About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-50S
Fifty millimetres of stroke adjustment is built into the MAJ16X300-50S: turn the external stop screw and the extend stroke lands anywhere within that 50 mm window below the full 300 mm. Force at this bore 16 size is 100.5 N push / 86.4 N pull at 0.5 MPa, or 140.7 N / 120.9 N with a 0.7 MPa supply.
Because AirTAC magnets every MA cylinder as standard, CMSG / DMSG / EMSG switches mount on the barrel with no special-order piston - useful when the trimmed stroke shifts your end positions. The rolled stainless barrel and hard-chrome 6 mm rod also shrug off washdown and outdoor damp; budget around 60 N for continuous work, roughly a 5 kg vertical lift at half rating.

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 MAJ16X300-50S Is Used
Vision station reject gate
Swings a reject flap on a bottling QC station; the 50 mm window tunes the gate's open angle to the lane width.
Drawer latch actuator
Locks and unlocks storage drawers in an automated tool crib using gentle 60 N-class force at 0.5 MPa.
Pallet stop on an assembly fixture
Stops small pallets at an operator station; the trimmed stroke matches fixture gauge blocks exactly.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-50S the Right Cylinder?
Compare siblings before ordering: bore 16 (100.5 N at 0.5 MPa) is the lightest in the range, while bore 20 lifts the rating to 157 N if 60 N of working force falls short. FA flange and LB foot are the catalog mounts; I and Y knuckles suit pivoting rod eyes. Across 300 mm, treat the slender 6 mm rod gently - keep side loads low or externally guide the load. Note that the adjuster ends the extend stroke mechanically; it will not hold a load against a losing air supply.
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 MAJ16X300-50S FAQ
At 0.5 MPa: 100.5 N extending, 86.4 N retracting. At 0.7 MPa: 140.7 N extending, 120.9 N retracting. Theoretical maximum at 1.0 MPa is 20.5 kgf. Supply runs 0.15-1.0 MPa (22-145 psi) with speed from 30 to 800 mm/s.
The round barrel is stainless steel and the 6 mm rod is hard-chrome plated carbon steel, a combination that resists mild corrosion far better than painted mini cylinders. Aluminium-alloy covers are rolled onto the tube, keeping the riveted body compact.
