Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCM 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 MAC32X80SCM
The CM round-end back cover on this 32 mm MAC gives a clean, compact tail for tight frames, while air on both sides of the piston makes it double acting. Expect 402 N forward and 345.6 N return at 0.5 MPa, or 563 N forward at 0.7 MPa, with a variable cushion at each end of the 80 mm travel.
Inside is a riveted stainless tube with a hard-chromed 12 mm rod - construction that shrugs off splash, humidity and periodic hose-down where aluminium minis pit. The magnet is fitted as standard, so position feedback with CMSG, DMSG or EMSG switches needs no special-order piston. As a working figure, budget near 241 N at 0.5 MPa for real work; that is the same as holding about 20 kg vertically with a 2:1 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 MAC32X80SCM Is Used
Clamping fixture on a CNC tombstone
Holds aluminium blanks against a tombstone during milling; around 241 N of dependable push keeps thin parts seated without crushing them.
Case closer on a soap-wrapping machine
Folds the final flap on detergent cartons; the cushion stops the flap press hard against the forming plate even at high line speeds.
Reagent tray indexer in a lab washer
Steps trays through a wash chamber; stainless construction tolerates the steam and detergent mist that swells painted housings.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X80SCM the Right Cylinder?
Round-end CM tails suit direct-mounted duties where a clevis-style tail would add length; when the machine wants a pivoting tail instead, the CA cover version is the closer match, and LB foot or FA flange brackets bolt on either way. Step down to a 25 mm bore (245 N at 0.5 MPa) for lighter clamps or up to 40 mm (628 N) for heavier tooling. Remember this cylinder cannot park a load on lost air - a rod lock or check valve does that job.
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 MAC32X80SCM FAQ
At 0.5 MPa: 402.2 N extend, 345.6 N retract. At 0.7 MPa: 563.0 N extend, 483.8 N retract. The ceiling is 82 kgf at 1.0 MPa theoretical. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, with 1/8" ports.
Back both cushion needle screws fully out before start-up, then close them gradually until end-of-stroke knock disappears. The cushion is variable, not fixed, so you can retune it as speed or load changes anywhere in the 30-800 mm/s range. Never treat it as a brake - with air off, the piston drifts freely.
