Airtac MAC Stainless Steel Mini Air Cylinder MAC32X170SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X170SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 170mm 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 MAC32X170SU
A 32 mm bore round-body mini cylinder with a 170 mm stroke, the MAC32X170SU is double acting with a variable air cushion at both ends, so the rod decelerates softly whether it is pushing or pulling. At 0.5 MPa it develops 402 N of push and 346 N of pull, which covers medium clamping and sliding tasks in the 40 kg-force class. Running pressure is 0.15-1.0 MPa (22-145 psi) and rod speed spans 30-800 mm/s.
The stainless barrel and hard-chrome plated 12 mm rod stand up to washdown and damp shop air far better than painted-steel minis, a real edge in food plants and outdoor installations. Because the magnet is built in as standard, CMSG, DMSG or EMSG switches clamp straight onto the barrel without a special-order piston. As a working figure, plan on roughly 241 N of usable force at 0.5 MPa - about six tenths of the rating - and treat the 563 N push at 0.7 MPa as the ceiling for demanding cycles.

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 MAC32X170SU Is Used
CNC lathe part ejector
The 402 N push at 0.5 MPa clears machined steel housings out of a chuck fixture within the 170 mm throw, and the end cushion stops the ram hammering the cover at full speed.
Packaging line pusher
Mounted on a flow-wrap infeed, the cylinder slides tray stacks sideways between lanes; the stainless barrel tolerates the damp wipe-down routine between shifts.
Welding jig clamp arm
A toggle lever off the rod delivers clamp force to tube brackets; magnetic switches report open and closed positions to the PLC without drilling the body.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X170SU the Right Cylinder?
Between the 25 mm bore (245 N push at 0.5 MPa) and the 40 mm bore (628 N), this 32 mm unit sits in the middle for forces around 400 N. The cushion is not a brake: with the valve centred or air lost, the load drifts, so add a rod lock or pilot check valve if the position must be held. The flat-end U back cover suits fixed mounts, while FA flange, LB foot and SDB pivot brackets bolt on if the frame needs them. At 170 mm of stroke, keep side load off the 12 mm rod or guide the payload externally.
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 MAC32X170SU FAQ
At 0.5 MPa it pushes with 402 N and pulls with 346 N; at 0.7 MPa those figures rise to 563 N push and 484 N pull. The theoretical maximum is 82 kgf at 1.0 MPa (145 psi). Ports are 1/8", the rod is 12 mm with M10x1.25 thread, and the stroke is 170 mm.
Back both cushion needle screws fully off, then close them gradually until end-of-stroke knock disappears. The variable cushion at each end lets you tune deceleration across the 170 mm stroke at speeds up to 800 mm/s.
