About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-100S
At the top of the MAJ force range, the MAJ40X200-100S pairs a 40 mm bore with a 200 mm stroke whose extend side can be trimmed by up to 100 mm using the external stop screw. It is double-acting, runs on 0.15-1.0 MPa (22-145 psi) of 40 um filtered air at 30-800 mm/s, and delivers 628 N pushing at 0.5 MPa (880 N at 0.7 MPa). Plan real work near 377 N, about six tenths of the push rating, and you have roughly 32 kg of vertical lifting capacity at a 2:1 margin.
The stainless round barrel with its 20 um hard-chrome plated rod shrugs off the moisture that swells painted-steel minis, a genuine edge in washdown corners and outdoor gates. The riveted round body keeps the footprint tight, a magnet is fitted as standard so CMSG, DMSG or EMSG switches clip straight on, and the fixed anti-impact pad softens stroke-end shock without any cushion valve to tune.

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 MAJ40X200-100S Is Used
Capping press head
Seats caps on 500 ml bottles in a beverage plant; the 100 mm trim window lets one cylinder serve both tall and short bottle formats with 628 N at 0.5 MPa behind the seating stroke.
Reject gate on a checkweigher
Kicks overweight packs off the conveyor between weigh cells; the built-in magnet and a CMSG switch confirm gate-open status straight to the PLC.
Bench press for bushing insertion
Presses bronze bushings into pump housings at a maintenance bench; the roughly 377 N working band suits interference fits in aluminium bodies.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-100S the Right Cylinder?
If 628 N at 0.5 MPa leaves too much headroom, step down to the MAJ32, which pushes 402 N under the same pressure; 40 mm is the widest bore the MA series offers, so heavier jobs need a larger-bore family. Pick FA flange or LB foot for the frame and add I or Y rod knuckles where the tooling should pivot.
Two cautions at 200 mm of travel: guide the load externally so side loads stay off the 16 mm rod, and remember the stop screw only sets the end of extend - it is not a brake, and a de-pressurized rod can still drift under load.
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 MAJ40X200-100S 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 and pull to 738.9 N. Theoretical maximum force at 1.0 MPa is 128.1 kgf. Working pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the speed range is 30-800 mm/s.
It is a riveted round-body cylinder: a stainless-steel barrel with rolled aluminium-alloy covers, a stainless block, and a 16 mm hard-chrome carbon-steel rod with M12x1.25 male thread. Air ports are 1/8". The standard built-in magnet lets CMSG, DMSG and EMSG switches mount on the barrel with no special-order piston.
