Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MAC32X250SCA
A riveted round-body mini cylinder rather than a tie-rod design, the MAC32X250SCA wraps a 250 mm stroke around a 32 mm stainless barrel with aluminium-alloy covers rolled on for a sealed body. It is double acting, so air both extends and retracts the rod, and a variable air cushion sits at each end. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the push rises to 563.0 N.
The CA pivot back cover lets the cylinder swing in a linkage without added brackets. Because the magnet is built in as standard, CMSG, DMSG or EMSG switches clip on for end-of-stroke signals. The cushion lets you back the needle screws off, then close them gradually to tame end-of-stroke shock at speeds up to 800 mm/s. For sizing, count on roughly 241 N of real working force at 0.5 MPa instead of the full 402.2 N rating.

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 MAC32X250SCA Is Used
Carton pusher on a packaging conveyor
A 250 mm stroke and 402 N push at 0.5 MPa divert a 20 kg carton row sideways; the stainless barrel shrugs off daily wipe-downs.
Lid-lift on a washdown food hopper
Pivoting from the CA back cover, the cylinder raises a hopper lid; the hard-chrome rod resists moisture where painted minis corrode.
Fixture clamp on a welding jig
About 241 N of working force holds steel brackets in place while a CMSG switch confirms the closed position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCA the Right Cylinder?
Step down to the MAC25 bore if 245.3 N at 0.5 MPa covers the job; step up to the MAC40 bore for 628.3 N. The 250 mm stroke rewards attention to side loads: guide the load externally and keep the M10x1.25 rod thread square to its fitting. Remember a plain MAC drifts when air is removed or the valve centres, so fit a rod lock or pilot check valve where a position must hold. Mounting choices beyond the CA pivot include FA flange, LB foot and SDB pivot bracket, ports are 1/8", and supply runs 0.15-1.0 MPa (22-145 psi).
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 MAC32X250SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa the push is 563.0 N and the pull 483.8 N. The theoretical maximum at 1.0 MPa is 82 kgf. Ports are 1/8", the rod is 12 mm with an M10x1.25 male thread, and speed runs 30-800 mm/s over an operating range of 0.15-1.0 MPa (22-145 psi).
No. As a double-acting cylinder without a lock, the rod moves freely once air pressure is gone or the valve sits centred, and the cushion is not a brake. Add a rod lock or a pilot check valve when the 250 mm stroke must stay put under load.
