Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 100mm 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 MACJ50X100-40S
When the extend position has to land anywhere within a 40 mm band, order this adjustable MACJ and set it on site. The 50 mm bore pushes 981.3 N and pulls 880.8 N at 0.5 MPa, backed by a 1.5 MPa (215 psi) proof pressure. Its stainless round barrel plus hard-chrome plated rod tolerates washdown better than painted-steel minis.
A stop screw shortens the extend stroke anywhere in the 40 mm window, while the cushions at both ends tune the deceleration so the covers last. Expect about 588 N of practical push at 0.5 MPa and roughly 50 kg of vertical lift with a 2:1 margin. CMSG, DMSG and EMSG sensors mount directly thanks to the standard magnet.

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 MACJ50X100-40S Is Used
Machine-tending blank lift
Lifts machined blanks of about 50 kg between spindle and outfeed tray at 0.5 MPa, with the 40 mm window matched to tray height.
Stamping feed stop
Stops strip feed at the exact pitch in a small press feed; cushions settle the stop so the die registers the same every hit.
Bagging machine pusher
Pushes filled bags onto the sealing station of a bagging line, cycling fast on a cushioned stroke with an EMSG switch confirming home.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-40S the Right Cylinder?
Between the 40 mm bore (628.3 N push at 0.5 MPa) and the 63 mm bore (1557.9 N), this 50 mm MACJ at 981.3 N covers mid-range clamping and light pressing. Mount via FA flange or LB foot; the built-in magnet means position feedback needs no special-order piston. Keep side loads off the 16 mm rod where tooling overhangs the 100 mm stroke - guide the load externally instead. The trim screw sets the extend position only and never acts as a load-holding brake.
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 MACJ50X100-40S FAQ
At 0.5 MPa: 981.3 N push, 880.8 N pull. At 0.7 MPa: 1373.8 N push, 1233.1 N pull. Theoretical maximum at 1.0 MPa is 200.1 kgf. Supply air between 0.15-1.0 MPa (22-145 psi) and cycle anywhere in the 30-800 mm/s band.
No. The magnet is built into the piston as standard on every MA-series cylinder, so CMSG, DMSG or EMSG switches clip onto the stainless barrel at any time - even retrofitted years later - without a special piston or factory rework.
