Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCMLB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MAC32X80SCMLB
Foot-mounted and ready to bolt to a machine base, this 32 mm MAC carries an LB bracket under a rolled stainless body. Double-acting with a variable cushion at each end, it drives 402 N forward and returns 345.6 N at 0.5 MPa, rising to 563 N at 0.7 MPa across the 80 mm stroke.
Foot mounting spreads the thrust into the frame, handy where a face mount cannot take the reaction. The hard-chrome 12 mm rod and stainless tube stand up to coolant splash and washdown, and the standard magnet accepts CMSG, DMSG or EMSG switches for end-of-stroke signalling. For real-world sizing, count on roughly 241 N of usable push at 0.5 MPa - about a 20 kg vertical lift with a 2:1 safety margin.

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 MAC32X80SCMLB Is Used
Load pusher at a pallet-stacking station
Slides stacked cartons onto a staging conveyor from beneath the frame line; the LB feet carry the 402 N reaction down into the base weldment.
Web tension dancer on a film rewinder
An LB-mounted cylinder biases the dancer roller to hold web tension constant; the cushion smooths tension spikes at every splice.
Cable-drum brake actuator in a wire shop
Presses a friction shoe against a drum flange to slow payoff; the oil mist in the shop does not bother the stainless barrel.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCMLB the Right Cylinder?
LB feet let the barrel sit below or beside the load line, unlike the face-fixed U cover or the swinging CA tail; SDB pivot brackets are the third option if the mount must articulate. Lighter duty drops to a 25 mm bore at 245 N (0.5 MPa), heavier duty climbs to a 40 mm bore at 628 N. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure. If the load must hold when the valve centres, fit a rod lock - the MAC itself will drift.
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 MAC32X80SCMLB FAQ
Extension force is 402.2 N and retraction 345.6 N at 0.5 MPa. Step up to 0.7 MPa for 563.0 N push and 483.8 N pull; 82 kgf is the theoretical top at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi), and the 12 mm rod carries an M10x1.25 thread.
LB feet let the barrel sit under a platform or beside a guide, taking thrust into the machine base instead of a cover face. If the mount must articulate, the SDB bracket or a CA back cover suits better. All versions share the same stainless barrel and hard-chrome rod, so washdown duty is unaffected either way.
