The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X350-10S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The MAJ32X350-10S pairs a 350 mm stroke with a 10 mm extend-trim window, so the outer limit of travel can be backed off on site using the external stop screw. It is double-acting throughout: at 0.5 MPa it pushes 402.2 N and pulls 345.6 N, rising to 563.0 N and 483.8 N at 0.7 MPa, with a theoretical 82 kgf ceiling at 1.0 MPa.
Work the numbers before ordering: 0.6 x 402.2 N leaves roughly 241 N for the actual job at 0.5 MPa, and halving the 41 kgf vertical-lift equivalent gives a comfortable 20 kg lift rating in practice. The stainless barrel plus hard-chrome rod combination is what separates this round-body mini from painted cylinders in food, outdoor or humid cells, and the fixed bumper pads - a deceleration aid, not an adjustable cushion - protect both ends of the long travel. The piston magnet comes as standard, so CMSG, DMSG or EMSG switches clip straight on.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
| Pressure | Push force | Pull force |

| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Slides a washdown gate between filler and labeler; the stainless barrel tolerates daily caustic rinse and the 10 mm trim lets the gate seating be nudged without re-plumbing.
Raises an 18 kg aluminium fixture plate on an assembly-cell riser - roughly 20 kg is the practical vertical rating with a 2:1 margin at 0.5 MPa.
Kicks off-spec cans over 350 mm of travel; 402.2 N of push at 0.5 MPa clears a full lane, and a CMSG switch confirms the home position.
If 402.2 N at 0.5 MPa is more than the job needs, the MA25 develops 245.3 N under the same pressure; when the load grows, the MA40 reaches 628.3 N. A 350 mm stroke puts real leverage on the 12 mm rod, so guide the load externally rather than letting the rod carry side force. FA flange and LB foot brackets, with I / Y knuckles as accessories, cover most mounting plans. And a sizing caution: the stop screw sets only where the extend stroke finishes - it is no substitute for a load-holding valve if the machine must stay put on air failure.
Quick checklist
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the figures are 563.0 N push and 483.8 N pull. The theoretical maximum at 1.0 MPa is 82 kgf. Supply runs 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, the air port is 1/8" and the male rod thread is M10x1.25.
An external stop screw limits the extend stroke to anywhere from 350 mm down to 340 mm - it shortens travel, never lengthens it past the ordered stroke. It acts only at the end of travel as a mechanical stop; it is not a mid-stroke brake, and the rod will still drift if air pressure is lost. Fixed bumper pads soften the touchdown.
