AirTAC TR Series Twin-Rod Cylinders

The TR series is a double-acting pneumatic cylinder with two parallel piston rods driving one shared front plate. Because the two rods work together, the cylinder delivers double the output force for its bore, resists bending and twisting, and can carry a certain lateral load - so the load does not deflect or spin the way it would on a single-rod cylinder. Bores run from 6 mm (a size only TR offers in this family) up through 10, 16, 20, 25 and 32 mm, with standard strokes from 10 mm up to 50 mm on bore 6, 100 mm on bore 10 and 200 mm on bores 16-32. The 6 mm bore needs 0.2-1.0 MPa (29-145 psi) to start; bores 16-32 run from 0.15-1.0 MPa (22-145 psi). Speed range is 30-500 mm/s, temperature -20 to +70 C, and the medium is air filtered to 40 um or finer.

TR is built to the JIS standard, which is the key difference from its sibling TN, built to AirTAC's own enterprise standard. TR also carries an extended sliding-bearing guide that gives high non-rotation accuracy and small rod-end deflection at the rod end, so it suits precise guiding duty - and that guide needs no added oil lubrication. An anti-collision pad at the front of the body cushions the impact and lets you shorten the effective stroke by setting the pad. Every model is magnet-fitted as standard, and a sensor drops into a groove that runs around the body - no band or bracket needed.

Practical build detail: the fixed plate has mounting holes on three faces (top, front, bottom), the body has mounting holes on every face except the axial ends, and there are two sets of inlet/exhaust ports, one on each side, so you can pipe from whichever side suits the run. Ports are M5x0.8 on bores 6-20 and 1/8 PT / G / NPT on bores 25 and 32. Ordering code: TR{bore}x{stroke}S{thread}, e.g. TR20x50S or TR32x100SG.
