About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X85-20S
An 85 mm stroke paired with a 20 mm trim window makes this 16 mm bore MAJ easy to dial in on jigs where the exact extend length is only settled during commissioning. Push force at 0.5 MPa is 100.5 N; budget around 60 N for the actual job and count on lifting roughly 5 kg vertically with a 2:1 safety margin.
Its riveted round body pairs a stainless barrel with a hard-chrome carbon-steel rod, so splashes, humidity and outdoor exposure cause far less trouble than on painted minis. The bumper pads are fixed anti-impact type - they soften the stroke end but are not an adjustable cushion. The standard magnet accepts CMSG, DMSG or EMSG switches out of the box.

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 MAJ16X85-20S Is Used
Kicker on a benchtop conveyor
Tips lightweight cartons off a small belt line; the 20 mm window absorbs minor product-size changes without re-plumbing the machine.
Index pin on a rotary dial table
Locks each station with about 60 N of net push force at 0.5 MPa, the trim screw setting the exact pin projection into the cam plate.
Tray presentation in a parts feeder
Slides a tray of fasteners into pick position; the wipe-clean stainless barrel copes with the oily feeder environment better than painted bodies.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X85-20S the Right Cylinder?
Bore 16 is the floor of the MA range; the 20 mm bore reaches 157 N at 0.5 MPa if the load grows. Mount by FA flange or LB foot, with I and Y knuckles available for rod-side articulation. Note the trim screw shortens the extend stroke only and holds nothing once air is removed - with pressure lost the rod is free to drift, so external locking is needed where a load must stay put.
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 MAJ16X85-20S FAQ
At 0.5 MPa expect 100.5 N push and 86.4 N pull; at 0.7 MPa, 140.7 N and 120.9 N. Maximum theoretical force at 1.0 MPa is 20.5 kgf. The port is M5x0.8, the rod thread M6x1.0 on a 6 mm rod, and the working pressure range is 0.15-1.0 MPa (22-145 psi).
The rolled, riveted round body keeps the MAJ slim and sealed, and stainless steel plus a 20 um hard-chrome rod resist mild corrosion and washdown that would chew up painted-steel minis. Fixed anti-impact pads cushion each stroke end, and the built-in magnet is standard equipment for CMSG / DMSG / EMSG sensing.
