About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X150-40S
A compact round-body actuator for tight spots, the MAJ16X150-40S pairs a 16 mm stainless barrel with a hard-chrome plated 6 mm carbon-steel rod and an external stop screw that shortens the 150 mm extend stroke anywhere inside a 40 mm window. Double-acting throughout, it runs on filtered air at 0.15-1.0 MPa (22-145 psi), cycles at 30-800 mm/s, and feeds through M5x0.8 ports.
At 0.5 MPa this bore pushes with 100.5 N and pulls with 86.4 N, so plan real duty around 60 N to keep margin in hand. The 10.2 kgf theoretical lift at full pressure translates to about 5 kg of vertical lifting once a 2:1 margin is applied - enough to raise a small machined bracket or loaded sensor head. Fixed bumper pads soften stroke-end shock, and the built-in magnet is standard, so CMSG / DMSG / EMSG switches clip straight on with no special-order piston.

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 MAJ16X150-40S Is Used
Cap ejection
Ejects small injection-molded caps or bushings from a fixture nest, using the trimmed 40 mm window to match the part depth exactly.
Sample shuttle
Slides lab sample trays between two test stations, with a CMSG switch confirming home position on the standard magnet.
Test lid lift
Raises a light inspection lid - sized against the 100.5 N push at 0.5 MPa, this bore lifts about 5 kg vertically with a 2:1 margin.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X150-40S the Right Cylinder?
With 100.5 N at 0.5 MPa, bore 16 is the smallest in the MA range - step up to the 20 mm bore (157.0 N at 0.5 MPa) or the 25 mm bore (245.3 N) if your load outgrows it. Rod thread is M6x1.0 on the 6 mm rod.
The stop screw is a mechanical end stop for the extend stroke only, not a load-holding brake: if air pressure is lost, the piston still drifts. Mount with the FA flange or LB foot, add I or Y rod knuckles as needed, and at 150 mm of travel guide any side load externally rather than letting the slender 6 mm rod take it.
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 MAJ16X150-40S FAQ
At 0.5 MPa it pushes with 100.5 N and pulls with 86.4 N. At 0.7 MPa those figures rise to 140.7 N and 120.9 N, and the theoretical maximum is 20.5 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
An external stop screw on the MAJ16X150-40S shortens the extend stroke to any point within the ordered 40 mm window; the retract stroke stays at full 150 mm. It is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Fixed bumper pads cushion both ends of travel.
