises non-rotating precision and lowers rod-end deflection, and it needs no added lubricant. Two groups of ports sit on both sides. A magnet is standard, with 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.
Pick the 25 mm bore for 490.9 N push thrust at 0.5 MPa (pull thrust is lower). TR follows JIS standard with a precise sliding guide and two port groups on both sides; TN follows enterprise standard and is PT-thread only. On TR, choose PT (standard on this model), G, or NPT thread. Keep the stroke within the bore's table; avoid over-long strokes with the short cover. We confirm side-load limits from the published curves on request.
Push a part sideways from one station to the next on a line. The 20 mm stroke gives enough travel to clear a fixture, and the twin rods keep the pusher face aligned without rotation.
Lift a lightweight pallet or tray a short distance to align it for the next operation. The 25 mm bore provides 490.9 N at 0.5 MPa, and the twin-guide design holds the lift plate level.
Move a diverter gate to route product between two conveyor lanes. The non-rotating twin rods keep the gate blade straight, and the bumper softens each end-of-stroke stop.
TR cylinders offer PT, G, and NPT thread. This TR25X20S has no trailing thread letter, so it ships with PT thread. TN cylinders are PT-thread only.
The TR uses a lengthening sliding-support guide for higher non-rotating precision and lower rod-end deflection, with no added lubricant needed. Allowable side-load and deflection are published as curves; we confirm the values for your case from the datasheet.
