The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X600SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 600mm 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.
The CM round-end back cover gives the MAC63X600SCM a clean boss for eye or centre-pivot fixings while the 63 mm bore drives 1558 N at 0.5 MPa (22-145 psi supply). It is double acting, cushioned variably at both ends, and runs 30-800 mm/s - so a 600 mm heavy slide can arrive softly instead of banging the covers.
Its rolled stainless barrel and 20 um hard-chrome rod take coolant splash, humidity and the odd hose-down in stride, an edge painted mini cylinders give up quickly. For sizing, expect about 935 N of push that does real work at 0.5 MPa, roughly a 79 kg vertical lift at half the theoretical margin. The magnet is part of the standard build, letting CMSG / DMSG / EMSG switches clip onto the barrel with no special piston.

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.

|---|---|---|
| 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.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Pivot-raising a 75 kg hatch above a mixing vessel on an eye pin through the CM round-end boss. Half the rated force still lifts about 79 kg, so the hatch moves with margin to spare.
Extending a drip tray under a CNC machining centre during cutting and retracting it for chip clearing. The stainless barrel tolerates coolant splash that swells painted minis.
Swinging a heavy oven-door linkage through its arc on a rack oven line; 1457 N of pull at 0.5 MPa closes the door against gasket drag while the cushion damps the latch.
Compare the 50 mm bore at 981 N (0.5 MPa) for lighter lids; keep this 63 mm bore when a 600 mm slide carries real mass. The stroke runs past the 500 mm standard limit, so it is a made-to-order build. The round-end cover accepts a pivot pin without adapters, while FA flange, LB foot or SDB options anchor the barrel; a 1/4" port feeds each side and the rod thread is M14x1.5. With air off the rod simply drifts under load - add a check valve or rod lock where position matters.
Quick checklist
Rated 1557.9 N push / 1457.4 N pull at 0.5 MPa, climbing to 2181.0 N / 2040.3 N at 0.7 MPa, with a 317.7 kgf theoretical peak at 1.0 MPa. The variable air cushion at both ends lets you run these forces at up to 800 mm/s without hammering the covers.
No. As a double-acting cylinder with no lock, the rod moves wherever the load and gravity take it once supply pressure is gone; the air cushion only slows motion near the ends. For hanging loads fit a rod-lock unit or pilot-operated check valves so the 600 mm stroke stays where you left it.
