Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 40mm 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 MACJ16X40-30S
A 30 mm adjustment window gives this MACJ16X40-30S room to spare: the external stop screw can pull the extend stroke back from the full 40 mm to as little as 10 mm, while the variable air cushion at each end soaks up end-of-stroke shock. As a double-acting 16 mm bore it pushes 100.5 N and pulls 86.4 N at 0.5 MPa, climbing to 140.7 N on the extend side at 0.7 MPa.
Build quality is where the MA series earns its keep: a riveted stainless round barrel, aluminium covers and a hard-chrome plated 6 mm rod that shrugs off washdown and outdoor damp. Budget about 60 N of that 0.5 MPa push for real work rather than the full rating, which suits light part ejection and small clamping heads. The magnet is built in as standard, so CMSG / DMSG / EMSG switches mount without ordering a special piston, and the supply range runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MACJ16X40-30S Is Used
Bottle reject kicker
Flicks off-spec 250 ml PET bottles off a filling-line transfer plate; the 30 mm trim window absorbs conveyor pitch changes and about 60 N of usable push is ample for a 40 g bottle.
Vial tray indexing
Advances a small tray one pocket at a time in a lab filler; the variable cushion at both ends stops glass from ringing and the standard magnet feeds end-of-travel feedback to the PLC.
Blister carton flap tuck
Tucks a flap on a cosmetic blister line at up to 800 mm/s, with the stainless barrel coping with daily wipe-downs between product changeovers.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-30S the Right Cylinder?
Bore 16 sits at the bottom of the MA ladder - if 100.5 N at 0.5 MPa feels tight for the job, the next rung is a 20 mm bore pushing 157 N under the same supply. The stop screw is a mechanical end stop for the extend side only; if the plant loses air the rod drifts, so add a valve or external brake where holding matters. Mount it FA flange or LB foot, add an I or Y rod knuckle for pivoting loads, and note the M5x0.8 ports plus M6x1.0 male rod thread.
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 MACJ16X40-30S FAQ
At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N. Theoretical maximum is 20.5 kgf at 1.0 MPa. The adjustable window is 30 mm, so the 40 mm extend stroke can be shortened by the stop screw, and a variable air cushion is fitted at both ends. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Yes - every MA cylinder ships with the piston magnet built in, so CMSG, DMSG and EMSG switches clip onto the stainless barrel without a special-order piston. Ports are M5x0.8 on this 16 mm bore.
