Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCA 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 MAC32X450SCA
Double acting on both strokes with adjustable air cushions at each end, this 32 mm MAC gives you 402.2 N of push and 345.6 N of pull at 0.5 MPa, climbing to 563.0 N / 483.8 N at 0.7 MPa (82 kgf theoretical peak). Because the cushions are needle-adjustable you can run faster cycles or heavier loads without the covers taking a hammering.
The 450 mm stroke suits long gates and ejectors, and the CA pivot back cover takes a clevis or pin directly, no adapter bracket needed. Construction is the classic riveted round body: stainless barrel, hard-chrome 12 mm rod, aluminium covers. A magnet is fitted as standard, so CMSG / DMSG / EMSG switches snap on when you need end-of-stroke confirmation. Expect roughly 20 kg of vertical lift with a 2:1 margin, based on the 402.2 N at 0.5 MPa.

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 MAC32X450SCA Is Used
Silo slide gate
Opening a slide gate on a grain silo outlet - 402 N at 0.5 MPa works against column pressure, and the CA pivot follows the gate linkage directly.
Scrap chute diverter
Swinging a chip conveyor diverter between two bins; the needle cushions settle the heavy chute quietly into each stop anywhere in the 30-800 mm/s range.
Tray ejector
Pushing loaded baking trays off a rack loader - 345.6 N of return force retracts against tray friction, with a DMSG switch confirming full retract.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCA the Right Cylinder?
Step down to a 25 mm MAC (245.3 N push at 0.5 MPa) if the load is light, or up to 40 mm (628.3 N) if you are near the limit. Over a 450 mm stroke, keep side load off the rod with external guides - rod bending grows quickly at this length. This cylinder cannot hold a load when air is lost or the valve centres; fit a pilot check valve or rod lock where holding matters. SDB pivot bracket, FA flange and LB foot mounts are available.
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 MAC32X450SCA FAQ
402.2 N push / 345.6 N pull at 0.5 MPa and 563.0 N push / 483.8 N pull at 0.7 MPa, peaking at 82 kgf theoretical at 1.0 MPa. Fluid is 40 um filtered air at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, ports 1/8", rod thread M10x1.25.
Back both cushion needle screws fully off before the first stroke, then close them gradually until end-of-stroke noise and bounce disappear. The variable air cushion works independently at each end, so extend and retract stops can be tuned separately across the 30-800 mm/s speed range.
