About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X45-40S
Double acting with an adjustable extend stroke, this 16 mm bore unit trims its extend travel anywhere inside a 40 mm window via an external stop screw. At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push reaches 140.7 N, and the theoretical ceiling is 20.5 kgf at 1.0 MPa. Budget roughly 60 N of real work at 0.5 MPa and the sizing stays conservative.
The body is AirTAC's riveted MA platform: a stainless-steel round barrel, a 6 mm hard-chrome plated carbon-steel rod, aluminium covers and fixed anti-impact bumper pads that soften stroke-end impact (deceleration only, not an adjustable air cushion). A magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on without a special piston. Port is M5x0.8; speed range 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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X45-40S Is Used
Benchtop filler eject pin
Ejects capped vials off a small pharma bench filler; the 40 mm trim lets the operator dial the push-off point to the tray height.
Test fixture pusher
Presses a sample button on an electronics test rig, where 100.5 N at 0.5 MPa is plenty and the stainless barrel shrugs off a humid, frequently wiped-down bench.
Slide gate latch
Kicks a light sliding guard gate closed on a packaging bench; the built-in magnet feeds a CMSG switch to confirm the closed position.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X45-40S the Right Cylinder?
Below 100 N at 0.5 MPa there is no smaller MA bore, so if the load exceeds the roughly 60 N comfortable margin, step up to a 20 mm bore (157.0 N push) or a 25 mm bore (245.3 N push). Keep external side loads off the 6 mm rod and guide the workpiece if it tends to twist.
Mount with an FA flange or LB foot, and add I or Y rod knuckles where alignment is imperfect. The stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: with air lost, the piston can still drift.
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 MAJ16X45-40S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N. At 0.7 MPa those figures rise to 140.7 N push and 120.9 N pull, and the theoretical maximum at 1.0 MPa is 20.5 kgf. Fluid is filtered air at 0.15-1.0 MPa (22-145 psi).
No. Every MAJ ships with a built-in magnet as standard, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel for end-of-stroke signalling, no special-order piston needed.
