Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X30-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X30-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 30mm 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 MACJ16X30-30S
Where a light, exact push matters more than brute force, this 16 mm bore MACJ earns its slot. Double-acting, with a 30 mm extend stroke you can shorten anywhere inside the 30 mm adjustable window, plus a variable air cushion at both ends so faster cycles will not hammer the covers. Expect 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa; 20.5 kgf is the theoretical maximum at 1.0 MPa.
For honest sizing, treat about 60 N as the usable working force at 0.5 MPa. The riveted stainless barrel and hard-chrome plated rod stand up to frequent wipe-downs, a real advantage in food-adjacent and damp corners. The magnet is built in as standard equipment, so CMSG, DMSG or EMSG switches bolt on without ordering a sensing variant. Supply runs at 0.15-1.0 MPa (22-145 psi) with speeds of 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 MACJ16X30-30S Is Used
PCB ejector after wave solder
Lifts finished boards off the conveyor finger rail; 100.5 N push at 0.5 MPa handles a loaded 200 x 150 mm panel with room to spare.
Sample tube indexer
Advances sample tubes one station at a time in a lab autosampler; the 30 mm window trims the pitch position without reclocking the drive.
Guard door push on a bench machine
Slides a lightweight polycarbonate guard shut before cycle start; a DMSG switch confirms the closed position through the standard magnet.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X30-30S the Right Cylinder?
There is no smaller bore in the range, so 16 mm and its 100.5 N push at 0.5 MPa is the floor; if that is tight, the 20 mm bore delivers 157.0 N. The adjuster is purely a mechanical end stop for the extend stroke - a piston that loses air can still settle, so use a proper clamp when position must hold under load. Choose an FA flange or LB foot for the base, or I and Y rod knuckles for a pivoting link. On this short 30 mm frame with a 6 mm rod, side loads are a non-issue.
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 MACJ16X30-30S FAQ
At 0.5 MPa: 100.5 N push and 86.4 N pull. At 0.7 MPa: 140.7 N push and 120.9 N pull. The theoretical maximum at 1.0 MPa works out to 20.5 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi), with an M5x0.8 port and an M6x1.0 rod thread.
FA flange and LB foot brackets cover fixed installations, while I and Y rod knuckles handle pivoting links; note the adjustable-stroke version offers no SDB or back-cover code. The variable air cushion at each end is set by the flow control on the cover, letting you soften landings as speed or load changes anywhere in the 30-800 mm/s range.
