Airtac MAC Stainless Steel Mini Air Cylinder MAC32X165SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X165SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 165mm 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 MAC32X165SU
Flat, fixed and fuss-free: the MAC32X165SU bolts its U flat-end back cover straight onto a machine face, no bracket needed. Underneath sits the classic MA build - a stainless round barrel rolled onto aluminium covers, a 20 um hard-chrome plated 12 mm rod, and a heterogeneous piston seal that stores grease between strokes.
It is double acting with a variable air cushion on both 165 mm ends, so it extends and retracts on air alone and arrives gently even at 800 mm/s. In force terms, 402 N of push at 0.5 MPa should be budgeted down to 241 N of true working load for long life. Mild corrosion, splash and washdown are all well within reach of the stainless barrel.

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 MAC32X165SU Is Used
Stop gate on a CNC chip conveyor
Pinned flush to the frame with the U flat end, it pops a stop gate into a CNC chip conveyor; 402 N of extend force holds the gate against parts arriving at up to 800 mm/s.
Indexer pin on a rotary dial table
The variable cushion lets the pin seat quietly into dial-table holes at speed; with 241 N of practical working force it indexes light aluminium fixture plates with margin to spare.
Tray ejector at a wash station
Daily splash and steam meet a stainless barrel and 20 um chrome rod, so the ejector pushes sample trays clear of a lab wash station without corroding.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X165SU the Right Cylinder?
Start from 402 N of push at 0.5 MPa: if your part needs less, the 25 mm bore delivers 245 N; if it needs more, the 40 mm bore delivers 628 N, both in the same MAC family. The U flat end bolts flush to a fixed face with no bracket, while FA, LB or SDB mounts and I/Y knuckles cover other layouts. Bear in mind the piston is free when air drops - fit a pilot check valve or rod lock to hold a load. At 165 mm of stroke, keep side forces on an external guide rather than on the 12 mm rod.
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 MAC32X165SU FAQ
At 0.5 MPa: 402 N extend, 346 N retract. At 0.7 MPa: 563 N extend, 484 N retract. Maximum theoretical: 82 kgf at 1.0 MPa. The bore 32 package carries 1/8" ports and an M10x1.25 rod thread on a 12 mm rod; pressure spans 0.15-1.0 MPa (22-145 psi).
The barrel is a stainless-steel tube with covers riveted on, and the 12 mm rod is carbon steel hard-chrome plated to 20 um, so it tolerates damp shop air, washdown and outdoor service far better than painted mini cylinders.
