About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-50S
A compact double-acting mini cylinder with a 250 mm stroke that can be shortened on the machine by up to 50 mm through an external stop screw. The 16 mm bore produces 100.5 N of push at 0.5 MPa (and 140.7 N at 0.7 MPa), enough for light clamping, ejecting and sorting tasks at speeds from 30 to 800 mm/s.
The riveted stainless round barrel with a hard-chrome plated carbon-steel rod stands up to washdown and damp plant air far better than painted minis. Plan on roughly 60 N of usable work at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches mount without special orders.

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 MAJ16X250-50S Is Used
Light ejection on a long reach
Pushing finished cosmetic cartons off a small conveyor end-stop where 100 N class force and a 50 mm shorter extend stroke clear the transfer table.
Sample lift in lab automation
Raising a 300 g sample tray between analyzer decks; about 5 kg of vertical lift capacity leaves ample margin at 0.5 MPa.
Height-sorted divert gate
Trimming the stop screw between product runs so a diverting gate rises to just the right height for each package family.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-50S the Right Cylinder?
At 100.5 N push at 0.5 MPa this bore 16 suits light work; if your real demand climbs past about 60 N, step up to MAJ20 (157 N) or MAJ25 (245.3 N) at the same pressure. With a 250 mm stroke and a 6 mm rod, keep side loads off the piston and guide the load externally to protect the slender rod. The stop screw is a stroke end-stop, not a mid-stroke lock - on air loss the piston can drift, so never rely on it to park a load. Mount FA flange or LB foot; position sensing is built in thanks to the standard magnet.
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 MAJ16X250-50S FAQ
At 0.5 MPa the 16 mm bore 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. The theoretical maximum is 20.5 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
A stainless-steel barrel carries a hard-chrome plated carbon-steel rod, with aluminium-alloy covers riveted on - a round, compact package that resists washdown and mild corrosion. The built-in magnet is standard, so CMSG / DMSG / EMSG switches clamp on without special ordering.
