Airtac MAC Stainless Steel Mini Air Cylinder MAC32X290SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X290SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 290mm 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 MAC32X290SCA
A 290 mm stroke in AirTAC's riveted round-body range, the MAC32X290SCA is double acting with a variable air cushion at each end, so the 12 mm hard-chrome rod starts and stops smoothly instead of hammering the covers. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa that rises to 563.0 N. The stainless barrel rolled onto aluminium covers handles washdown and damp plant air far better than a painted mini.
For day-to-day sizing, treat about 241 N (roughly six tenths of the 0.5 MPa push) as the working force, which corresponds to lifting about 20 kg vertically with a 2:1 margin. The piston magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on without a special-order piston, and the CA pivot back cover takes a clevis pin directly.

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 MAC32X290SCA Is Used
Pallet stacker lift
Raises a pallet layer about 20 kg through 290 mm on a low-cost stacker; the 2:1 vertical margin and cushioned stop keep the move smooth and safe.
Belt diverter gate
Swings a diverter arm across a parcel conveyor; 402.2 N push at 0.5 MPa swings the gate fast while the variable cushion kills the end-of-stroke bang.
Guard door operator
Slides a machine guard door on a CNC lathe; a CMSG switch on the standard magnet confirms full closure before the cycle starts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X290SCA the Right Cylinder?
At this bore class you sit between the MAC25 (245.3 N push at 0.5 MPa) and the MAC40 (628.3 N). If the job needs under about 241 N of working force, the 32 mm bore with cushioning is a comfortable match; step up to 40 mm for heavier clamps. Ports are 1/8 inch, rod thread M10x1.25, air 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Like every plain double-acting MAC, the rod free-drifts when the valve centres or air drops - add a rod lock or pilot check valve if the load must stay put. With 290 mm of stroke on a 12 mm rod, keep side loads off the rod and guide the load externally. FA flange, LB foot or SDB pivot brackets complete the mounting, while the CA cover handles clevis-style pivots.
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 MAC32X290SCA FAQ
At 0.5 MPa it pushes 402.2 N (about 41 kgf) and pulls 345.6 N; at 0.7 MPa the figures rise to 563.0 N push and 483.8 N pull. Theoretical peak is 82 kgf at 1.0 MPa. Running mechanisms at about 241 N of working push leaves room for friction and pressure drop.
The stainless tube plus a 20 um hard-chrome plated rod resists corrosion in washdown, food and outdoor spots that rust painted barrels. Each end carries a variable air cushion set by its own needle screw - back both off before the first run and close them gradually. The built-in magnet is standard, ready for CMSG, DMSG or EMSG switches.
