Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm 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 MACJ63X100-75S
With three quarters of its 100 mm stroke adjustable, the MACJ63X100-75S gives the widest trim latitude in this bore size. Double-acting and cushioned at both ends, the 63 mm piston pushes 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa, enough for a vertical lift equivalent of about 159 kg on the theoretical rating.
Apply a 2:1 margin and that becomes about 79 kg of real payload per cycle. A stainless barrel rolled onto its covers, plus a hard-chrome rod, keeps corrosion at bay in outdoor gates, marine fixtures and humid plants. Magnet position sensing via CMSG / DMSG / EMSG switches is standard, not a paid option.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X100-75S Is Used
Sluice gate nudger at a waterworks
Strokes a small sluice or penstock linkage outdoors, where the stainless body and chrome rod shrug off constant moisture year round.
Height clamp on a welding fixture
Sets fixture height per car body variant, using the 75 mm window between models on a mixed-model production line.
Keg pusher in a brewery
Moves full kegs onto a filling rail; the 1457.4 N pull at 0.5 MPa retracts the pusher plate under load without stalling.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-75S the Right Cylinder?
Size down to the 50 mm bore and its 981.3 N push at 0.5 MPa when the working load stays under about 589 N; otherwise 63 mm is the top of the MA ladder. The 75 mm window fits jobs where the extend stop is reset often - batch changovers, adjustable gauges, multi-part fixtures. Note the stop is a stroke trim only: it neither lengthens travel past 100 mm nor holds the load against falling air pressure.
Port threads are 1/4" at this bore, rod thread M14x1.5, and mounting runs to FA flange, LB foot or I / Y knuckles. At the fast end of the 30-800 mm/s range with a 100 mm stroke, keep the load guided so the 16 mm rod sees pure thrust.
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 MACJ63X100-75S FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181.0 N push, 2040.3 N pull. Maximum theoretical force is 317.7 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi); proof pressure 1.5 MPa (215 psi); speed 30-800 mm/s; fluid is air filtered to 40 um.
The stop screw sets where the extend stroke ends, anywhere from 25 mm to 100 mm of travel; retract is always the full 100 mm. Because the variable cushion works independently at each end, you can trim the extend stop short and still get a soft, cushioned landing at the new position.
