About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X225-100S
The widest trim window in this bore class belongs to the MAJ40X225-100S: up to 100 mm of the extend stroke can be shortened at the machine through its external stop screw. The 40 mm bore delivers 628.3 N of push at 0.5 MPa, supplied with 0.15-1.0 MPa (22-145 psi) air filtered to 40 um.
Halve the 64 kg full-rating vertical lift and you get about 32 kg as a sensible lifted load per cylinder. Double-acting air drives the rod both ways, fixed anti-impact pads ease the ends of travel without being adjustable cushions, and the standard-built magnet works with CMSG, DMSG and EMSG switches from day one.

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 MAJ40X225-100S Is Used
Tote-transfer lift
Lifting totes between two roller levels in a small distribution centre, the cylinder raises about 30 kg totes with margin to spare on the 64 kg rating.
Film-carriage sizing
On a stretch-wrapping turntable retrofit, technicians reset the stop screw so carriage travel matches different pallet heights without swapping cylinders.
Press-fit anvil
Seating bearings into housing bores on a maintenance bench uses the roughly 880 N push available at 0.7 MPa, with anvil height set inside the 100 mm window.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X225-100S the Right Cylinder?
Against its neighbours: the 32 mm MA reaches only 402 N at 0.5 MPa, while this 40 mm bore tops the range at 628.3 N push and 527.8 N pull. Keep working loads near 377 N or less and the cylinder lives longer.
Because the -100 adjuster is a mechanical stop, not a mid-stroke brake, a suspended load will still settle if air pressure drops - fit a blocking valve where that matters. The 225 mm stroke sits well inside the 500 mm standard ceiling for bore 40, but at this length guide side loads externally to protect the hard-chrome rod. FA flange, LB foot, plus I or Y knuckles cover most fixings, and the built-in magnet keeps sensor retrofits simple.
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 MAJ40X225-100S 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 peak 128.1 kgf at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, extend stroke trimmable by up to 100 mm.
No. The MAJ carries fixed anti-impact pads that merely soften the piston's arrival at each end - they cannot be tuned like an adjustable cushion, which is the MAC family's trick. If a job needs metered deceleration over this stroke, step up to the MACJ series; if the load must be gripped on both sides of the piston, look at the MAD double-rod version.
