About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X150-75S
A 75 mm on-site trim range makes the MAJ40X150-75S the flexible choice when stroke lengths are still being settled. Double-acting throughout, it pushes 628.3 N and pulls 527.8 N at 0.5 MPa - 879.6 N and 738.9 N at 0.7 MPa, peaking at 128.1 kgf - and the external stop screw cuts the 150 mm extend travel down to 75 mm. It operates on 0.15-1.0 MPa (22-145 psi).
Because the barrel is stainless steel and the 16 mm rod is hard-chrome plated, this round-body cylinder handles daily washdown and outdoor exposure that ruin painted mini cylinders. Derate to about 377 N of continuous working force at 0.5 MPa for real payload, and note the magnet is already built in, so CMSG, DMSG and EMSG switches mount straight onto the body.

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 MAJ40X150-75S Is Used
Dairy Filler Reject
Kicks a tipped bottle off a dairy filler conveyor; the stainless barrel and chrome rod shrug off the daily caustic washdown that swells painted minis.
Outdoor Gate Actuator
Opens a small sluice gate on an outdoor rinse skid, where corrosion resistance rather than raw force decides cylinder life.
Tray Clamp
Clamps filled trays onto a checkweigher belt using roughly 377 N of real working force at 0.5 MPa, well inside the cylinder rating.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X150-75S the Right Cylinder?
Size down to the MAJ32X150-75S, which still manages 402.2 N of push at 0.5 MPa, if your load stays light; the MA range tops out at this 40 mm bore. Mount via FA flange or LB foot, with I and Y rod knuckles available - adjustable models ship without the SDB option. The adjuster is an extend-side stop only; it never locks the piston mid-stroke or against air loss, so add a separate hold for critical loads. With 150 mm of travel on a 16 mm rod, keep side loads on external guides.
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 MAJ40X150-75S FAQ
Push at 0.5 MPa is 628.3 N and pull 527.8 N; at 0.7 MPa the pair becomes 879.6 N and 738.9 N; the theoretical maximum is 128.1 kgf. The extend stroke of 150 mm can be trimmed by up to 75 mm with the stop screw, giving a shortest extend of 75 mm.
Yes - the round barrel is stainless steel and the piston rod is carbon steel hard-chrome plated to 20 um, while the aluminium covers are rolled and riveted onto the tube for a sealed joint. Keep supply air filtered to 40 um and within 0.15-1.0 MPa (22-145 psi) and -20 to +70 C.
