About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X95-30S
A stainless round barrel with a rolled, riveted body puts the AirTAC MAJ40X95-30S among the toughest 40 mm minis for damp or washdown locations, an edge over painted-steel micro cylinders in food and outdoor spots. This double-acting piston delivers 628 N pushing at 0.5 MPa and 528 N on retract, and an external stop screw lets you trim the 95 mm extend stroke by up to 30 mm on site without touching the air supply.
For real work, budget around 377 N at 0.5 MPa instead of the full 628 N rating - that holds a 2:1 force margin on clamps and lifts, and the same math says the 16 mm hard-chrome rod raises about 32 kg vertically with margin. Fixed anti-impact pads ease the ends of travel (they decelerate only; air cushioning is the MAC family's job), and the built-in magnet picks up CMSG, DMSG or EMSG switches with no special-order piston.

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 MAJ40X95-30S Is Used
Lift-assist pick head
A robotic pick head on a packaging line raises trays of about 30 kg vertically; the halved lift figure of roughly 32 kg keeps a margin, and the 30 mm trim dials in the exact release height.
Reject gate with feedback
On a bottling conveyor, CMSG switches clamped to the standard magnet confirm gate open and closed, while the stop screw sets a repeatable throw of anywhere from 65 to 95 mm.
Washdown press fixture
The stainless barrel and chrome-plated rod shrug off daily hose-down in a food plant; 628 N at 0.5 MPa seats lids, and the bumper pad softens the seat before end of stroke.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X95-30S the Right Cylinder?
Bore 40 tops the MA range: it pushes 628 N at 0.5 MPa where a 32 mm bore manages 402 N, so step down to 32 mm if your load stays under about 240 N of work. If you need more than this class offers, no larger MA bore exists - move up a series. Note that the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: if air pressure drops, the rod still drifts, so add a separate holding valve for suspended loads. Mounting covers FA flange and LB foot, plus I and Y rod knuckles, and the magnet ships standard in every unit. At 95 mm of travel, keep side loads off the rod or guide them externally to protect the barrel and seals.
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 MAJ40X95-30S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa that rises to 879.6 N push and 738.9 N pull. The theoretical maximum for the 40 mm bore is 128.1 kgf at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi) and piston speed 30-800 mm/s.
No. Every MAJ ships with the magnet built in as standard, so CMSG, DMSG and EMSG sensors clamp straight onto the 40 mm stainless barrel and read end of stroke or any stop-screw setpoint you dial in, at no extra option cost.
