Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 150mm 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 MACJ32X150-50S
Need a 150 mm reach that can be dialed back by up to 50 mm on site? This 32 mm MACJ delivers 402 N forward and 346 N back at 0.5 MPa, climbing to 563 N and 484 N at 0.7 MPa, with the extend stroke set by an external stop screw anywhere inside the 50 mm window. A variable cushion at both ends lets faster speeds run without hammering the covers.
Riveted stainless barrel, hard-chrome carbon-steel rod, aluminium covers: this round-body mini tolerates the condensation and mild washdown that ruin painted-steel cylinders. The magnet comes standard, so CMSG / DMSG / EMSG switches mount straight on. Sizing from the numbers: treat about 241 N as the realistic continuous force at 0.5 MPa, and for vertical lifts the push force equals roughly 41 kg, halve it to about 20 kg for a 2:1 margin.

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 MACJ32X150-50S Is Used
Roller conveyor stopper gate
Rise-and-drop or swing stoppers between conveyor lanes use the 50 mm trim to match product pitch, with the cushion easing each stop of the passing carton.
Lid press on cosmetic trays
402 N at 0.5 MPa presses snap-on lids on 100 ml cosmetic trays; the 50 mm window accommodates two tray heights without re-plumbing the machine.
Small battery module elevator
The bore lifts roughly 20 kg vertically with a 2:1 margin, enough for raising coin-cell modules between an inspection station and the packing level.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-50S the Right Cylinder?
Step down to the 25 mm bore for 245 N push or up to the 40 mm bore for 628 N if the load changes; this 32 mm unit covers the middle ground at 150 mm, well inside the 500 mm standard-stroke limit for the bore. The stop screw only sets a shorter extend stroke and will not hold position against air loss, so add a blocking valve or external stop where loads must stay put. FA flange and LB foot plates, I and Y knuckles, and the standard magnet complete the ordering picture.
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 MACJ32X150-50S FAQ
Force is 402 N forward and 346 N return at 0.5 MPa, rising to 563 N and 484 N at 0.7 MPa, with a theoretical peak of 82 kgf at 1.0 MPa. The 150 mm stroke trims inside a 50 mm extend window; speed spans 30-800 mm/s at 0.15-1.0 MPa (22-145 psi) supply.
The stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock. If supply pressure drops, the piston can drift away from the set point, so use a blocking valve or an external mechanical stop wherever a load must stay held.
