Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X250-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X250-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 250mm 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 MACJ63X250-10S
The MACJ63X250-10S puts AirTAC's largest MA bore to work: 1557.9 N of push and 1457.4 N of pull at 0.5 MPa, climbing to 2181.0 N at 0.7 MPa with a theoretical ceiling of 317.7 kgf. It is double-acting with a variable air cushion at both ends, and an external stop screw trims the extend stroke anywhere within a 10 mm window - shorter than the ordered 250 mm, never longer.
The stainless round barrel and hard-chrome plated rod (20 um) shrug off washdown and damp shop air far better than painted-steel minis, while the magnet built into every piston means CMSG, DMSG or EMSG switches clip on without a special order. At 0.5 MPa, plan on roughly 935 N of push for real work - enough to lift about 79 kg vertically with a 2:1 margin - running on 0.15-1.0 MPa (22-145 psi) filtered air 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 (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 MACJ63X250-10S Is Used
Pallet nailing jig
Seats pallets into a nailing station with 1558 N of cushioned push; the 10 mm trim window absorbs tooling height changes without re-plumbing.
Carton case clamp
Closes a heavy-duty case clamp across a 250 mm stroke; variable cushions stop the clamp from slamming even at 0.7 MPa line pressure.
Tote diverter gate
Pushes totes between conveyor lanes; a CMSG switch on the standard built-in magnet confirms full retract between cycles.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X250-10S the Right Cylinder?
Stepping down to the 50 mm bore of the same series saves air but drops push to 981.3 N at 0.5 MPa against this cylinder's 1557.9 N - and 63 mm is the ceiling of the MA range, so bigger jobs mean a different series. Over a 250 mm stroke, misalignment compounds; keep side loads on machine guides, not on the 16 mm chrome rod. Mount with an FA flange or LB foot and add I or Y rod knuckles where the load pivots. The stop screw trims the extend stroke only - it is not a load lock, and the rod will drift if air is lost.
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 MACJ63X250-10S FAQ
At 0.5 MPa the bore produces 1557.9 N push and 1457.4 N pull; at 0.7 MPa that rises to 2181.0 N and 2040.3 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. The external stop screw trims the extend stroke anywhere within a 10 mm window, and variable air cushions at both ends stay active across the full range.
The barrel is stainless steel and the 16 mm rod is carbon steel hard-chrome plated to 20 um, riveted into aluminium-alloy covers for a sealed round body - a genuine edge in damp, washdown or outdoor spots over painted minis. The position magnet is built in as standard, so CMSG, DMSG or EMSG switches mount without any special-order piston.
