Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SU
The AirTAC MAC Stainless Steel Mini Air Cylinder MAC32X85SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 85mm 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 MAC32X85SU
Built on a riveted stainless-steel barrel with a hard-chrome plated rod, this 32 mm mini cylinder shrugs off washdown and damp air that would rust painted-steel minis. It is double acting - air extends and retracts the rod - with a variable air cushion at both ends, so end-of-stroke shock can be dialled out and loads run faster without hammering the covers.
At 0.5 MPa the bore delivers 402.2 N on extend and 345.6 N on retract; size real work at roughly 241 N to keep a healthy margin. The 85 mm stroke suits short push-and-clamp moves, and because the magnet is standard, CMSG, DMSG or EMSG switches clip on without a special-order piston.

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 MAC32X85SU Is Used
Fixture clamping
Push-and-clamp on CNC milling fixtures where about 241 N of working force secures aluminium parts through a short 85 mm throw.
Cap seating on a bottling line
Seating caps or plugs on a small bottling station; the stainless barrel handles daily wipe-downs in wet areas.
Slide feed on assembly stations
Feeding small housings along a slide, with CMSG switches confirming both end positions.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SU the Right Cylinder?
Sitting between the 25 mm bore (245.3 N push at 0.5 MPa) and the 40 mm bore (628.3 N), the 32 mm covers mid-range clamping and feeding jobs. If the piston must hold position with air off, remember it drifts freely - fit a rod lock or pilot check valve instead. The U flat-end back cover gives a fixed, bracket-free mount; add FA flange, LB foot or SDB pivot hardware if the frame needs it. Air ports are 1/8 inch per end.
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 MAC32X85SU FAQ
At 0.5 MPa this 32 mm bore pushes 402.2 N and pulls 345.6 N. Raise supply to 0.7 MPa and push rises to 563.0 N (pull 483.8 N); theoretical maximum is 82.0 kgf at 1.0 MPa. Air supply range is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
Back both cushion needle screws fully off before start-up, then close them gradually until end-of-stroke bounce disappears. The cushion is variable, so tune it to each load and speed rather than leaving it fully shut, which can stall the piston short of stroke.
