Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X200-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X200-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 200mm stroke, 1/8" 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 MACJ20X200-75S
Double-acting and adjustable, the MACJ20X200-75S trims its extend stroke on site across a 75 mm window while variable air cushions soften both ends of travel. A riveted stainless round barrel carries a hard-chrome plated carbon-steel rod, so the body shrugs off washdown and damp workshop air better than painted minis. The 8 mm rod takes an M8x1.25 male thread, air connects through 1/8 in. ports, and the speed range runs 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
At 0.5 MPa (73 psi) this 20 mm bore pushes 157 N with 131.9 N back on the pull side; at 0.7 MPa (102 psi) the push climbs to 219.8 N, and the theoretical ceiling is 32 kgf at 1.0 MPa (145 psi). For real sizing, count on roughly 94 N of useful work at 0.5 MPa (73 psi), which lifts about 8 kg vertically with a 2:1 margin. A piston magnet ships as standard, so CMSG, DMSG or EMSG switches clip on without any special-order piston.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MACJ20X200-75S Is Used
Bowl ejector
Kicks small machined parts off a sorting conveyor at up to 800 mm/s, with the 75 mm window letting operators fine-tune eject timing without re-piping.
Sample slide pusher
Moves lab sample trays a set 200 mm into an analyzer station; the stainless barrel tolerates wipe-down on wet benches that rust painted bodies.
Jig latch
Slides a drill-jig clamp shut on light steel brackets, working comfortably under the 94 N practical force level at 0.5 MPa (73 psi).
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X200-75S the Right Cylinder?
Between the 16 mm bore (100.5 N push at 0.5 MPa (73 psi)) and the 25 mm bore (245.3 N), this 20 mm size sits mid-range for light slide and eject duty. Note that the stop screw sets the extend endpoint mechanically only; on air loss the rod can still drift, so use a blocking valve where holding matters. FA flange and LB foot mountings plus I and Y rod knuckles cover most fixings, and the standard magnet suits CMSG or DMSG sensing. At 200 mm of travel, keep side load low or guide the load externally to protect the 8 mm rod.
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 MACJ20X200-75S FAQ
At 0.5 MPa (73 psi) it pushes 157 N and pulls 131.9 N; at 0.7 MPa (102 psi) push is 219.8 N and pull 184.7 N, with a 32 kgf theoretical maximum at 1.0 MPa (145 psi).
The variable cushion at each end absorbs deceleration, so you can push harder within the 30-800 mm/s range without hammering the aluminium covers. The riveted stainless barrel plus hard-chrome rod also resists washdown better than painted mini bodies.
