Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 200mm 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 MACJ50X200-40S
With a 40 mm trim window on its 200 mm extend stroke, this 50 mm bore MACJ gives technicians wide on-site latitude without changing the cylinder. Push force is 981.3 N at 0.5 MPa (1373.8 N at 0.7 MPa), and the riveted stainless barrel with hard-chrome plated rod resists corrosion in wet or outdoor spots where painted minis fail.
Both ends carry a variable air cushion, so heavier or faster loads stop without battering the aluminium covers. Every MA-series unit ships with the magnet already fitted, so CMSG, DMSG and EMSG switches drop on with no special-order piston. For lifting, 981.3 N corresponds to about 100 kgf, so plan on roughly 50 kg vertical lift to keep a 2:1 margin.

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 MACJ50X200-40S Is Used
Clamp fixture on a CNC fixture plate
Swing clamps and push clamps on machining fixtures get repeatable clamping; the 40 mm window absorbs fixture-to-fixture variation across a 200 mm approach.
Palletizer pusher arm
A pusher that squares cartons on a pallet gains 981 N of thrust at 0.5 MPa, trimming the final push distance within the 40 mm band.
Bottle fill-height stop
On a bottling line, the adjustable stop sets fill-head depth so each bottle fills identically; cushions stop the head from slamming at speed.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-40S the Right Cylinder?
Compare against neighbours: the 40 mm bore manages 628.3 N at 0.5 MPa and the 63 mm bore reaches 1557.9 N, so this 50 mm size covers the middle ground. Remember the adjuster only shortens extension and holds nothing if air drops - position retention needs a separate valve solution. FA flange or LB foot mounting, plus I or Y knuckles, and a 1/4" port keep plumbing simple.
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 MACJ50X200-40S FAQ
Push at 0.5 MPa is 981.3 N and pull 880.8 N; at 0.7 MPa you get 1373.8 N push and 1233.1 N pull. Maximum theoretical force at 1.0 MPa is 200.1 kgf. The cylinder runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof, and cycles at 30-800 mm/s.
The rolled stainless tube and 20 um hard-chrome rod handle washdown, humidity and mild outdoor exposure better than painted steel minis. The rod is 16 mm dia with a M14x1.25 male thread, and a variable air cushion at each end protects the covers at high speed.
