Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-30S 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 MACJ63X175-30S
Big force in a small round body: this 63 mm MACJ pushes 1558 N at 0.5 MPa, and the external stop screw lets the setter trim extend travel by up to 30 mm on site. Double-acting throughout, it runs at 30-800 mm/s and a variable air cushion at both ends soaks up end-of-travel shock so faster cycles do not hammer the covers.
The stainless barrel and hard-chrome plated 16 mm rod shrug off washdown and damp corners where painted minis corrode, and the magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on with no special-order piston. For sizing, budget about 935 N of real work at 0.5 MPa, which is roughly a 79 kg vertical lift 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 MACJ63X175-30S Is Used
Punch-press part ejection
Kicks formed brackets off a die table between strokes; 1558 N at 0.5 MPa clears the nest even with the plant air sagging.
Clamp fixture on a machining centre
The 30 mm trim window lets the setter dial in clamp travel after a fixturing change, with the both-end cushion killing clamp slam.
Die-cart locate and push
Rolls heavy die carts to a hard stop on the extend stroke; the 1/4" port keeps flow up across the full 30-800 mm/s band.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-30S the Right Cylinder?
A 63 mm bore tops the MA range, so step down to a 50 mm MACJ (981 N push at 0.5 MPa) only when the load clearly allows. The -30 stop is a mechanical end stop for the extend direction: it sets position but does not lock the load, and on air loss the piston can still drift, so add a locking valve where the load must stay put. Mount with an FA flange or LB foot, add an I or Y rod knuckle where the link pivots, and at 175 mm stroke guide the load to keep side bending off 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 MACJ63X175-30S FAQ
At 0.5 MPa it pushes 1558 N and pulls 1457 N; at 0.7 MPa push rises to 2181 N and pull to 2040 N. The theoretical ceiling at 1.0 MPa is 317.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s.
An external stop screw shortens the extend stroke by up to 30 mm from the 175 mm nominal; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. A variable air cushion at both ends then dials out the remaining shock, and the standard-built magnet accepts CMSG / DMSG / EMSG switches.
