Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-20S 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 MACJ32X150-20S
Machine builders who reshuffle layouts get breathing room from the MACJ32X150-20S: shorten the extend stroke by up to 20 mm on site when a fixture moves or the part changes, no cylinder swap needed. Air drives both strokes and variable cushions at each cover tame arrivals at up to 800 mm/s. The 32 mm bore delivers 402 N extend and 346 N retract at 0.5 MPa.
The full 402 N converts to about 41 kg of vertical lift; apply a 2:1 margin and the cylinder handles around 20 kg of real lifted weight, with continuous push nearer 241 N. Construction is the riveted round-body MA build - stainless barrel, hard-chrome plated 12 mm rod - that outlasts painted minis in wet or dusty cells. Every unit ships with its magnet, so CMSG / DMSG / EMSG sensing costs nothing extra.

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 MACJ32X150-20S Is Used
Tray divider push
Push trays into sortation lanes with 241 N of practical force; retune the final 20 mm whenever tray height changes.
Sample lift in a benchtop analyzer
Lifts about 20 kg vertically with a safety margin - comfortable for reagent carousels and sample trays in compact lab units.
Small press pre-clamp
Pre-clamp workpieces before a hand press; 563 N at 0.7 MPa adds real holding force without buying a full press stage.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X150-20S the Right Cylinder?
Compare options: the MACJ32X150-30S widens the trim to 30 mm, the MAC32X150 drops the adjuster for fixed travel, and the MAJ32X150 swaps cushioning for bumpers. Downsize to bore 25 (245 N at 0.5 MPa) or upsize to bore 40 (628 N) as the load dictates. FA flange or LB foot, plus I or Y knuckles on the M10x1.25 rod thread. If the load must hold position on air failure, fit a locking valve - the 20 mm stop only limits extend travel, and the piston will creep with air off. 1/8 ports, 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
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 MACJ32X150-20S FAQ
Count on 402 N extend and 346 N retract at 0.5 MPa, or 563 N and 484 N at 0.7 MPa; the ceiling is roughly 82 kgf theoretical at 1.0 MPa. Practical continuous push is nearer 241 N once a normal design margin is applied.
The barrel is stainless steel and the 12 mm piston rod is carbon steel with a 20 um hard-chrome plate; aluminium covers are rolled and riveted onto the tube. That combination handles coolant mist, washdown splashes and outdoor dust far better than painted mini cylinders.
