Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 175mm 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 MACJ63X175-75S
The widest on-site trim in this force class: -75 means the extend stroke of this 63 mm MACJ can be shortened by up to 75 mm after install, one cylinder covering a family of stations. Double-acting with a variable air cushion at both ends, it delivers 1558 N at 0.5 MPa and cycles from 30 to 800 mm/s.
The stainless round barrel and hard-chrome 16 mm rod hold up in wet, dusty and outdoor corners where painted minis fail, and the magnet built in as standard lets CMSG, DMSG or EMSG switches report position with no special order. In real work, plan on about 935 N at 0.5 MPa -- around 79 kg lifted vertically at 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 (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 MACJ63X175-75S Is Used
Baler eject plate
Drives the eject plate on a small waste baler; 1558 N at 0.5 MPa clears compacted material cycle after cycle.
Lift-assist riser
Raises a fixture column on an assembly rail; with about 935 N of working push the station comfortably handles 79 kg-class parts.
Industrial oven door
Swings a heavy oven door on a heat-treatment line; the 75 mm trim compensates for hinge wear, and the cushion eases the close.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-75S the Right Cylinder?
A 50 mm MACJ (981 N at 0.5 MPa) is the smaller sibling; nothing in the series offers more bore than these 63 mm. The -75 stop only shortens the extend stroke and never lengthens it past 175 mm, and it is an end stop rather than a mid-stroke lock, so a drifting piston on air loss is still possible -- fit a holding valve where that matters. Choose FA flange or LB foot for the body, I or Y knuckle for the rod end, and support long or side-loaded jobs with external guides to spare the 16 mm rod.
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 MACJ63X175-75S FAQ
Push at 0.5 MPa is 1558 N, pull 1457 N; at 0.7 MPa push reaches 2181 N and pull 2040 N; theoretical maximum at 1.0 MPa is 317.7 kgf. It runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure, and operates -20 to +70 C at 30-800 mm/s.
Both ends carry a variable cushion: close the needle slightly for heavy loads or fast travel, open it for light, slow cycles, so the 175 mm stroke ends softly without hammering the aluminium covers. Remember the -75 adjuster sets the extend stop mechanically and does not hold the load if air is lost.
