Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MAC32X400SCA
Air working both sides of the piston makes the MAC32X400SCA fully double acting, and its adjustable cushion at each end lets you trim the last millimetres of a 400 mm travel. At 0.5 MPa the 32 mm bore develops 402.2 N of push, and the stainless rolled barrel with a 20 um hard-chrome rod handles damp shop air that corrodes painted minis.
Divide 402.2 N by gravity and you get a 41 kg force equivalent; keep vertical lifts near 20 kg of that and the cylinder holds a comfortable 2:1 margin. The CA pivot back cover swings freely on linkages, and since the magnet ships as standard, CMSG / DMSG / EMSG switches mount directly onto the barrel.

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 MAC32X400SCA Is Used
Hopper gate tilt
Tilts the discharge gate of a small ingredient hopper through a pivot linkage; the CA cover swings freely and 402 N of push at 0.5 MPa shears sticky product loose.
Pallet swing-stop
Swings a stop arm across a pallet conveyor lane to stage loads; the dual-end cushion keeps the arm from slamming over its 400 mm travel.
Booth damper linkage
Drives the damper linkage on a spray-booth exhaust, where washdown-tolerant stainless construction and the standard magnet for CMSG switches suit intermittent damp duty.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCA the Right Cylinder?
Downsize to a 25 mm bore (245.3 N at 0.5 MPa) for light gates, or up to 40 mm (628.3 N) for stiffer loads. Remember the rod is free to move once supply pressure drops or the valve sits mid-position - a pilot check valve or rod lock is the fix when position must be held. The CA pivot suits swinging linkages; pair LB foot or FA flange hardware with it when the body itself needs fixing, and support the 400 mm stroke against side load with external guides.
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 MAC32X400SCA FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa expect 563.0 N push and 483.8 N pull, peaking at a theoretical 82 kgf at 1.0 MPa. The pressure band is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports 1/8" in PT, G or NPT.
Back both cushion needle screws fully off, run the cylinder through its 400 mm stroke, then close them gradually until end-of-stroke bounce disappears. The variable cushion works at each end, so faster 30-800 mm/s cycles run without hammering the aluminium covers.
