Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 275mm 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 MAC32X275SCA
Covering mid-range work, the MAC32X275SCA is a double-acting mini cylinder with a 32 mm bore and a 275 mm stroke, moving at 30-800 mm/s across 0.15-1.0 MPa (22-145 psi) supply. At 0.5 MPa it pushes 402 N, and since roughly 60% of that rating should carry the real job, plan on about 241 N of usable force - enough to slide or index loads in the 20 kg class with margin to spare.
The riveted stainless round barrel and hard-chrome plated rod shrug off washdown and humidity far better than painted-steel minis, which matters in food plants and outdoor fixtures. A variable air cushion sits at both ends: back the needle screws off for the first run, then close gradually to soak up end-of-stroke shock so faster speeds or heavier loads never hammer the covers.

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 MAC32X275SCA Is Used
Bottling line gate
Swinging a guide gate across a 275 mm bottle path on a filler conveyor, with the pivot back cover taking the swing motion directly.
Indexing pusher
Advancing product trays into position on a packaging indexer at 30-800 mm/s, using the air cushion to land each tray without a bang.
Test rig actuator
Applying about 241 N of working push in a leak or endurance test station where the stainless barrel tolerates daily wipe-downs.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X275SCA the Right Cylinder?
Step down to the MAC25X50 family (245 N push at 0.5 MPa) for lighter gates, or step up to a 40 mm bore (628 N) when the load climbs past about 350 N of real work. Like every MAC, this one is double acting with no position hold: kill the air and the piston drifts, so fit a rod lock or pilot check valve where the load must stay parked.
The CA pivot back cover accepts a clevis or trunnion-style pivot without extra brackets, and FA flange or LB foot mounts bolt on if the frame is fixed. Magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on for end-of-stroke signalling. At 275 mm of stroke, guide the load externally and keep side force off the 12 mm rod to avoid 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 MAC32X275SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. Raise supply to 0.7 MPa and push rises to 563.0 N with pull at 483.8 N; the theoretical ceiling at 1.0 MPa is 82 kgf. Ports are 1/8" on this 32 mm bore and the rod thread is M10x1.25.
A magnet is built into the piston as standard, not an option, so AirTAC CMSG, DMSG and EMSG reed or electronic switches mount directly on the barrel for end-of-stroke detection without a special-order piston.
