About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X90-40S
Machine builders who need a wider setting window get 40 mm of stroke trim here: the external stop screw shortens the 90 mm extend stroke anywhere inside that -40 range, so one cylinder can serve several fixture variants. Output stays at 402.2 N push and 345.6 N pull at 0.5 MPa (563.0 N push at 0.7 MPa), double-acting on a 0.15-1.0 MPa (22-145 psi) air supply.
The stainless round barrel and hard-chrome plated 12 mm rod keep corrosion at bay in humid or rinsed-down corners - a genuine advantage over painted aluminium minis. Stroke ends carry fixed anti-impact pads; for adjustable deceleration you would step to the MACJ series instead. The magnet is built in from the factory, so position sensing with CMSG, DMSG or EMSG switches needs no extra order. As a sizing anchor, design around 241 N of useful output at 0.5 MPa when you take 60 percent of the 402.2 N rating.

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 MAJ32X90-40S Is Used
PCB tray lane diverter for SMT lines
Routes electronics trays between two conveyor lanes, with the 40 mm trim absorbing fixture tolerances discovered during line commissioning.
Heat-seal head on a pouch machine
Presses seal jaws shut on small sachets, where 563 N at 0.7 MPa secures a crisp, repeatable seal at up to 800 mm/s cycling speed.
Harness test fixture clamp at a bench
Clamps wire-harness test fixtures closed during continuity checks; the wide 40 mm window covers several connector mould heights with one cylinder.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X90-40S the Right Cylinder?
A quick cross-check: 25 mm MAJ cylinders give 245.3 N push at 0.5 MPa and 40 mm units give 628.3 N - the 32 mm bore fits loads in between, such as 150-240 N clamps after derating. The stop screw is purely a mechanical end limit; if the machine must hold position against gravity with air off, fit a separate braking or counterbalance solution. Mount with the FA flange or LB foot, pair with I or Y knuckles as needed, and rely on the standard-fit magnet for CMSG / DMSG / EMSG sensing.
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 MAJ32X90-40S FAQ
Yes: 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and 82 kgf theoretical maximum at 1.0 MPa. Bore is 32 mm, rod 12 mm with M10x1.25 thread, port 1/8", working pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The barrel is stainless steel rolled directly onto the aluminium covers, and the 12 mm rod is hard-chrome plated to 20 um, so the cylinder tolerates washdown and humid air far better than painted bodies. Fixed bumper pads cushion the stroke ends, and the built-in magnet is ready for CMSG, DMSG or EMSG switches out of the box.
