About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-75S
A 75 mm trim window gives the MACJ16X125-75S the widest tuning range in the small-bore group: set the extend stop anywhere within 75 mm and re-set it as the product changes. The cylinder is double-acting with an adjustable stroke and a variable air cushion at both ends.
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N at 0.7 MPa; size continuous duty near 60 N. Because the body is a riveted stainless round barrel with a hard-chrome rod, it survives damp, dusty corners where aluminium minis pit. The built-in magnet is standard, ready for CMSG, DMSG or EMSG switches.

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 MACJ16X125-75S Is Used
Reject fingers on bottle lines
Swing lightweight rejects off the conveyor; the stainless barrel wipes clean between washdown shifts.
Print registration stop
Trim the stop within 75 mm as job sizes change, cushioning each arrival to keep registration steady.
Nozzle lift on filling bench
Lift a light dispensing head with an equivalent of about 5 kg vertical capacity, retracting under 86.4 N of pull.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-75S the Right Cylinder?
Bore 16 tops out at 100.5 N at 0.5 MPa; when the load needs more, bore 20 gives 157 N and bore 32 gives 402.2 N at the same pressure. Treat the adjuster as an extend-stroke end stop only - it is not a brake, and the rod will drift if air pressure is lost. FA flange and LB foot mounts are listed, I and Y knuckles suit pivoting loads, and use the cushion before running near 800 mm/s.
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 MACJ16X125-75S FAQ
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; 20.5 kgf theoretical maximum at 1.0 MPa. Bore is 16 mm with a 6 mm rod and an M5x0.8 port.
Within the ordered 75 mm window the extend stroke can be shortened to any point short of the full 125 mm; it can never exceed the ordered stroke. The trim is a mechanical stop, not a load lock, so use a valve if the load must stay put without air.
