Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X60-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X60-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MACJ40X60-30S
Machine builders pick the MACJ40X60-30S when the exact stopping point is only known after commissioning: the stop screw trims the extend stroke anywhere inside the 30 mm window, while retraction stays full length. Double-acting with variable air cushioning at each end, it carries a 16 mm hard-chrome rod on a stainless round barrel. The 0.5 MPa push figure is 628 N, which in practice means roughly 377 N of continuous work or about 32 kg lifted vertically with a 2:1 margin.
Fluid is filtered air at 0.15-1.0 MPa (22-145 psi), speeds span 30-800 mm/s, and the built-in magnet is standard equipment, ready for CMSG / DMSG / EMSG switches. Note that the stop positions the stroke but is not a brake - with air off, the piston can still be pushed along its travel.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MACJ40X60-30S Is Used
Stopper gates on assembly pallets
Pulse the MACJ40X60-30S to raise a pallet stopper; the 30 mm window lets commissioning set the exact dwell height, cushioned at both ends.
Press-assist part ejection
After a light forming press, air ejects finished rings with 628 N push at 0.5 MPa; EMSG sensing on the standard magnet confirms full retraction.
Lab fixture positioning
Trim the extend stop to hold sample trays at a repeatable height in a test rig running on clean 40 um filtered air.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X60-30S the Right Cylinder?
Compare bores on real numbers: 32 mm gives 402.2 N push at 0.5 MPa, this 40 mm bore 628.3 N push and 527.8 N pull, and the 50 mm bore 981.3 N. Choose one class up whenever cycle rates are high, so the cylinder works near 60 percent of its rating instead of at the limit.
FA flange and LB foot mountings cover most frames; I and Y knuckles suit pivoting loads. With only 60 mm of stroke, rod bending is not a concern at these force levels, though keep side loads off the rod in any case. Remember the adjuster is a positioning stop, so any load that must stay put on air failure needs a separate locking valve.
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 MACJ40X60-30S FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; theoretical peak 128.1 kgf. The 40 mm bore drives a 16 mm rod through 1/8" ports, works on 0.15-1.0 MPa (22-145 psi), runs 30-800 mm/s, and the extend stroke adjusts within a 30 mm window with dual-end air cushioning.
Yes. Every MA-series cylinder leaves the factory with a piston magnet as standard, so CMSG, DMSG and EMSG switches clip onto the barrel for end-of-stroke detection without ordering a special version.
