Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 125mm 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 MAC63X125SCM
Sitting at the top of the MA range, the MAC63X125SCM turns 0.7 MPa shop air into 2181 N of push - the strongest output the 16-63 mm round-body series offers. Double acting throughout, with needle-adjustable air cushions at each end taming 125 mm of travel; a riveted stainless tube and 20 um chrome-plated rod keep corrosion out of humid or wash-prone cells.
Derate sensibly: at 0.5 MPa keep actual work near 935 N of the 1558 N push, which still swings a 79 kg vertical lift once the 159 kg theoretical figure is halved for a 2:1 margin. The CM round-end back cover bolts to fixed frames without an extra bracket, and the piston magnet comes standard for CMSG, DMSG and EMSG position switches.

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 MAC63X125SCM Is Used
Cast part marking press
A foundry bench stamping batch codes into aluminium housings needs over 900 N per hit - inside the 935 N working force at 0.5 MPa with the cushion catching each strike.
Heavy tote gate ram
Sliding 300 kg flow-rack gate assemblies draws around 600 N, leaving ample headroom on the 1558 N push available at 0.5 MPa.
Drum clamp actuator
Closing a drum-clamp linkage on a palletising cell; the CM round end seats flat against the clamp frame with no adapter plate.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCM the Right Cylinder?
The 50 mm bore below delivers 981 N at 0.5 MPa; this 63 mm barrel tops the series at 1558 N push, and nothing larger exists in the family. A failing supply leaves the load unsupported - fit a rod lock or pilot check valve where a press or clamp must stay put. Mounting choices run from FA flange and LB foot to SDB pivot, with I and Y knuckles for rod ends, and the CM round-end cover seats flat on bracketed frames. Air supply 0.15-1.0 MPa (22-145 psi); 1/4" ports; PT thread standard, G and NPT order options.
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 MAC63X125SCM FAQ
At 0.5 MPa: 1558 N push and 1457 N pull. At 0.7 MPa: 2181 N push and 2040 N pull. Theoretical maximum is 318 kgf at 1.0 MPa. The rod is 16 mm with M14x1.5 male thread, ports are 1/4", and the stroke is 125 mm.
The CM round-end cover presents a clean fixed mounting face for bracketed frames, while the piston magnet - included as standard, not a paid option - drives CMSG, DMSG or EMSG switches mounted along the barrel for position signalling.
