Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm 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 MACJ63X80-30S
Where set-up changes shift to shift, a 30 mm trim window pays for itself: the stop screw on this 63 mm mini cylinder re-positions the extend stroke anywhere inside that range without touching a single fitting. Double-acting with a variable cushion at each end, it develops 1557.9 N push and 1457.4 N pull at 0.5 MPa, or 2181.0 N at 0.7 MPa, across 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
Plan on about 935 N of usable force at 0.5 MPa rather than the full rating, with vertical lift capability near 158 kg before any margin. Construction pairs a riveted stainless round tube and hard-chrome plated 16 mm rod with rolled aluminium covers - a package that shrugs off washdown - and the built-in magnet makes CMSG, DMSG or EMSG switch fitment a zero-cost choice.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X80-30S Is Used
Multi-depth taping heads on carton sealers
Retune stroke depth inside the 30 mm window when carton sizes change; about 935 N of working force at 0.5 MPa drives the head cleanly into the seam.
Clamp tooling on automotive weld fixtures
Trim the clamp approach so 2181.0 N at 0.7 MPa seats thick brackets without deforming thin-gauge jigs; both-end cushioning protects the frame.
Gate actuation in cold-store pick modules
Rated from -20 to +70 C, the stainless barrel and chrome rod handle freezer-area duty while the magnet feeds DMSG switches for gate feedback.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X80-30S the Right Cylinder?
Against the 50 mm bore (981.3 N push at 0.5 MPa), this 63 mm model carries about half again the push - useful when loads cycle fast or sit slightly off-axis. It is the ceiling of the MA series, so beyond this, run two cylinders in parallel. Pick FA flange or LB foot mounting, add I or Y knuckles where tooling links to the rod, and note that the adjuster only shortens extend travel: with air gone it holds nothing, so back up vertical weights independently.
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 MACJ63X80-30S FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; theoretical ceiling 317.7 kgf at 1.0 MPa. Base stroke 80 mm trimmed by a 30 mm adjustable window, air cushion at both ends, 1/4" ports, 16 mm hard-chrome rod, 0.15-1.0 MPa (22-145 psi) pressure and 30-800 mm/s speed.
FA flange and LB foot mounts are supported, along with I and Y rod knuckles for tooling links. The magnet comes standard, so CMSG, DMSG or EMSG switches clamp onto the stainless barrel for position feedback without any special-order piston.
