About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X350-100S
Need 350 mm of stroke but not always all of it? The -100 window on this MAJ40X350 lets the stop screw take back up to 100 mm of extend travel at the machine, so one cylinder fits a family of frames. Bore 40 gives 628.3 N push at 0.5 MPa and 879.6 N at 0.7 MPa, a heavy-lifting class for a mini round body.
Two details pay off on the floor: the magnet comes standard for CMSG / DMSG / EMSG position feedback, and the heterogeneous piston seal stores grease in its groove to stretch service intervals. Convert 628.3 N to practical terms and you get about 377 N of working force, or roughly 32 kg lifted vertically with a 2:1 margin.

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 MAJ40X350-100S Is Used
Stop gate on a parcel sortation roller bed
350 mm of reach deploys across a roller lane; the 100 mm trim adapts the gate depth per chute, backed by 628.3 N at 0.5 MPa.
Tray denester pusher in a food plant
The stainless barrel and chrome rod stand up to daily hose-down; a practical push of about 377 N separates and feeds tray stacks cleanly.
Grain hopper slide gate
The grease-retaining two-way seal keeps the piston moving through dusty seasons, and 879.6 N at 0.7 MPa shifts a stalled gate open.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X350-100S the Right Cylinder?
Bore 32 delivers 402.2 N at 0.5 MPa - choose it when 628.3 N is overkill; above bore 40 the MA series ends, so look at larger Airtac families for more force. Because the adjuster is an extend-side mechanical stop rather than a lock, a dropped air supply still lets the rod move under load - fit a pilot-checked or locking valve where holding matters.
FA flange or LB foot, plus I / Y knuckles, cover the mounting. A 350 mm stroke with a 16 mm rod is side-load sensitive: support long workpieces on their own guide. Air ports are 1/8" and the male rod thread is M12x1.25.
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 MAJ40X350-100S 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; 128.1 kgf theoretical maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, with a 100 mm adjustable extend window.
The barrel is stainless steel and the carbon-steel rod carries a 20 um hard-chrome plate, a pairing that resists rust from condensation and washdown where painted or plain aluminium minis pit. The aluminium-alloy covers are riveted and rolled onto the tube for a sealed, reliable joint.
