Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X80-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X80-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 80mm stroke, 1/4" 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 MACJ50X80-10S
Built as AirTAC's own riveted round-body mini - stainless barrel, hard-chrome plated carbon-steel rod, rolled aluminium covers - the MACJ50X80-10S puts out 981 N at 0.5 MPa on extend and 881 N on retract. A compact 10 mm window lets maintenance trim the extend stop in minutes when the fixture needs a shorter hit.
Both ends carry a variable air cushion, so the rod lands quietly even at higher speeds, and the standard built-in magnet means a CMSG / DMSG / EMSG switch can be added without any special piston. In practice, size the job to about 589 N of real working force at 0.5 MPa rather than the raw 981 N rating, and the cylinder will run cool and last longer.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X80-10S Is Used
Rinser reject gate
Swings a reject paddle at a bottle rinser outlet; the 10 mm trim is just enough to match two bottle formats without re-tubing the air line.
Pallet strapper clamp
Pinches strap loops on a semi-auto strapper head - 981 N at 0.5 MPa clamps firmly while the cushion protects the clamp shoe.
Vise kicker on a drill bench
Advances a part stop on a machining bench; the stainless barrel resists the cutting-fluid mist that flakes painted mini cylinders.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X80-10S the Right Cylinder?
Where a task needs under 600 N, the 40 mm bore (628 N at 0.5 MPa) saves money; past 1400 N, the 63 mm bore (1558 N) is the honest choice. Remember the screw only limits where extend finishes - drop air pressure and the rod is free to move, so it is no brake. Mount via FA flange or LB foot, add I or Y rod knuckles if the load pivots, and order PT, G or NPT ports; the magnet is already inside for sensor fitment.
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 MACJ50X80-10S FAQ
Yes: push 981 N / pull 881 N at 0.5 MPa, push 1374 N / pull 1233 N at 0.7 MPa, and 200 kgf theoretical maximum at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, with the extend stroke adjustable across the 10 mm window.
A high-precision stainless-steel tube, a hard-chrome plated 16 mm rod, and a two-way piston seal that also stores grease - the combination resists corrosion and keeps lubrication alive between services.
