Airtac MAC Stainless Steel Mini Air Cylinder MAC32X230SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X230SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 230mm 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 MAC32X230SU
The MAC32X230SU pairs a 32 mm bore with a 230 mm stroke inside AirTAC's riveted round-body construction: stainless barrel, hard-chrome plated 12 mm rod, aluminium covers rolled onto the tube for a sealed joint. Double acting and cushioned at both ends, it pushes 402 N and pulls 346 N at 0.5 MPa.
Because the U cover presents a flat threaded face, the cylinder bolts straight onto plates and machine walls - fewer brackets than a pivot style. Run it on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s, and budget around 241 N of dependable working force once you derate to 60% of the push 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 MAC32X230SU Is Used
Pusher on a sortation spur
Kicking parcels onto a takeaway belt at up to 800 mm/s, the flat U-face mount bolted directly to the conveyor side rail.
Slide gate on a gravity hopper
Opening and closing a hopper gate where the round stainless body bolts flush against a simple gate bracket, cushions easing the gate home.
Bench-top pressing station
Applying 402 N at 0.5 MPa to press bushings into housings, with the variable cushion softening ram contact with the part.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X230SU the Right Cylinder?
Compared with the MAC25 (245 N push at 0.5 MPa) this bore gives about 64% more force; step up to the MAC40 (628 N) if the load grows. Like any double-acting cylinder without a lock, the rod creeps if supply air is lost, so add a pilot check valve for held loads. On a 230 mm stroke, guide the load externally or use a rod knuckle to keep side thrust off the 12 mm rod and out of the bushings.
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 MAC32X230SU FAQ
Expect 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, and a theoretical peak of 82 kgf at 1.0 MPa. Bore 32 takes 1/8" ports and an M10x1.25 rod thread; supply air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and stroke between 30 and 800 mm/s.
The barrel is stainless steel with the covers rolled on rather than clamped, so there are fewer leak paths and the body tolerates washdown and humid shops far better than painted or plain aluminium minis. The 20 um hard-chrome rod adds wear life, and the standard magnet works with CMSG, DMSG and EMSG switches out of the box.
