About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X125-50S
A double-acting mini cylinder with an adjustable extend stroke: an external stop screw trims the extend stroke on site anywhere inside the ordered 50 mm window, so one body covers several fixture positions. The round stainless barrel with its hard-chrome 12 mm rod resists mild corrosion and washdown far better than painted mini bodies in damp or food-area duty.
At 0.5 MPa the 32 mm bore delivers about 402 N pushing and 346 N pulling; run it at 0.7 MPa and push rises to 563 N, with a theoretical ceiling of 82 kgf at 1.0 MPa. Plan on roughly 241 N of usable work at 0.5 MPa, about 60 percent of the rating, so actuators are never sized on the edge. Fixed bumper pads soften stroke-end impact, they decelerate only and adjustable cushioning lives in the MAC family, and the built-in magnet is standard, so CMSG, DMSG or EMSG switches mount 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.
Theoretical Output Force (Ø32mm)
| 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.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X125-50S Is Used
Capper head press
Presses caps onto cosmetic bottles on a 125 mm travel packing station, with the 50 mm trim window letting one cylinder serve tall and short containers.
Die ejector
Kicks small stamped parts clear of a punch die, using 402 N at 0.5 MPa for light aluminium blanks.
Glue head set-down
Sets a hot-glue nozzle to part height on a carton line; the stop screw is retuned in seconds during changeover.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X125-50S the Right Cylinder?
For lighter duty the 25 mm bore gives 245 N push and 206 N pull at 0.5 MPa; for more, step to the 40 mm bore at 628 N and 528 N. The stop screw sets extend position only - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost and it must never be read as a load-holding brake. Mount with an FA flange or LB foot, add I or Y rod knuckles, and rely on the standard magnet for switching. At 125 mm of stroke, guide any side load externally to keep the 12 mm rod out of bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X125-50S FAQ
Push at 0.5 MPa is 402 N and pull is 346 N; at 0.7 MPa push reaches 563 N and pull 484 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The bore is 32 mm with a 12 mm rod and 1/8" ports, stroke 125 mm with a 50 mm adjustable extend window, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), and -20 to +70 C operation.
An external stop screw shortens the extend stroke anywhere within the ordered 50 mm window; it cannot push travel past the ordered 125 mm stroke. Fixed bumper pads soften end impact but are not adjustable air cushions. Every MAJ ships with a built-in magnet, so CMSG, DMSG and EMSG switches clip on without a special piston - no extra-order option needed.
