Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCM 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 MAC32X400SCM
Long 400 mm travel from a compact 32 mm round body is the MAC32X400SCM's job: double acting, variably cushioned at both ends, and rated 402.2 N push against 345.6 N pull at 0.5 MPa. The riveted stainless barrel and hard-chrome 12 mm rod take humid, occasionally hosed-down environments in stride.
On lift maths, 402.2 N corresponds to about 41 kg of hanging weight, so hold vertical payloads near 20 kg to preserve a 2:1 margin. The CM round-end cover suits clevis-style pivoted linkages, the standard piston magnet feeds CMSG / DMSG / EMSG switches, and the 1/8" ports accept PT, G or NPT threads.

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 MAC32X400SCM Is Used
Riser platform lift
Raises a 20 kg riser platform on an electronics test line - comfortably inside the roughly 41 kg vertical equivalent at 0.5 MPa, halved for margin.
Pusher transfer arm
Shuttles PCB carriers between two belt lanes on a 400 mm cross-transfer, guided externally so the chrome rod stays free of side load.
Saw-guard slide
Slides a guard across a beam-saw blade path; the round-end cover takes a clevis pin and the variable cushion quiets both ends of every cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X400SCM the Right Cylinder?
At 245.3 N push, a 25 mm bore handles lighter slides; at 628.3 N the 40 mm bore covers heavier dies - the 32 mm sits between with 402.2 N at 0.5 MPa. If the machine must hold position through an air loss, this cylinder has no internal lock: fit a pilot check valve or rod lock externally. Mount the round-end cover on a pivot pin or choose FA flange and LB foot brackets; with a 400 mm stroke, align the load axis carefully so the 12 mm rod sees no bending.
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 MAC32X400SCM FAQ
Use 402.2 N push and 345.6 N pull at 0.5 MPa as the working basis; at 0.7 MPa these grow to 563.0 N and 483.8 N, with 82 kgf as the theoretical maximum at 1.0 MPa. Operating band is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, ports 1/8" in PT (blank), G or T (NPT).
No - every MAC cylinder leaves the factory with the magnet already built in, so CMSG, DMSG and EMSG switches mount straight onto the barrel for end-of-stroke or mid-stroke sensing without a special order.
