About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X150-40S
Double-acting air power in a corrosion-resistant round body: the MAJ32X150-40S pairs a stainless-steel tube with a hard-chrome plated 12 mm rod, and its -40 suffix lets the external stop screw pull the extend stroke back anywhere inside a 40 mm band. Force at 0.5 MPa is 402.2 N push and 345.6 N pull - the middle ground between the 25 mm bore (245.3 N) and the 40 mm bore (628.3 N).
On vertical lifts the raw 402.2 N equals about 41 kg, so with a 2:1 safety margin it raises roughly 20 kg. The magnet is standard fitment, feeding CMSG/DMSG/EMSG switches without a special piston, and 1/8" ports keep the plumbing compact on small machines.

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 MAJ32X150-40S Is Used
Reject pusher on a food-grade conveyor
The riveted stainless body survives washdown that swells painted minis, while 402.2 N at 0.5 MPa clears off-spec packs cleanly.
Reagent tray indexing in a lab autosampler
A 40 mm trim window lets the extend stop track tray pitch changes, and CMSG switches confirm each position since the magnet is built in.
Lid clamp for small paint-mix vessels
With a 2:1 margin the rod lifts about 20 kg vertically - enough to hold light lids closed during mixing at 0.5 MPa.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X150-40S the Right Cylinder?
Compare against neighbours before ordering: 25 mm bore gives 245.3 N at 0.5 MPa and 40 mm bore gives 628.3 N - if your load needs more than about 241 N of working force, stay with this 32 mm size. At 150 mm of extension keep side loads off the 12 mm rod and guide the load externally on long pushes. FA flange and LB foot cover fixed mounting, while the standard magnet pairs with CMSG/DMSG/EMSG switches for stroke-end detection.
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 MAJ32X150-40S FAQ
Expect 402.2 N forward and 345.6 N on the return at 0.5 MPa, rising to 563.0 N and 483.8 N at 0.7 MPa; theoretical peak is 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, with a 1.5 MPa (215 psi) proof rating and speeds of 30-800 mm/s.
No - every MA-series cylinder ships with a built-in magnet, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel without a special-order piston. The -40 suffix defines the 40 mm band in which the stop screw can trim the extend stroke on site.
