Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 85mm 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.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCA
Pivot mounting comes built in on the MAC32X85SCA: the CA back cover carries an integral pivot eye, so linkage arms connect without an extra bracket. Output at this 32 mm bore is 402 N extend and 346 N retract at 0.5 MPa, climbing to 563 N and 484 N at 0.7 MPa with an 82 kgf theoretical peak. The cylinder is double acting - air drives the rod out and back - and a variable air cushion at each end takes the sting out of the stop across a 30-800 mm/s speed span.
Build quality suits hostile corners of the plant: a stainless round barrel rolled onto aluminium covers, with a hard-chrome plated rod that rides out washdown and humid air. Every piston ships with its magnet already fitted, so CMSG, DMSG and EMSG switches drop straight on. For sizing, figure on 241 N of honest output at 0.5 MPa - about 20 kg of vertical lift once a 2:1 margin is applied - across the 85 mm stroke.

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 (Ø32mm)
| 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.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCA Is Used
Pallet conveyor swing stop
The CA pivot eye hangs the cylinder on a linkage that swings a stop plate into the pallet lane between transfers.
Sortation chute gate
Opens and closes a gravity chute gate in a small-parts sortation loft, with 346 N of retract force swinging it shut under air.
Nozzle arm oscillator
Sweeps a rinse nozzle arm across a tray-washer tunnel, the stainless barrel riding out constant splash.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCA the Right Cylinder?
Compare against the 25 mm bore, which gives 245 N at 0.5 MPa, or the 40 mm bore at 628 N if the load grows. A cushioned cylinder is not a holding device: with air off or the valve neutral the rod drifts, so add a pilot check valve or rod lock for suspended loads. SDB pivot brackets, FA flanges and LB feet all bolt to this series, and the 1/8" ports sit on the back cover. Over 85 mm of travel, guide the load externally rather than letting the 12 mm rod carry side force.
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 MAC32X85SCA FAQ
The 32 mm bore yields 402 N extend and 346 N retract at 0.5 MPa, rising to 563 N and 484 N at 0.7 MPa, with 82 kgf as the 1.0 MPa theoretical ceiling. Fluid is 40 um filtered air, speed runs 30-800 mm/s, proof pressure is 1.5 MPa (215 psi) and the working range is 0.15-1.0 MPa (22-145 psi).
It adds an integral pivot eye at the rear, so rod linkages, swing arms and SDB pivot brackets connect without adapter plates. Everything else is unchanged: stainless round barrel, hard-chrome rod, standard piston magnet for CMSG / DMSG / EMSG switches, and an 85 mm stroke well inside the 500 mm standard range.
