Airtac MAC Stainless Steel Mini Air Cylinder MAC32X15SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X15SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 15mm 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 MAC32X15SU
At 15 mm of travel, the MAC32X15SU is a short-shuttle double acting cylinder: air drives the rod out and pulls it back, with a variable air cushion trimming both ends. On a 32 mm bore that means 402 N of push and 346 N of pull at 0.5 MPa, enough to snap small parts into nests or eject them off a die in one quick 15 mm hit.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated rod, so coolant mist or occasional washdown does not chew through a painted shell. Plan on roughly 241 N of usable push at 0.5 MPa rather than the full rating, and because the magnet ships built in, CMSG or DMSG switches clip on when you need end-of-stroke signals.

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 MAC32X15SU Is Used
Short-stroke part ejection
Kicking formed blanks off a stamping die face in one 15 mm jab at up to 402 N.
Gate or clamp actuation
Snapping a small drill-press guard gate or jig clamp shut where 15 mm of travel is all the clearance allows.
Signal repeater on a fixture
Pushing a limit-flag through a fixture plate with a CMSG switch confirming the clamped position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X15SU the Right Cylinder?
A 15 mm stroke does indexing and ejection work, so match the force, not the travel: the 25 mm bore delivers only 245 N at 0.5 MPa, while stepping up to 40 mm gives 628 N if your nest needs more clout. Running pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
Like every unvalved double acting cylinder, this one drifts the moment air is removed - it will not park itself at the 15 mm mark without a check valve or rod lock. The U flat-end cover bolts straight to a plate with no pivot bracket, and LB foot or FA flange hardware is there if the fixture changes.
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 MAC32X15SU FAQ
At 0.5 MPa the 32 mm bore pushes 402 N and pulls 346 N; at 0.7 MPa those rise to 563 N and 484 N. The theoretical ceiling is 82 kgf at 1.0 MPa. Port size is 1/8" and the rod is 12 mm with an M10x1.25 male thread, valid across the whole 15 mm stroke.
Short-stroke cylinders often live inside machines where coolant, chips and splashes collect. The MAC32X15SU's stainless barrel and 20 um hard-chrome rod tolerate that damp environment, and the two-way piston seal retains grease for long service between rebuilds.
