Airtac MAC Stainless Steel Mini Air Cylinder MAC20X370SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X370SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 370mm 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 MAC20X370SCM
Round-ended and simple to clamp, the MAC20X370SCM spans 370 mm while pushing 157 N at 0.5 MPa and pulling 131.9 N on the return. It is double acting with a variable air cushion at both ends, running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.
Unlike painted mini barrels, the stainless tube with a 20 um hard-chrome rod takes humid washdown corners without flaking. The CM round-end back cover bolts to fixed plates without a bracket, and since the magnet comes standard, CMSG or EMSG switches snap on for end-of-travel proof. In practice keep working force near 94 N at 0.5 MPa, which is enough to raise about 8 kg against gravity with margin to spare.

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 MAC20X370SCM Is Used
Sample pusher
Slides sample racks 370 mm into an incubator shelf; the stainless barrel tolerates daily disinfectant wipes.
Feeder gate
Opens a hopper gate on a granule feeder; 157 N at 0.5 MPa trips the gate and the cushion stops the slam.
Index probe
Extends a probing tip onto moving cartons and confirms position through an EMSG switch on the standard magnet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X370SCM the Right Cylinder?
Compare before you commit: bore 16 offers 100.5 N at 0.5 MPa and bore 32 climbs to 402.2 N, so 20 mm covers mid-light pushes where space is tight. With 370 mm of stroke, guide long side loads and avoid cantilevering the rod. When the valve centres, the rod moves freely - fit a rod lock or pilot check valve if the load must stay put. FA flange, LB foot and SDB pivot brackets bolt to the same body if the CM round end is not the match.
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 MAC20X370SCM FAQ
At 0.5 MPa the cylinder pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N. Maximum theoretical force is 32 kgf at 1.0 MPa. Air supply spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speed runs 30-800 mm/s.
It replaces the pivot ears with a flat round flange, so the cylinder screws directly onto a machine plate without extra brackets. The stainless barrel stays the same - riveted, sealed and washdown friendly - and the built-in magnet still lets CMSG, DMSG or EMSG switches read position off the tube.
