About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X75-10S
The MAJ40X75-10S pairs the largest bore in AirTAC's MA mini line with a 10 mm on-site trimming window, so a 75 mm extend stroke can be shortened anywhere within the first 10 mm without swapping the cylinder. At 0.5 MPa it delivers 628.3 N in push and 527.8 N in return, which in day-to-day sizing means roughly 377 N of usable work once the usual 60 percent margin is kept. The double-acting piston runs on filtered air at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
The body is a riveted stainless-steel round barrel with a hard-chrome plated carbon-steel rod, a combination that shrugs off mild corrosion and splash in damp or washdown-prone corners where painted minis give up. A magnet is built into the piston as standard, so CMSG, DMSG and EMSG reed switches snap straight on for end-of-stroke signalling 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 MAJ40X75-10S Is Used
Tray filling head
A 75 mm tap-down head on a packaging tray filler can be trimmed to 65-75 mm as tray depths change, with 628.3 N at 0.5 MPa seating product without bottoming out.
Washdown fixture clamp
The stainless barrel and chrome rod let this cylinder clamp food-line fixtures that get rinsed daily, holding parts against a 377 N working push at 0.5 MPa.
Reject station with position check
DMSG switches read rod position at both ends of the trimmed stroke, letting a bottle reject gate confirm it fully retracted before the next bottle passes.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X75-10S the Right Cylinder?
Stepping down to the 32 mm bore saves space but drops push force to 402.2 N at 0.5 MPa, so the 40 mm MAJ40X75-10S is the pick when a 75 mm stroke must still carry real load. Since 40 mm is the top of the range, run two cylinders in parallel if 628.3 N is not enough. Bear in mind the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: if air is lost the piston can still move. FA flange and LB foot mounts, plus I and Y rod knuckles, cover most fixings, and the standard magnet accepts CMSG or DMSG switches.
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 MAJ40X75-10S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa push rises to 879.6 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -10 window lets an external stop screw trim the 75 mm extend stroke by up to 10 mm on site. The return stroke stays fixed, the bumper pads are non-adjustable, and the unit is double-acting on air at 0.15-1.0 MPa (22-145 psi).
The barrel is stainless steel rolled onto aluminium covers in a compact riveted package, and the carbon-steel rod carries 20 um of hard chrome. Unlike painted minis, this finish tolerates splashes, humidity and mild washdown. Note that the fixed bumper pads only soften the strike at each end of travel; they are not adjustable cushions, which belong to AirTAC's MACJ range.
