Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 85mm 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 MAC32X85SCM
The round-end CM back cover on the MAC32X85SCM suits linkages and clevis-style connections where a flat face would foul. This 32 mm bore, 85 mm stroke unit is double acting with an adjustable air cushion at both ends, pushing 402 N and pulling 346 N at 0.5 MPa; at 0.7 MPa output climbs to 563 N push and 484 N pull, peaking at a theoretical 82 kgf. Its stainless barrel and chrome-plated rod stand up to moisture that ruins painted minis.
Mounting flexibility is the story here: the CM round end pairs with SDB pivot brackets, while FA flange and LB foot options cover fixed frames. The piston magnet is standard equipment, so position feedback via CMSG, DMSG or EMSG switches needs no special order. In practice, budget about 241 N of working force at 0.5 MPa - the equivalent of lifting some 20 kg vertically at a 2:1 margin - and you will size with headroom.

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 MAC32X85SCM Is Used
Vision station lift
Raises each machined bushing into the camera's focal plane at an inspection cell, with a DMSG switch confirming the up position.
Carton flap tucker
Folds the leading flap of a 200 mm carton on a case erecting line, the cushion preventing a hard slap at full extension.
Idler roll tensioner
The round-end cover pivots an idler roller against film web on a bag-making machine to hold steady web tension.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCM the Right Cylinder?
If 402 N at 0.5 MPa overshoots the job, the 25 mm bore delivers 245 N; if it falls short, the 40 mm bore offers 628 N on the same supply. Do not treat the cushion as a brake - start with the needle screws backed off, adjust them in gradually on commissioning, and fit a check valve or rod lock wherever position must persist without air. The rod thread on this bore is M10x1.25 male, and side loads over the 85 mm stroke should be carried by external guides, not the 12 mm 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.
Airtac MAC Stainless Steel Mini Air Cylinder MAC32X85SCM FAQ
Expect 402 N push and 346 N pull at 0.5 MPa from the 32 mm bore, 563 N push and 484 N pull at 0.7 MPa, and a theoretical 82 kgf maximum at 1.0 MPa. The rod is 12 mm with M10x1.25 male thread, ports are 1/8", the 85 mm stroke sits inside the 500 mm standard ceiling, and it runs on 0.15-1.0 MPa (22-145 psi).
Both ends have adjustable air cushions driven by needle screws. Start with them backed off, run the cylinder slowly, then close each needle a little at a time until the 85 mm stroke ends smoothly - this protects the aluminium covers when cycling fast or carrying loads near the 402 N rating.
