The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X225-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 225mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
The MACJ40X225-10S pairs a 40 mm bore with a 225 mm stroke and a 10 mm on-site trim window, so the extend stroke can be shortened by up to 10 mm without swapping cylinders. It is double-acting with a variable air cushion at both ends, runs on filtered air at 0.15-1.0 MPa (22-145 psi) and travels at 30-800 mm/s. At 0.5 MPa it pushes with 628 N and pulls with 528 N, rising to 880 N of push at 0.7 MPa.
The round stainless barrel and hard-chrome plated 20 um rod shrug off mild corrosion, washdown splashes and outdoor damp far better than painted steel minis. Every unit ships with a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip straight on. For sizing, plan on roughly 377 N of usable push at 0.5 MPa rather than the full 628 N rating, and remember the trim screw is a mechanical end stop, not a mid-stroke lock: if air is lost the rod can still drift.

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 | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

|---|---|
| 40 | Bore size in mm. |
| ×225 | Stroke length in mm. |
| -10 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
Lifts and drops machined housings between pallets; the 628 N push at 0.5 MPa comfortably handles a 32 kg vertical payload with margin, and the 10 mm trim lets you zero in on the drop height.
Nudges bottles onto a side rail on a rinse-down line, where the stainless barrel and chrome rod outlast painted minis; the both-end cushion stops glass-on-glass clatter at speed.
Tucks top flaps before taping; the adjustable window absorbs small carton-height variation, and the standard magnet feeds end-of-stroke signals to the taping PLC.
Compared with the 32 mm bore (402 N push at 0.5 MPa) this cylinder gives well over half again the force, and if you need more still the 50 mm bore delivers 981 N. The 10 mm window suits fine trim near the final position; order the -20 or -40 variant when the extend stroke needs a wider tuning range. Mount with the FA flange or LB foot, add I or Y rod knuckles where the load pivots, and keep side loads off the 16 mm rod at full 225 mm extension.
Quick checklist
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those become 879.6 N push and 738.9 N pull, with a theoretical peak of 128.1 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, temperature -20 to +70 C, and the extend stroke trims within the 10 mm window. The 16 mm rod thread is M12x1.25 and the port is 1/8".
Yes, every MA-series cylinder carries a built-in magnet at no extra charge, so AirTAC CMSG, DMSG and EMSG reed or Hall-effect switches mount directly on the stainless barrel for end-of-stroke signalling. No special-order piston or bracket fabrication is needed, and switches can be repositioned anywhere along the tube as the cycle changes.
