Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCASDB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCASDB 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 MAC32X450SCASDB
Pivoting motion is what this version is built for: a CA pivot back cover plus an SDB pivot bracket let the MAC32X450SCASDB swing on a pin straight out of the box. The 32 mm double-acting bore pushes 402.2 N and pulls 345.6 N at 0.5 MPa - 563.0 N and 483.8 N at 0.7 MPa, 82 kgf theoretical maximum.
The riveted stainless round body handles damp and lightly corrosive sites far better than painted minis, and the hard-chrome plated 12 mm rod keeps sealing surfaces smooth over the long 450 mm stroke. Variable air cushions at both ends absorb the swing-in shock of a loaded chute or arm. Plan the job around about 241 N of usable force - near 60% of the 0.5 MPa push - and the built-in magnet will drive CMSG / DMSG / EMSG switches without ordering a special 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 MAC32X450SCASDB Is Used
Hopper flap gate
Tipping a flap gate on a feed hopper through its arc - the SDB pivot tracks the rotation while 402 N at 0.5 MPa works against the product head load.
Swing ejector arm
Knocking finished parts off a CNC fixture with a swing arm; the cushioned stops keep the arm from cracking against the frame at high cycle rates.
Pallet stopper lever
Raising and lowering a stopper lever on a pallet conveyor line, where the stainless barrel tolerates a dusty, occasionally washed corridor.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCASDB the Right Cylinder?
Loads needing less than about 245 N at 0.5 MPa fit a 25 mm bore; anything over roughly 628 N belongs on the 40 mm model. At 450 mm stroke the pivot mount helps the cylinder follow linkage arcs, but still guide heavy loads so the rod sees little side force. Position is not held if air fails or the valve centres - add a pilot check valve or rod lock for suspended arms. FA flange and LB foot options cover fixed-frame installs, with I / Y knuckles on the rod.
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.
