Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 440mm 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 MAC32X440SCA
Longest travel in the 32 mm class, MAC32X440SCA reaches 440 mm while delivering 402 N push and 346 N pull at 0.5 MPa. Air cushioning is variable at both ends, so the needle screws can be opened until a 440 mm swing or push lands dead silent, then set once for production.
The CA pivot back cover makes it a natural fit for hinged and lever mechanisms, while the riveted stainless barrel and hard-chrome rod resist mild corrosion in wet plants. Plan the mechanism around roughly 241 N of real work rather than the full rating, and the cushion and seals stay stable through long duty cycles.

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 MAC32X440SCA Is Used
Hinged hopper gate dosing
Tipping a small hopper gate to dose granules into filler bowls, the swing driven by 402 N at 0.5 MPa.
Clamp-and-swing fixture
Swinging a welding fixture arm out of the robot cell on a 440 mm stroke, position read by EMSG switches.
Test-stand lever loading
Applying a levered force to bicycle brake levers on a durability rig, with the cushion tuned to avoid impact spikes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X440SCA the Right Cylinder?
A 25 mm bore pushing 245 N at 0.5 MPa handles shorter, lighter swings; a 40 mm bore with 628 N takes over when the mechanism is stiff or the load heavy. I or Y rod knuckles in the CA pivot line keep bending stress off the 12 mm rod across the 440 mm span.
Remember the piston is free to move when air is removed or the valve centres - the cushion slows motion but does not lock it, so add a pilot check valve or rod lock for held positions. FA flange and LB foot mounts, or an SDB pivot bracket, anchor the body wherever the CA cover is not the mounting point.
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 MAC32X440SCA FAQ
At 0.5 MPa: 402 N push and 346 N pull. At 0.7 MPa: 563 N push and 484 N pull. Maximum theoretical force is 82 kgf at 1.0 MPa. Bore is 32 mm with 1/8" ports and a 12 mm rod in M10x1.25 male thread; speed range is 30-800 mm/s over 0.15-1.0 MPa (22-145 psi).
The magnet comes built into the MAC32X440SCA piston as standard - no special-order piston is needed. CMSG, DMSG and EMSG switches simply clamp onto the stainless barrel and signal rod position at any point along the 440 mm travel, ideal for confirming both ends of a long swing or push.
