Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 150mm 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 MACJ16X150-20S
Cushioned, trimmable and compact, this MACJ pairs a 150 mm extend stroke with a 20 mm on-site trim window and a variable air cushion at each end, so end-of-travel shock stays low even near the 800 mm/s speed ceiling. Double-acting on 0.15-1.0 MPa (22-145 psi), the 16 mm bore produces 100.5 N push and 86.4 N pull at 0.5 MPa, enough to lift about 5 kg vertically with a 2:1 margin.
The rolling-packed body combines a stainless barrel, a hard-chrome plated 6 mm rod and aluminium covers, standing up to splashes that would rust painted minis. Its standard-fit magnet drives CMSG, DMSG or EMSG switches for repeatable end-position detection.

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 MACJ16X150-20S Is Used
Guard door latch actuator
A light interlock plunger on a machine guard, with the standard magnet and an EMSG switch proving the door is positively opened at each cycle.
Sample carousel indexing
Advancing a small rotary sample carousel in an analytical instrument, where the 20 mm trim window aligns each station after refits.
Checkweigher reject arm
Tipping light underweight packs off a checkweigher belt with 100.5 N at 0.5 MPa, the dual cushions damping the kick at speed.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-20S the Right Cylinder?
If 100.5 N push at 0.5 MPa falls short, the 20 mm MA bore reaches 157.0 N and the 25 mm bore 245.3 N at the same pressure, so size by measured load rather than guesswork. At 150 mm of stroke, keep side loads off the 6 mm rod with external guides or an I or Y knuckle. Do not count on the stop screw to park a load: it sets the extend limit only, and the rod coasts if pressure vanishes. FA flange and LB foot fixings, PT threads standard with G and NPT variants.
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 MACJ16X150-20S 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; theoretical maximum 20.5 kgf at 1.0 MPa. Bore 16 mm, stroke 150 mm with a 20 mm adjustable extend window, double-acting, variable air cushion both ends, 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
No. Every MA-series cylinder, including this one, ships with the magnet built in as standard. CMSG, DMSG and EMSG reed or hall-effect switches mount directly on the stainless barrel, giving you end-of-stroke or intermediate position signals without any custom piston or price bump.
