Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 225mm 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 MAC Stainless Steel Mini Air Cylinder MAC63X225SCA
At 225 mm of stroke this 63 mm cushioned mini cylinder reaches deep into chutes, doors and diverter arms while still delivering 1557.9 N at 0.5 MPa (2181.0 N at 0.7 MPa). Air works both directions - it is fully double acting - and the adjustable air cushion at each end absorbs end-of-stroke shock so you can push faster or move heavier gates without hammering. Stainless barrel, hard-chrome rod, riveted aluminium covers: built for damp and outdoor corners.
The built-in magnet pairs with CMSG, DMSG or EMSG reed switches out of the box. Derate to about 935 N for real work at 0.5 MPa, which matches a vertical pull of around 79 kg on a counterweighted door or lever. Ports are 1/4" and the male rod thread is M14x1.5.

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 MAC Stainless Steel Mini Air Cylinder MAC63X225SCA Is Used
Flour-sack lane diverter in a mill
Pushes heavy sacks across the lane at 1557.9 N, 0.5 MPa, while the adjustable cushion settles each stroke without jolt.
Mixing-drum tilt on a refractory mixer
The pivot back cover follows the tilt arc through the full 225 mm stroke, and the stainless barrel handles the dusty, damp mix room.
Scrap gate under a CNC machining line
Opens a heavy chip gate at up to 800 mm/s; coolant splash is a non-issue for the riveted stainless barrel and chromed rod.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCA the Right Cylinder?
Compare the 50 mm bore first: its 981.3 N push at 0.5 MPa covers lighter diverter duties and saves air. When the math shows you need more, this 63 mm model is the ceiling of the family. A 225 mm rod is a long unsupported column - mount the load on its own guides and keep thrust axial, especially near 800 mm/s. The CA pivot ears let the body swing on a pin through the stroke; choose the CM round cover or U flat end for rigid mounts. For any position that must hold without air, a rod lock or pilot check valve is required - the cushion damps impact, it never locks the 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 MAC Stainless Steel Mini Air Cylinder MAC63X225SCA FAQ
Push is 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa expect 2181.0 N push and 2040.3 N pull; theoretical maximum is 317.7 kgf at 1.0 MPa. The 225 mm stroke sits within the 500 mm standard range, and operating pressure is 0.15-1.0 MPa (22-145 psi).
No. A double-acting MAC cylinder with both sides vented lets the piston drift, so an unpowered gate will sag under gravity. Fit a pilot check valve or a rod-lock version where the load must stay parked; the air cushion only softens the final approach, it is not a lock.
