About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-40S
Few minis let you reclaim 40 mm of stroke after commissioning; this one does, via a stop screw outside the back cover that shortens the extend stroke across the whole 40 mm window. Output peaks at 628 N push at 0.5 MPa (880 N at 0.7 MPa) on a 0.15-1.0 MPa (22-145 psi) supply, so keep all-day loads nearer 377 N than the full rating.
The riveted round body pairs a stainless barrel with a 20 um hard-chrome carbon-steel rod, a real edge in humid or periodically hosed-down corners. Fixed bumper pads take the sting out of stroke ends at speeds up to 800 mm/s, and the built-in magnet works with CMSG / DMSG / EMSG switches straight from the box.

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 (Ø40mm)
| 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.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-40S Is Used
Gravity roller stop
Pops a stop blade up on a gravity spur to catch totes, with the 40 mm window tuning blade height to the load bed.
Guard gate closer
Swings an interlocked machine-guard gate shut and seats it squarely via the stop screw for reliable interlock alignment.
Fatigue test rig
Drives a 160 mm push-pull cycle on a component test rig at up to 800 mm/s, with magnet-based switches marking each reversal.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-40S the Right Cylinder?
Against bore 32 (402 N at 0.5 MPa) this size buys about 56 percent more push, and nothing in the MA range sits above it. A 160 mm stroke on a 16 mm rod wants external guiding for any side load. Choose FA flange or LB foot, add I or Y knuckles where the tool pivots, and spec G or NPT ports (1/8") if the standard PT thread does not match your plant. The adjuster gives a repeatable end stop but cannot arrest a suspended load when air pressure is lost.
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 MAJ40X160-40S FAQ
Expect 628 N forward and 528 N return at 0.5 MPa, rising to 880 N and 739 N at 0.7 MPa, with 128.1 kgf the theoretical peak at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air and cycle between 30 and 800 mm/s.
No. The MAJ carries fixed anti-impact bumper pads that merely soften deceleration at each end of travel. If your application needs tunable pneumatic cushioning on top of stroke adjustment, AirTAC's MACJ family adds that feature.
