Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S
Short-travel positioning is where this MACJ16X25-10S earns its place: a 25 mm stroke you can shorten by up to 10 mm, double-acting with cushioning at both ends. The 16 mm bore yields 100.5 N push and 86.4 N pull at 0.5 MPa - about 60 N once you derate for real work, enough to seat connectors or clamp light parts.
Inside is AirTAC's MA architecture: a stainless round barrel riveted to aluminium covers, a hard-chrome 6 mm rod, and a grease-retaining piston seal. The magnet comes built in as standard, so CMSG / DMSG / EMSG switches detect position without modification. Rated 0.15-1.0 MPa (22-145 psi), proof tested at 1.5 MPa (215 psi), it cycles at 30-800 mm/s.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S Is Used
Connector press on a PCB fixture
Seats board-to-wire connectors with about 60 N of working force; the 10 mm trim fine-tunes seating depth after the fixture is built.
Vial stopper tapper on a filling line
Nudges stoppers home on small vials; dual cushions keep the tap gentle even at the top of the 30-800 mm/s range.
Z-height confirmation probe
Taps a test point and retracts over 25 mm; the built-in magnet with a CMSG switch proves full seat on every cycle.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S the Right Cylinder?
For these forces the next size up is bore 20 at 157.0 N push (0.5 MPa) or bore 25 at 245.3 N; there is nothing smaller in the MA range. Mount via FA flange or LB foot and pick an I or Y knuckle if the load pivots. The 10 mm stop screw trims extension only - under lost air the piston is free to move, so hold loads with valving instead. Port is M5x0.8 and the male rod thread is M6x1.0.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-10S FAQ
Push 100.5 N and pull 86.4 N at 0.5 MPa; 140.7 N and 120.9 N at 0.7 MPa; 20.5 kgf theoretical peak at 1.0 MPa. Stroke is 25 mm with a 10 mm extend-side adjustment, twin variable cushions, speed 30-800 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi) and proof at 1.5 MPa (215 psi).
Yes on both counts. Cushion screws at each end let you slow the last millimetres of travel, protecting light fixtures from repeated shock, and every MACJ leaves the factory with an internal magnet so CMSG, DMSG and EMSG range switches fit straight onto the barrel.
