Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCA 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 MAC63X125SCA
A 125 mm stroke gives this 63 mm bore MAC cylinder reach as well as force: 1558 N extend and 1457 N retract at 0.5 MPa, 2181 N extend at 0.7 MPa, and a 317.7 kgf theoretical maximum. Air works both ways on this double-acting unit, and the variable cushion at each end protects the covers when you push the speed toward 800 mm/s.
The barrel is stainless steel rolled over aluminium-alloy covers with a stainless-steel block, and the carbon-steel rod is hard-chrome plated to 20 um - a build that shrugs off coolant splash better than painted minis. Position feedback comes free: the magnet ships inside every piston for CMSG, DMSG or EMSG switches. Practically, expect about 935 N of dependable working push, around 95 kg, leaving headroom for friction, seal drag and linkage losses.

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 MAC63X125SCA Is Used
Water-skid gate actuator
Sluice gate actuation on a small water-treatment skid - the stainless barrel handles the wet environment while 1558 N drives the gate.
Swing strap clamp
Long-travel clamp on a machining fixture, swinging a strap clamp 125 mm clear so the operator can load the part unhindered.
Mould-change pusher
Mould-change pusher in a plastics shop, sliding a heavy clamp plate the full 125 mm on a single 0.5 MPa supply line.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SCA the Right Cylinder?
Downsize to the 50 mm bore, worth 981 N at 0.5 MPa, if the load is light; this 63 mm bore is the strongest standard MAC before moving up to larger industrial frames. At 125 mm of stroke, watch rod alignment - side thrust bends the 16 mm rod, so guide long pushers externally or use a Y knuckle at the pivot. The CA back cover pins directly into levers and gates, and FA flange, LB foot or SDB pivot brackets adapt it to fixed frames. The piston is free to move when supply air is cut, so a pilot check valve or rod lock is the fix for must-hold positions.
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 MAC63X125SCA FAQ
Use 1558 N push and 1457 N pull at 0.5 MPa, or 2181 N push and 2040 N pull at 0.7 MPa; theoretical peak is 317.7 kgf. It is double acting with a variable cushion at both ends, fed through 1/4" ports, with an M14x1.5 rod thread and 0.15-1.0 MPa (22-145 psi) pressure range.
The round barrel is stainless steel riveted to aluminium-alloy covers, and the carbon-steel rod carries a 20 um hard-chrome plating - a combination that handles washdown, coolant mist and outdoor dust far better than painted-steel mini cylinders.
