About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-10S
Where product sizes differ by only a few millimetres, the -10 window on the MACJ16X125-10S is all the trim you need: set the extend stop anywhere from 115 to 125 mm and lock it. Double-acting piston, variable air cushion at each end, 0.15-1.0 MPa (22-145 psi) supply and a speed band of 30-800 mm/s.
The two-way piston seal doubles as a grease store, cutting maintenance on this stainless round-body unit. Output is 100.5 N push and 86.4 N pull at 0.5 MPa - the vertical-lift view is easier: about 5 kg lifted with a 2:1 margin. The 6 mm rod carries 20 um of hard chrome, and the standard-fit magnet accepts CMSG / DMSG / EMSG switches with no special-order piston.

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 MACJ16X125-10S Is Used
Label press roller on a bottle labeler
The 10 mm window soaks up bottle-to-bottle diameter differences on a rotary labeler; 100.5 N holds the label firm while the cushion ends any roller bounce.
PCB test fixture probe
Presses a test probe onto contact pads on an electronics bench fixture; about 60 N of working force at 0.5 MPa protects fine pads from over-pressing.
Part-presence flip arm
Swings a small feeler arm across a parts chute to confirm presence; the magnet reports the flipped state to the PLC through a CMSG or DMSG switch.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-10S the Right Cylinder?
This is the entry force class of the MA range; if the load outgrows 100.5 N push / 86.4 N pull at 0.5 MPa, step to bore 20 for 157.0 N / 131.9 N at the same pressure. At a 125 mm stroke the 6 mm rod is the weak link against buckling and side thrust, so support long or overhung loads with external guides rather than the cylinder itself. FA flange and LB foot mounts, plus I and Y knuckles, cover most fixtures. The trim stop is a mechanical end stop for the extend side, not a mid-stroke lock - the rod will settle if pressure disappears.
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 MACJ16X125-10S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N and 120.9 N; theoretical peak is 20.5 kgf at 1.0 MPa. Derate for real work: around 60 N of usable push at 0.5 MPa, enough to lift about 5 kg vertically at a 2:1 margin.
The barrel is stainless steel and the aluminium covers are rolled onto it, sealing the body; the 6 mm carbon-steel rod carries 20 um of hard chrome against rust and wear. Operating range spans -20 to +70 C with air filtered to 40 um, so coolants and misty food-plant air are not a problem.
