Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 300mm 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 MACJ16X300-75S
Adjustability is the headline here: the MACJ16X300-75S gives a 300 mm extend stroke with a wide 75 mm trimming window, so one cylinder covers several product lengths. It is double-acting with a variable air cushion at both ends, built on a riveted stainless barrel with a hard-chrome carbon-steel rod. AirTAC rates the 16 mm bore at 100.5 N push and 86.4 N pull at 0.5 MPa.
For sizing, treat the 100.5 N rating as a ceiling, not a target: a hair under 60 N of real work is the sensible budget at 0.5 MPa, and vertical lifts should stay near 5 kg with a 2:1 margin (the theoretical peak is about 10 kg). Washdown-prone and outdoor spots suit this build far better than painted minis. The magnet ships inside as standard equipment, so DMSG, EMSG or CMSG sensors bolt straight on.

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 MACJ16X300-75S Is Used
Filling line reject push-off
Knocks off-spec bottles from a conveyor lane at 0.5 MPa; the 75 mm window adapts to different bottle pitches.
Jig cap lifter
Lifts roughly 5 kg jig lids vertically with a 2:1 margin, using the long stroke to clear a deep fixture.
Curing cabinet gate
Opens and closes a vent gate in a humid oven room where painted minis corrode within months.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-75S the Right Cylinder?
If 60 N of practical force falls short, the 20 mm bore pushes 157.0 N and the 25 mm bore 245.3 N at 0.5 MPa. The wide 75 mm window covers coarse length changes; fine final positioning still needs an external stop. Remember the adjuster shortens extend travel only and holds nothing: with air off, the rod is free to move. FA flange and LB foot mounts, plus I and Y knuckles, cover most fixture layouts, and every unit carries the standard magnet for sensing. Related options: MAJ for a bumper-ended adjustable build, MACD for a double-rod job.
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 MACJ16X300-75S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N push and 120.9 N pull. The peak theoretical rating is 20.5 kgf at 1.0 MPa. Air supply must stay within 0.15-1.0 MPa (22-145 psi).
The rolled stainless tube with its hard-chrome 6 mm rod resists rust and mild chemicals, so it survives washdown, humid plants and outdoor exposure that would pit painted mini cylinders. The covers are aluminium alloy with a stainless steel block.
