About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X100-75S
A wide 75 mm trim window gives this 40 mm bore MAJ the most tuning latitude in its class: the external stop screw shortens the extend stroke anywhere inside the 100 mm base travel. Force stands at 628 N push and 528 N pull at 0.5 MPa, or 880 N push on a 0.7 MPa supply.
The riveted stainless round barrel resists rust in wet plants and stays compact, while the hard-chrome 16 mm rod shrugs off abrasion. Every unit carries a standard magnet for CMSG, DMSG or EMSG switches. In practice, plan on about 377 N of usable force at 0.5 MPa rather than the full 628 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 (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 MAJ40X100-75S Is Used
Case reject pusher on a carton line
About 377 N of working force knocks rejected cases off the belt, with the stroke trimmed to match the lane width.
Lid clamp on a mixing vat
The stainless body tolerates fumes above the vat while the rod pulls the lid down with about 528 N at 0.5 MPa.
Verified ejection on a pharma sorter
The built-in magnet and an EMSG switch confirm full extend before the sorter indexes the next tray of vials.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X100-75S the Right Cylinder?
Stepping down to a 32 mm bore costs you force - about 402 N push at 0.5 MPa versus 628 N here - so keep the 40 mm for heavier clamps; there is no larger MA bore, so the MACJ family is the next step up when cushions are needed. Remember the trim stop positions the rod but does not arrest it when air is lost; a mechanical clamp must hold the load. Mount via FA flange or LB foot, add an I or Y knuckle for pivoting tools, and keep this 100 mm stroke free of side load or guide it externally.
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 MAJ40X100-75S FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; raise the supply to 0.7 MPa for 879.6 N push and 738.9 N pull. At the 1.0 MPa theoretical limit the figure is 128.1 kgf. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
The stainless round barrel, hard-chrome plated 16 mm carbon-steel rod and riveted aluminium covers seal out splash and humidity. Air connects through 1/8" ports, the male rod thread is M12x1.25, and temperature spans -20 to +70 C.
