About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-40S
Where a machine needs a final position you can nudge without re-plumbing, the MAJ16X300-40S trims its 300 mm extend stroke across a 40 mm window using an external stop screw. This bore 16 unit pushes 100.5 N and pulls 86.4 N at 0.5 MPa; at 0.7 MPa the figures reach 140.7 N and 120.9 N.
Weigh a light duty against those numbers: keep continuous work near 60 N and the rod will lift about 5 kg vertically with a 2:1 margin. The fixed bumper pad softens stroke-end impact (deceleration only - adjustable air cushioning lives in the MAC family), and the riveted stainless round body with its chrome-plated rod tolerates splashes in washdown corners.

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 MAJ16X300-40S Is Used
Lid-lift on a small sterilizer
Raises hinged sterilizer or oven lids of a few kilograms - with margin the rod lifts about 5 kg vertically at 0.5 MPa.
Label applicator press
Presses labels onto jars on a bottling bench, working near 60 N continuous force at 0.5 MPa supply.
Dosing head fine-set
The 40 mm window lets a technician fine-set dispensing height on a filling head without shimming the bracket.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-40S the Right Cylinder?
Start with the load: bore 16 gives 100.5 N at 0.5 MPa and is the entry size, so step up to bore 20 (157 N at 0.5 MPa) if your force budget is tight. Over a 300 mm stroke, keep side loads off the 6 mm rod - an I or Y knuckle plus FA flange or LB foot mounting keeps the pin aligned. The stop screw is a mechanical end stop for the extend stroke, not a clamp: with air lost, something external can still shove the rod back. The standard magnet leaves the cylinder sensor-ready.
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 MAJ16X300-40S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 120.9 N; theoretical peak at 1.0 MPa is 20.5 kgf. The 6 mm rod has an M6x1.0 male thread and air supply connects via M5x0.8 ports.
No. The MAJ16X300-40S carries fixed anti-impact pads that soften the last part of travel; they decelerate but are not tunable air cushions. If adjustable cushioning is required, AirTAC's MACJ family adds it on top of the adjustable stroke.
