Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 190mm 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 MACJ32X190-20S
Where the working throw is fixed but the exact stopping point keeps moving, the 20 mm adjust window on this MACJ32X190-20S lets technicians trim the extend stroke - anywhere within 20 mm of the 190 mm ordered stroke - with a stop screw, no re-piping required.
The bore pushes 402 N and pulls 346 N at 0.5 MPa; treat about 241 N as the practical pushing budget at that pressure, or think of it as lifting roughly 20 kg vertically once you halve the 41 kgf equivalent for a 2:1 margin. A variable cushion at both ends and the riveted stainless barrel with hard-chrome rod round out a compact, corrosion-resistant package.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X190-20S Is Used
Clamp-and-locate on a weld fixture
Swings a locating pin into a jig; the 20 mm window lets welders fine-tune pin depth between part revisions.
Print-head parking on a wide-format printer
Parks the carriage at a service station; cushioning at both ends stops the 190 mm travel without bounce.
Small-parts elevator on a feeder bowl
Raises a tray of fasteners with about 20 kg of vertical capacity at a 2:1 margin; the stainless body tolerates cutting-fluid mist.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-20S the Right Cylinder?
For lighter work, a MACJ25 bore gives 245 N push at 0.5 MPa; for heavier pushes, MACJ40 delivers 628 N. Mount on an FA flange or LB foot, and fit an I or Y knuckle if the 190 mm stroke must tolerate slight misalignment - long strokes and side loads bend thin rods fast.
Remember the stop screw only shortens the extend stroke and never holds position on lost air; use a blocking valve where the load must stay put. 1/8" ports, magnet standard.
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 MACJ32X190-20S FAQ
At 0.5 MPa: 402 N push, 346 N pull. At 0.7 MPa: 563 N push, 484 N pull. Theoretical maximum force is 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s with a 20 mm extend-trim window.
The rolled stainless tube and hard-chromed 12 mm rod resist corrosion from washdown, coolants and outdoor air - conditions that flake paint off steel-bodied minis. The heterogeneous piston seal also stores grease, extending service intervals.
