Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MAC32X450SUFA
A 450 mm stroke usually forces you into a bigger, heavier bore, but the MAC32X450SUFA keeps the 32 mm footprint and still pushes 402.2 N at 0.5 MPa (563.0 N at 0.7 MPa). It is double acting with a variable air cushion at both ends, and the FA flange bolts the body square to a fixed plate - a tidy choice for inline push rods that must stay coaxial. Vertically, the 0.5 MPa push equals about 41 kgf, so with a 2:1 margin you can lift around 20 kg.
The riveted stainless tube plus hard-chrome 12 mm rod combination is what makes this stroke practical in harsh shops: no painted surface to flake, no exposed fasteners to seize. Running limits are 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s. Every unit leaves the factory magnetised, so CMSG / DMSG / EMSG sensors mount at any mid-stroke point for zone or end-of-travel confirmation.

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 MAC32X450SUFA Is Used
Fixture clamp advance
Clamps long aluminium extrusions against a CNC stop, flange-mounted so thrust stays square to the vise.
Lane diverter
Pushes a diverter plate across a roller conveyor to route totes between two outbound lanes.
Feeder lift stage
Raises a light parts elevator platform the final 450 mm in an assembly cell feed system.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SUFA the Right Cylinder?
Compare forces before committing: 25 mm offers 245.3 N at 0.5 MPa and 40 mm offers 628.3 N, while this 32 mm sits between at 402.2 N. Keep steady-state duty near 241 N and let the full rating absorb spikes. Nothing in a standard double acting MAC parks the load - a centred valve or lost supply means a drifting rod - so pair it with a rod lock or pilot check where holding matters. For 450 mm of rod, mount the FA flange square to the thrust direction and support the load on external guides so side forces never reach the barrel.
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 MAC32X450SUFA FAQ
Push 402.2 N and pull 345.6 N 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. Stroke is 450 mm on a 12 mm rod with M10x1.25 thread, ports are 1/8", and rod speed runs 30-800 mm/s.
Yes - the variable air cushion at each end is tuned with needle screws on the covers. Back them fully off for the first run, then close gradually until the load stops cleanly; that protects the aluminium covers when a carriage arrives at speed after 450 mm of travel.
