Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCM 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 MAC63X225SCM
A CM round-end back cover gives this 225 mm stroke cylinder a clean fixing face for custom brackets and machine frames. Underneath, it is the familiar MAC package: double-acting power with a variable air cushion at both ends, 1557.9 N of push and 1457.4 N of pull at 0.5 MPa, and a riveted stainless-steel barrel with a 20 um hard-chrome rod that tolerates washdown better than painted mini cylinders.
Speeds of 30-800 mm/s let you tune each station, and the standard magnet accepts CMSG, DMSG and EMSG switches without ordering a magnetic piston. For sizing, treat about 935 N as the practical working push at 0.5 MPa - roughly a 79 kg vertical lift with a 2:1 margin built in.

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 MAC63X225SCM Is Used
Hopper slide gate on a pellet silo
Slides a plate gate open against pellet column pressure using 1557.9 N at 0.5 MPa, with the cushion settling the gate onto its stop.
Pallet-ejector blade at a loading dock
Ejects pallets from a stacking magazine; the CM round cover fixes straight to the fabricated pusher bracket without adapters.
Weld-fixture clamp riser
Raises a clamp riser 225 mm for part loading, then drops it back into the jig; an EMSG switch confirms the down position each cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X225SCM the Right Cylinder?
Start by pricing the 50 mm bore at 981.3 N push, 0.5 MPa; if that passes your load check with margin, buy the lighter cylinder. If not, this is the largest bore AirTAC offers in the series. The CM round-end cover presents a machined face for direct bracket work, and FA flange, LB foot or SDB pivots bolt on when the layout calls for them. A 225 mm stroke amplifies side-load: guide the mass externally and align the rod axis, or expect accelerated seal wear. And because this cylinder is double acting with no internal lock, a centred valve or lost supply leaves the load free to sag - a pilot check valve or rod lock solves it.
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 MAC63X225SCM FAQ
At 0.5 MPa: 1557.9 N extend, 1457.4 N retract. At 0.7 MPa: 2181.0 N extend, 2040.3 N retract. The theoretical ceiling is 317.7 kgf at 1.0 MPa. It is double acting, runs 30-800 mm/s, and carries 1/4" ports with an M14x1.5 male rod thread.
The stainless barrel plus 20 um hard-chrome rod resist corrosion in washdown, food and outdoor duty, and the rolling-packed covers keep the joint sealed with no tie rods to retighten. Mounting stays flexible too: CM round-end covers now, FA flange, LB foot or SDB pivot brackets later.
