The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X200SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 200mm stroke, 1/8" 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.
Round covers, riveted joints and a stainless tube give the MAC32X200SCM a body that laughs at splash, humidity and light washdown in damp plant corners. Its 32 mm bore turns 0.5 MPa into 402 N of push and 0.7 MPa into 563 N, ample for mid-size press, eject or transfer heads. Air drives the piston both ways - double acting - and a variable cushion at each end absorbs stroke-end bang; open the needle screws before the first run, then close them gradually.
Sensing needs no special order: the magnet is standard equipment and CMSG / DMSG / EMSG switches mount straight onto the barrel. For planning, hold a 40 percent reserve and the bore gives about 241 N of continuous working force at 0.5 MPa - tool loads under that figure keep the 200 mm stroke smooth across 30-800 mm/s. The CM round-end cover presents a clean face for fixture bolts or a knuckle.

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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| 32 | Bore size in mm. |
| ×200 | Stroke length in mm. |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
A 402 N push at 0.5 MPa kicks five-kilogram cartons across a diverter lane; at 30-800 mm/s the stroke timing can be matched to the belt pitch.
Retract force of 346 N at 0.5 MPa holds pouches flat against the filling nest; the CM round-end cover bolts flat inside the machine guard.
The variable air cushion stops the glue head from slamming the flap at stroke end, so nozzle position stays true shift after shift.
Step down to a MAC25 for lighter duty - 245 N push and 206 N pull at 0.5 MPa - or up to a MAC40 for 628 N push and 528 N pull. Do not treat the cushion as a brake: with the air off the piston coasts and the load drifts, so fit a rod lock or pilot check valve where positions must hold. The CM round-end cover plus FA flange, LB foot or SDB pivot brackets covers most fixture patterns, and every unit ships with its magnet built in for CMSG / DMSG / EMSG sensing. Support side loads externally over the 200 mm stroke to keep the 12 mm rod straight.
Quick checklist
Bore 32 mm: 402 N push and 346 N pull at 0.5 MPa, climbing to 563 N push and 484 N pull at 0.7 MPa, with 82 kgf as the theoretical maximum at 1.0 MPa. Fluid is air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), driving the 12 mm rod at 30-800 mm/s through 1/8" ports.
The rolled stainless tube plus hard-chrome plated rod shrug off splash, humidity and light washdown that chew through painted mini cylinders, while the CM round-end cover gives a flat face for fixture bolts or a knuckle joint. Grease held in the two-way piston seal keeps the bore lubricated between services.
