Airtac MAC Stainless Steel Mini Air Cylinder MAC20X310SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X310SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 310mm 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 MAC20X310SCM
Long-travel work in a slim bore is the brief here: 310 mm of stroke inside a 20 mm stainless round body, double acting with a variable cushion at each end. Push is 157 N at 0.5 MPa and 219.8 N at 0.7 MPa, ample for gates, ejectors and probes along the full travel.
The covers and a stainless block are rolled onto the barrel, giving a slim sealed round body that shrugs off splash and humidity better than painted minis. The CM round-end cover accepts a pivot pin directly, handy for swinging linkages. Match real part weight before you buy: at 0.5 MPa the bore theoretically lifts 16 kg, so keep to about 8 kg vertical for a 2:1 margin.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X310SCM Is Used
Carton diverter in a warehouse sorter
Swings a diverter across a 300 mm carton lane; the CM round end carries the pivot pin without extra brackets.
Sample pusher on a lab analyzer
Advances sample trays a fixed 310 mm into the measuring station, cushioned at both ends for gentle placement.
Foil cover slide on a blister machine
Draws the foil cover back on a semi-automatic blister packer where a slim round body fits the frame.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X310SCM the Right Cylinder?
Lighter gates can drop to a 16 mm bore at 100.5 N push; heavier tooling steps up to the 25 mm bore and 245.3 N at 0.5 MPa. On a 310 mm stroke, guide the load on external rails or a bushing so side forces never bend the 8 mm rod. Position is not retained when air drops or the valve centres - a pilot check valve or rod lock handles held loads. Mount with FA flange or LB foot brackets; the standard magnet pairs with CMSG and EMSG switches, and the operating window is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
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 MAC20X310SCM FAQ
At 0.5 MPa: 157 N extend, 131.9 N retract. At 0.7 MPa: 219.8 N extend and 184.7 N retract. The theoretical ceiling at 1.0 MPa is 32 kgf. Work with roughly 94 N continuously for a dependable margin.
No. Every MAC cylinder carries a piston magnet as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel and signal end-of-stroke without any special-order piston.
