Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MAC32X250SCM
Double acting with a variable air cushion at both ends, the MAC32X250SCM generates 402.2 N of push and 345.6 N of pull at 0.5 MPa, climbing to 563.0 N at 0.7 MPa. Its 32 mm bore sits inside a rolled stainless-steel barrel, and the covers are riveted on, so there are no tie-rods to loosen. The CM round-end back cover gives a compact fixed mounting face.
For vertical work, the 402.2 N push equals about 41 kg of theoretical lift at 0.5 MPa; halving for a 2:1 margin means it comfortably raises roughly 20 kg part weights. The cushion absorbs end-of-stroke shock so you can push cycling toward 800 mm/s without hammering the covers, and the standard magnet accepts CMSG, DMSG and EMSG switches for position signals. Duty runs -20 to +70 C on air filtered to 40 um.

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 MAC32X250SCM Is Used
Raising a stamping nest in a press shop
With about 41 kg of theoretical lift at 0.5 MPa the cylinder elevates a 20 kg nest between cycles; the cushion eases it home.
Reagent tray indexing in a lab filler
The 250 mm stroke advances trays one station at a time while DMSG switches confirm each position.
Gate actuator on a water-treatment sluice
Outdoors, the stainless barrel and hard-chrome rod shrug off spray that corrodes painted mini cylinders.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X250SCM the Right Cylinder?
Below this bore, the MAC25 manages 245.3 N at 0.5 MPa; above it, the MAC40 reaches 628.3 N, so the 32 mm size fits mid-range clamping and pushing. Keep the 250 mm stroke straight by guiding long or offset loads on external slides to protect the 12 mm rod. If the application must hold a part against gravity or spring force, remember this cylinder drifts without air; specify a rod lock or pilot check valve alongside. The CM round end pairs with FA flange, LB foot or SDB pivot brackets if a fixed face alone is not enough.
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 MAC32X250SCM FAQ
Size against 402.2 N push and 345.6 N pull at 0.5 MPa, or 563.0 N push and 483.8 N pull at 0.7 MPa; the theoretical ceiling is 82 kgf at 1.0 MPa. The bore is 32 mm, the port 1/8", and the rod thread M10x1.25.
It gives a clean fixed face instead of the CA pivot style, so brackets sit flush against machine plates; FA flange, LB foot and SDB pivot mounts remain available. The variable air cushion at each end still adjusts with needle screws, which should be opened fully on first run and closed gradually.
