About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-100S
The widest trim window in the MAJ line, 100 mm, belongs to the MAJ40X160-100S: the external stop screw cuts the 160 mm extend stroke down to 60 mm on site. Output is 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N and 738.9 N at 0.7 MPa, peaking at 128.1 kgf theoretical, with cycling anywhere between 30 and 800 mm/s on 0.15-1.0 MPa (22-145 psi) air.
A vertically hung part of about 32 kg sits comfortably inside this cylinder once a 2:1 lift margin is applied to its 0.5 MPa push rating. The riveted stainless tube plus hard-chrome plated 16 mm rod shrug off mild corrosion, the fixed anti-impact pads soften both ends of travel, and the magnet ships standard so CMSG, DMSG or EMSG switches clamp on for free position feedback.

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 MAJ40X160-100S Is Used
Pallet Stopper
Stops a roller pallet at a pick station; the 100 mm trim absorbs pick-station pitch changes without re-plumbing the air circuit.
Chip Conveyor Door
Slides the cleanout door on a CNC chip conveyor, with the standard magnet confirming the closed position through a DMSG switch.
Nest Lift
Raises a 30 kg nesting jig vertically at 0.5 MPa with margin in hand, guided by two side posts so the rod never sees lateral load.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-100S the Right Cylinder?
Below this bore, the MAJ32X160-100S still manages 402.2 N of push at 0.5 MPa; 40 mm is the ceiling of the MA bore range, so heavier jobs move up a series. Fit FA flange or LB foot hardware, or an I / Y rod knuckle where tooling demands it. Never count on the stop screw to arrest a load mid-travel or under air loss - it only limits the extend position, so design a separate restraint for vertical work. Long 160 mm travel plus any lateral shock call for external guiding.
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 MAJ40X160-100S FAQ
Yes: 628.3 N push and 527.8 N pull at 0.5 MPa; 879.6 N push and 738.9 N pull at 0.7 MPa; 128.1 kgf theoretical peak force. The 160 mm extend stroke is trimmable across the ordered 100 mm window, down to a 60 mm extend, using the external stop screw.
No. Every MA-series cylinder leaves the factory with a piston magnet already fitted, so CMSG, DMSG and EMSG reed or hall switches mount directly on the barrel body as standard accessories - no special-order piston or retrofit is needed.
