Airtac MAC Stainless Steel Mini Air Cylinder MAC32X75SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X75SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MAC32X75SU
A flat-end U back cover makes the MAC32X75SU the fixed-mount pick in the 32 mm family: bolt the round stainless body flat against a machine plate and the rod delivers 402.2 N forward or 345.6 N back at 0.5 MPa, scaling to 563.0 N at 0.7 MPa. Double-acting air with needle-adjusted cushions at each end means heavier loads stop soft instead of with a bang.
Inside, a two-way piston seal stores its own grease for long service; outside, the hard-chrome 12 mm rod and stainless tube handle damp shops and occasional washdown. Operating range is a wide 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating. For real-world sizing, count on about 241 N of usable force at 0.5 MPa rather than the full 402 N - and that works out to around 20 kg of vertical lift with a 2:1 safety factor.

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 MAC32X75SU Is Used
Divider blade actuator
Slides a divider blade in a parts-sorting magazine, bolted flat through the U cover against the magazine wall.
Bench crimper
Drives the jaw of a small bench crimper for terminal lugs, where the about 241 N working force at 0.5 MPa crimps small cross-sections cleanly.
Rack lane stop
Stops totes on a gravity rack lane in a humid 3PL warehouse, the stainless barrel resisting the condensation that pits painted bodies.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X75SU the Right Cylinder?
Against its neighbours, a 25 mm bore gives 245.3 N and a 40 mm bore 628.3 N at 0.5 MPa - pick 32 mm (402.2 N) when the mid-range fits the job. The U flat-end cover plus an optional FA flange or LB foot forms a rigid fixed base; add an SDB pivot bracket if the load must articulate. Since the MAC holds nothing on air loss - it drifts rather than locks - pair it with a rod lock or pilot check valve for suspended loads. Speed spans 30-800 mm/s, the fitting is 1/8", and the rod thread is M10x1.25.
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 MAC32X75SU FAQ
Catalogue figures: 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; 82 kgf theoretical maximum at 1.0 MPa. About 241 N at 0.5 MPa - roughly 20 kg lifted vertically with a 2:1 margin - is a safe working target.
It presents a flat machined face on the rear cover so the round body bolts straight to a machine plate without a pivot pin. Combine it with an FA flange or LB foot when the front end needs support too, and use I or Y rod knuckles on the load side. The built-in magnet still accepts CMSG, DMSG and EMSG switches.
