Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MACJ32X80-50S
Need to fine-tune a stroke on the machine rather than on paper? The MACJ32X80-50S carries a 50 mm adjustable window: an external stop screw shortens the extend stroke in service, while a variable cushion at each end takes the sting out of the final approach. It is double-acting, runs 0.15-1.0 MPa (22-145 psi) and hits 402 N push at 0.5 MPa.
Its riveted round body (stainless tube, aluminium covers, hard-chromed rod) keeps sealing surfaces clean in humid plants. Rated 82 kgf theoretical maximum, it still does real work at about 241 N once you budget a sensible margin, and the standard magnet means position switches are never a special order.

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 MACJ32X80-50S Is Used
Pallet label kicker
Kicks label applicator arms into position; the 50 mm window absorbs tolerance drift between pallet sizes without bracket shimming.
CNC bar feeder stop
Positions bar stock against a stop in a small lathe feeder; mechanical trim matches new stock diameters in minutes on the shop floor.
Sorting gate actuator
Swings a diverter gate on a parts sorter; the adjustable extend stop sets gate travel precisely and cushions quiet the gate landing.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-50S the Right Cylinder?
Compare with the 25 mm version at 245 N before committing, since many light feeds are over-cylindered, and remember the 40 mm MACJ reaches 628 N at the same pressure if loads grow. Mount via FA flange or LB foot; the adjuster sets extend length but does not act as a brake, so use a valve or external stop where holding matters.
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 MACJ32X80-50S FAQ
Expect 402 N push and 346 N pull at 0.5 MPa, and 563 N push with 484 N pull at 0.7 MPa, peaking at 82 kgf theoretical at 1.0 MPa. Stroke is adjustable over 50 mm, cycle speed spans 30-800 mm/s, and the 1/8-inch port suits typical shop air lines.
No. The stop screw sets extend length mechanically; it is not a load lock, so with air lost the rod can still drift. Use switching valves or an external latch where position must persist. The dual air cushions, meanwhile, simply soften end-of-stroke impact.
