Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-75S 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 MACJ50X100-75S
Wide trim latitude is the point of this model: a 75 mm adjust window on a 100 mm base stroke means one cylinder can be re-set for several product heights without swapping parts. The 50 mm bore is double-acting with a variable air cushion at each end, pushing 981.3 N and pulling 880.8 N at 0.5 MPa, and 1373.8 N at 0.7 MPa.
Underneath, the barrel is stainless steel with a 20 um hard-chrome plated rod and rolled aluminium covers - a build that takes damp washdown corners in stride. On vertical duty the piston lifts about 100 kg at 0.5 MPa; halve that for a 2:1 margin and 50 kg parts sit comfortably in budget. Every unit ships with the magnet already fitted, so a DMSG or EMSG sensor drops on with one screw. Supply runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MACJ50X100-75S Is Used
Mold ejector set-up
Sets ejector travel on an injection tool during tryout; the 75 mm window covers the difference between pre-production and final plates.
Multi-SKU carton pusher
One stroke setting per carton size on a sorter lane; change over between SKUs with a spanner instead of swapping cylinders.
Lab press platen
Drives a small test platen, with the air cushion keeping 1373 N impacts at 0.7 MPa away from the load cell at cycle end.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X100-75S the Right Cylinder?
For lighter clamps, a 40 mm MACJ makes 628.3 N at 0.5 MPa; for heavier tooling, the 63 mm bore reaches 1557.9 N. Treat the 75 mm window as an extend-length setting only - it will not lock the rod against a falling load when pressure fails. FA flange or LB foot mounting, I or Y knuckles on swing links, and a 1/4" air port complete the picture. If the trim never needs changing after commissioning, the fixed-stroke MAC in the same bore is the simpler sibling.
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 MACJ50X100-75S FAQ
Push at 0.5 MPa is 981.3 N, pull 880.8 N. Raise supply to 0.7 MPa and push reaches 1373.8 N. The theoretical maximum output at 1.0 MPa is 200.1 kgf. The rod is 16 mm with an M14x1.5 male thread, and the port is 1/4".
Both are standard. The piston magnet works with AirTAC CMSG, DMSG and EMSG switches for end-position signalling, and the variable air cushion at each end can be throttled to soften stops across the 30-800 mm/s speed range.
