Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCMLB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCMLB 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 MAC32X450SCMLB
With 402.2 N of push at 0.5 MPa behind a 450 mm stroke, the MAC32X450SCMLB handles long-travel work most round mini cylinders cannot reach. It is double acting - air drives the rod out and back - and a variable air cushion at both ends soaks up end-of-stroke shock, so you can run the full 30-800 mm/s speed range against loaded slides without hammering the covers. Ports are 1/8", the rod is 12 mm with an M10x1.25 male thread, and the LB foot base bolts the body straight to a machine plate.
The barrel is stainless steel rolled up with aluminium-alloy covers, a riveted package that shrugs off washdown and damp plant air where painted minis blister. The 20 um hard-chrome rod keeps seal wear low over 450 mm of travel. A magnet is built in as standard, so CMSG / DMSG / EMSG switches drop straight on. For sizing, plan real duty around 241 N at 0.5 MPa, and with a 2:1 margin that is about 20 kg of vertical lift.

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 MAC32X450SCMLB Is Used
Case-line pusher
Bolts under a case-packing conveyor and sweeps cartons 450 mm onto a takeaway belt in one smooth, cushioned cycle.
Washdown gate drive
Drives a stainless slide gate on a dairy CIP line, where the riveted stainless body shrugs off daily hose-down.
Tray shuttle
Indexes bakery tray stacks along a rack conveyor rail, with end-of-stroke cushioning so loaded stacks stop without a bang.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X450SCMLB the Right Cylinder?
Between bores: 25 mm gives 245.3 N push at 0.5 MPa - roughly half this model's work - while 40 mm steps up to 628.3 N if the load grows. Because nothing in a plain double acting MAC locks the piston, expect drift whenever the valve centres or supply drops; add a rod lock or pilot check valve where the position must hold. On a 450 mm stroke, guide the load externally and keep side force off the 12 mm rod to protect the barrel bore. LB foot mounting pairs with SDB pivot brackets, FA flanges and I / Y rod knuckles if the linkage needs them.
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 MAC32X450SCMLB FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa those rise to 563.0 N and 483.8 N. The theoretical ceiling is 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
The LB feet bolt the 32 mm barrel to a flat plate, and the CM round-end rear cover accepts a pivot pin if you later want a swing linkage. The magnet is fitted as standard, so CMSG, DMSG and EMSG switches clip onto the 450 mm barrel anywhere along the stroke without ordering a special piston.
