Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X110-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X110-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 110mm 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 MACJ50X110-20S
Fine positioning rather than coarse: the 20 mm trim window on this 110 mm stroke lets maintenance dial the extend length in millimetre steps for registration-critical tooling. Output from the 50 mm bore is 981.3 N forward and 880.8 N back at 0.5 MPa, rising to 1373.8 N at 0.7 MPa, double-acting with a variable air cushion closing each end.
The riveted stainless barrel and hard-chrome rod make it a natural for humid plants where a painted mini would bubble and seize. Plan real pushing work at roughly 589 N at 0.5 MPa rather than the full rating, and the two-way piston seal with its grease store keeps cycles smooth for years. Speed spans 30-800 mm/s across 0.15-1.0 MPa (22-145 psi), and the standard magnet accepts CMSG, DMSG or EMSG switches.

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 MACJ50X110-20S Is Used
Registration stop on a print feeder
Nudges sheet registration a few millimetres per job; the 20 mm window matches the adjustment range of the side-lay.
Die kicker
Ejects slugs from a stamping die between hits; 981 N of push clears even oiled scrap out of the nest.
Bottling line gate
Stops bottles ahead of the filler, the cushion bringing the gate to rest without rattling the guide rail.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X110-20S the Right Cylinder?
Sizing check: 32 mm gives 402.2 N at 0.5 MPa and 63 mm gives 1557.9 N, so this 50 mm class suits mid-weight links and clamps between those. If the trim will never change after commissioning, the fixed-stroke MAC in the same bore is worth a look; for tooling loaded on both rod sides, the double-rod MACD is the variant. The 20 mm stop sets position only and cannot hold a load against gravity without air. FA and LB mounts, I and Y knuckles, 1/4" port.
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 MACJ50X110-20S FAQ
For the 50 mm bore: push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. Supply pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speed runs 30-800 mm/s.
The riveted stainless tube seals as one rolled unit with no external fasteners to loosen, and the 20 um hard-chrome rod resists the washdown chemicals that pit painted rods. It is a compact round mini format rather than a profile extrusion, so it slots into tight machine frames.
