About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-10S
Fine positioning is the whole point of the MAJ40X200-10S: the external stop screw narrows the 200 mm extend stroke to within a 10 mm window, so one catalog cylinder can be dialed onto a fixture's exact clamp or touch point. Double-acting throughout, it turns 0.15-1.0 MPa (22-145 psi) of air into 628.3 N of push at 0.5 MPa, with 527.8 N on the return. For continuous duty, budget around 377 N as the honest working force; halving the 64 kg static equivalent still gives you about 32 kg of vertical lift capacity.
Underneath is a riveted stainless round barrel with a hard-chrome plated 16 mm rod, so humid shops and rinse-down zones do not chew it up the way they do painted minis. The magnet ships standard for CMSG / DMSG / EMSG switches, and the fixed anti-impact bumper takes the sting out of each stroke end at speeds from 30-800 mm/s.

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 MAJ40X200-10S Is Used
CNC fixture clamping
Holds aluminium gear housings against a milling fixture; the 10 mm trim lets the clamp jaw land at the exact touch point, backed by 628 N at 0.5 MPa.
Part ejection from a bench die
Ejects small pressed spacers out of a stamping die on the upstroke; the short trim window keeps the kick length identical across changeovers.
Switch-checked assembly nest
A DMSG switch on the standard magnet confirms full clamp before the robot picks the part, cutting interlock wiring time on the cell.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X200-10S the Right Cylinder?
Lighter clamping jobs can drop to the MAJ25, which pushes 245 N at 0.5 MPa and sips less air; the 40 mm bore here is the ceiling of the MA range, so nothing in the family out-pushes it. FA flange and LB foot cover fixed mounting, while I or Y knuckles suit pivoting clamp jaws.
Note that the adjuster halts the rod at end of extend only - it is not a mid-stroke lock, and with air lost the piston will float under load. At 200 mm of stroke, keep the 16 mm rod side-load free by guiding the part itself.
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 MAJ40X200-10S FAQ
Push at 0.5 MPa is 628.3 N with 527.8 N on the return; raise the supply to 0.7 MPa and those become 879.6 N push and 738.9 N pull. Theoretical peak force at 1.0 MPa is 128.1 kgf. The rod is 16 mm with an M12x1.25 male thread, ports are 1/8", and it runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
No. A fixed anti-impact pad built into the covers decelerates the arrival; it softens impact only and is not an adjustable air cushion. Set speed with flow controls anywhere in the 30-800 mm/s band and let the pad absorb the residual shock. The magnet is fitted as standard, so CMSG, DMSG or EMSG switches drop on without special ordering.
