Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 175mm 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 MAC63X175SCM
Dia 63 sits at the top of the MAC bore range: at 0.5 MPa this 175 mm stroke unit pushes 1557.9 N and retracts under 1457.4 N, driven by air on both faces of the piston. Supply anywhere from 0.15-1.0 MPa (22-145 psi) and run the rod at 30-800 mm/s.
The riveted stainless barrel shrugs off washdown that eats painted mini cylinders, and a variable air cushion at each end lets you tune out end-of-stroke shock instead of hammering the covers. The CM round-end cover takes a clevis or yoke knuckle directly, and because the magnet is built in as standard, CMSG, DMSG or EMSG switches clip straight on. For real work, budget roughly 935 N at 0.5 MPa - that is 60 percent of the rating - rather than the full 1557.9 N.

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 MAC63X175SCM Is Used
Press blank transfer lift
Raises 70 kg steel stamping blanks from a decoiler pallet into the press tool over the 175 mm stroke; the 2:1 lift margin of about 79 kg keeps the vertical move comfortable.
Machining fixture clamp
A side-mounted MAC63X175SCM squeezes aluminum gearbox castings into a 4-axis fixture, delivering roughly 935 N of practical clamp force at 0.5 MPa.
Palletizing case ejector
Pushes shrink-wrapped carton stacks sideways off the palletizing conveyor onto a transfer car; the CM round-end cover takes a yoke knuckle for the swinging push.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X175SCM the Right Cylinder?
Step down to the 50 mm bore (981.3 N push at 0.5 MPa) if your load is under about 590 N of actual work; nothing in the MAC line out-pushes the 63. Remember this cylinder drifts if the valve centres or air drops - it is not a holding device - so add a rod lock or pilot check valve for a suspended load. The CM round-end cover pairs with I or Y rod knuckles, and FA flange, LB foot or SDB pivot brackets bolt on when a fixed mount suits the frame better. At 175 mm stroke, keep side load off the 16 mm rod and guide the workpiece externally.
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 MAC63X175SCM FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N. At 0.7 MPa push rises to 2181.0 N and pull to 2040.3 N, and the theoretical maximum for the Dia 63 bore is 317.7 kgf at 1.0 MPa. Ports are 1/4", the rod thread is M14x1.5, and 175 mm is a standard stroke for this bore.
The MAC63X175SCM has a variable air cushion at each end, not fixed bumpers. Back both needle screws off before the first strokes, run the cylinder at low speed, then close them gradually until the 175 mm stroke lands smoothly across the 30-800 mm/s working range. The magnet is already fitted, so CMSG, DMSG or EMSG switches can be added at any time.
