About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X25-20S
With a 20 mm trim window on a 25 mm stroke, this double-acting MAJ covers extend lengths from 5 to 25 mm once the stop screw is set. Bore 16 output is modest but honest: 100.5 N out, 86.4 N back at 0.5 MPa, or 140.7 / 120.9 N if you push supply to 0.7 MPa. Feed it 0.15-1.0 MPa (22-145 psi) and it cycles 30-800 mm/s.
Do the gravity math on the push rating and the rod raises about 10 kg vertically at face value; halve it for a 2:1 margin and you have roughly 5 kg of vertical lift to match against real part weights. The riveted stainless round body with a hard-chrome plated rod shrugs off splash and humidity, and the fixed bumper pad absorbs stroke-end shock - a deceleration pad, not the adjustable cushion the MAC family carries.

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 MAJ16X25-20S Is Used
PCB fixture lid latch
A 5-25 mm extend range latches test-fixture lids on ICT racks, with a DMSG switch wired to interlock the tester before cycling.
Dispense needle set
Trims the z-stroke of a micro-dispenser so the 6 mm rod lowers a needle to glue height on small housings.
Connector crimp preform
Pre-aligns crimp terminals with light sub-100 N pressure before a mechanical press does the heavy forming.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X25-20S the Right Cylinder?
Nothing in the MA line is smaller than this 16 mm bore, so if 100.5 N at 0.5 MPa undershoots your load, the next step is bore 20 at 157 N push. The adjuster is a mechanical end stop for extend only - on air loss the piston still settles, so pin critical positions with a sensor or external clamp. FA flange, LB foot and I / Y rod knuckles cover the fixings; the standard magnet pairs with CMSG / DMSG / EMSG switches.
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 MAJ16X25-20S FAQ
The rolled stainless tube plus hard-chrome plated rod resist corrosion in damp, food-adjacent or outdoor cells where painted minis pit. Covers are aluminium alloy, the compact round body is riveted rather than tie-rod assembled, and the magnet ships standard for CMSG / DMSG / EMSG switches.
Push 100.5 N and pull 86.4 N at 0.5 MPa; push 140.7 N and pull 120.9 N at 0.7 MPa; theoretical maximum 20.5 kgf at 1.0 MPa. Stroke is 25 mm with a 20 mm extend-trim window, speed 30-800 mm/s, ports M5x0.8, rod 6 mm with M6x1.0 male thread.
