About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-30S
Air feeds both sides of the piston on the MAJ40X175-30S, and an external stop screw trims the extend stroke up to 30 mm short of the 175 mm build, ideal once the machine frame is bolted down and the exact rest position is known. At the 40 mm bore the rod carries 628 N out and 528 N back at 0.5 MPa. Running range is 0.15-1.0 MPa (22-145 psi) with rod speeds of 30-800 mm/s.
A riveted stainless barrel plus a hard-chrome carbon rod give this mini real stamina in humid workshops; there is no tie-rod kit to creep and no paint to flake. Set realistic duty near 377 N at 0.5 MPa, about 60 percent of rated push, and the cylinder stays comfortably inside its envelope through millions of cycles.

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 MAJ40X175-30S Is Used
Bottling line diverter
Kicking bottles or jars onto a reject lane: 628 N at 0.5 MPa is ample, and the 30 mm window tunes where the diverter parks.
Fixture clamp on a drill jig
Clamping steel plates in a drilling fixture where the 175 mm approach clears the swarf guard and the stop screw pins the clamp jaw precisely.
Lid press-down station
Pressing snap-on lids onto tubs, with the extend stop shortened 30 mm so the press lands on the rim rather than over-travelling.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-30S the Right Cylinder?
For comparison, the 32 mm bore delivers 402 N at 0.5 MPa against 628 N here, so pick the 32 only if duty stays under roughly 240 N. Remember the stop screw sets an extend end point, not a holding lock; with air gone, the piston is free to move. Mount FA flange or LB foot, or fit I and Y knuckles on the rod. The magnet is factory-standard, so CMSG / DMSG / EMSG reed switches bolt on with no special piston order.
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 MAJ40X175-30S FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. Port size is 1/8" on every 40 mm MA body, rod thread M12x1.25.
No. Every MAJ ships with the piston magnet already fitted as standard, so CMSG, DMSG or EMSG switch models from AirTAC click onto the barrel for end-of-stroke or position signalling.
