Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 470mm 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 MAC32X470SCA
With a 12 mm hard-chrome rod inside a riveted stainless round barrel, the MAC32X470SCA swings a 470 mm stroke and pushes 402.2 N at 0.5 MPa (pull 345.6 N). The CA pivot back cover lets the cylinder articulate with the load, so no extra clevis bracket is needed on swinging or tilting linkages.
The double-acting design breathes air both ways and carries a variable air cushion at each end - back the needle screws off on start-up, then close them gradually to tame end-of-stroke shock. At 0.7 MPa the push climbs to 563.0 N. Budget roughly 241 N of real working force at 0.5 MPa and this unit will lift about 20 kg vertically with margin; the standard magnet accepts CMSG, DMSG or EMSG switches without a special-order 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.
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 MAC32X470SCA Is Used
Swing-link die lifter
The CA pivot follows the arc of a hinged die cart lifted at the edge of a stamping press, where a fixed-mount cylinder would side-load its 12 mm rod.
Cross-transfer pusher
Moves 8 kg carton stacks sideways between two conveyor lanes; 402 N of push at 0.5 MPa clears the gap in under a second at 500 mm/s.
Paint-line gate actuator
The stainless barrel and chrome rod shrug off paint-shop humidity while the 470 mm stroke swings a wash-booth sliding gate fully open.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X470SCA the Right Cylinder?
Compare forces at 0.5 MPa push: the 25 mm bore gives 245.3 N, this 32 mm bore 402.2 N, and the 40 mm bore 628.3 N - step up if your load sits above roughly 240 N of continuous work. Because MAC is double acting, a de-energised valve lets the rod drift; fit a pilot check valve or rod lock if the load must stay put on air loss.
The CA pivot back cover pairs naturally with the SDB pivot bracket or I/Y rod knuckles, and 1/8" ports keep plumbing simple. On a 470 mm stroke, guide the load so side forces stay off the 12 mm rod, or add external guidance for long travels.
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 MAC32X470SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push rises to 563.0 N and pull to 483.8 N. The theoretical ceiling is 82 kgf at 1.0 MPa. Air supply must stay within 0.15-1.0 MPa (22-145 psi) and be filtered to 40 um.
Run the needle screws fully open for the first cycles, then close them a turn at a time until the 470 mm stroke decelerates smoothly at both ends. Speed range is 30-800 mm/s; if the piston hammers the covers, open the needles further rather than slowing the valve.
