Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 80mm stroke, 1/4" 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 MAC50X80SCM
Round-body and cushioned at both ends, the MAC50X80SCM puts 981 N of push at 0.5 MPa behind an 80 mm stroke while the CM round back cover keeps the rear of the cylinder neat and compact. Air drives the piston both ways - this is a double-acting unit, not a spring return - and the variable cushion screws let you soften arrival at full extension and full retraction as speeds climb toward the 800 mm/s top of the range.
Underneath, a stainless tube carries a hard-chrome plated rod that shrugs off packaging-hall moisture, coolant mist and outdoor weathering. For sizing, treat 589 N as the continuous working force at 0.5 MPa - about six tenths of the rated push - and the cylinder will run cool through long shifts. The magnet is built in from the factory rather than sold as an option, so CMSG, DMSG and EMSG switches snap onto the tube for end-of-stroke detection.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X80SCM Is Used
Lab fume-hood damper
Actuating a sash-linked damper in a university fume hood, where humid extracted air and aggressive cleaning agents corrode ordinary painted cylinders within a season.
PET tray denester
Feeding one PET tray at a time from a magazine at a salad-packing plant; the neat CM rear cover keeps the stack side tidy and the cushion drops each tray gently onto the flight.
Woodshop belt tensioner
Holding light tension on a return belt in a sawdust-heavy joinery shop, where the sealed rolling-packed barrel construction keeps debris away from the 16 mm chrome rod.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCM the Right Cylinder?
Weigh the lighter MAC32X80 (402 N at 0.5 MPa) against this 50 mm unit, or step up to the MAC63X80 (1558 N) for die pads and heavy slides. Keep in mind the rod is free to move once air is lost or the directional valve sits mid-position - a hanging load will creep, so fit a rod lock or pilot check valve where holding matters. The CM round rear cover suits direct frame bolting, extended by FA flange, LB foot and SDB mounts, while the factory magnet already inside supports CMSG, DMSG and EMSG sensing. Ports are 1/4", speed spans 30-800 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi).
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 MAC50X80SCM FAQ
At 0.5 MPa supply the rod pushes 981 N and retracts with 881 N. At 0.7 MPa expect 1374 N on extend and 1233 N on retract. Maximum theoretical output at 1.0 MPa is 200 kgf.
The riveted stainless tube together with the 20 um hard-chrome plated rod resists rust, moisture and mild chemicals, so it survives washdown areas, coolant mist and outdoor duty that quickly ruin painted-steel housings.
