About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-10S
Fine end-position tuning is the point of the MAJ40X175-10S: a 10 mm extend-stroke window on a 40 mm bore, 175 mm stroke, double-acting mini cylinder. The external stop screw lets technicians shave up to 10 mm off the extend stroke after installation - useful for seating, docking or gauging where the final millimetres matter. Force at 0.5 MPa: 628 N push, 528 N pull, working pressure 0.15-1.0 MPa (22-145 psi).
The riveted stainless round body and 20 um hard-chrome rod stand up to humidity and light washdown, an advantage over painted or bare-aluminium minis. A fixed bumper pad softens the impact at the trimmed end, and the standard-fit magnet accepts CMSG / DMSG / EMSG switches without ordering a special piston. Keep continuous loads near 377 N, or about 32 kg of vertical lift with a 2:1 margin; speed range 30-800 mm/s on 40 um filtered air.

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 MAJ40X175-10S Is Used
Precision docking of test probes
Electronics test rigs use the 10 mm window to set exact probe seat depth; the DMSG switch confirms the trimmed endpoint each cycle.
Bench-top press for connector crimps
628 N at 0.5 MPa crimps small terminals, and the hard-chrome rod resists metal dust in the workshop environment.
Gauge stops on metrology fixtures
Shave the extend stroke until the gauge face sits flush; 880 N at 0.7 MPa holds workpieces steady during measurement.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-10S the Right Cylinder?
Against the range: the 32 mm bore pushes 402 N at 0.5 MPa, while this 40 mm bore - the largest in the MAJ line - pushes 628 N, so pick the smaller size when 240 N of working force is plenty. The 10 mm window is best when the stroke itself is fixed and only the seating depth needs adjustment; wider windows (50-100 mm) exist for looser tolerances. The adjuster is a mechanical stop for the extend direction only: it holds nothing on air loss and cannot lengthen travel past 175 mm. FA or LB mounting, I or Y knuckles; with a 16 mm rod over 175 mm, keep the load guided against side thrust.
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 MAJ40X175-10S FAQ
Double-acting with a 10 mm extend-stroke adjuster. Forces: 628.3 N push / 527.8 N pull at 0.5 MPa, 879.6 N / 738.9 N at 0.7 MPa, 128.1 kgf theoretical peak at 1.0 MPa. Port 1/8", rod thread M12x1.25, rod 16 mm, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
The MAJ's stainless barrel with a hard-chrome plated rod resists mild corrosion, splashes and light washdown far better than painted-steel or bare-aluminium minicylinders, while covers rolled onto the tube give a compact, sealed round profile.
