Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 130mm 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 MAC20X130SCA
Pivot duty straight from the box: the CA eye in the rear cover lets the MAC20X130SCA swing through arcs with no clevis bracket to source. This 20 mm bore generates 157 N of push and 131.9 N of pull at 0.5 MPa, rising to 219.8 N and 184.7 N at 0.7 MPa with a 32 kgf theoretical peak. Budget about 94 N - roughly six tenths of the rated push - as the force available for real work and the seals and sliding surfaces will last. Supply it 0.15-1.0 MPa (22-145 psi) of 40 um filtered air.
A riveted, round stainless barrel with a hard-chrome carbon-steel 8 mm rod stands up to splash and humidity where painted minis corrode, and the aluminium-alloy covers keep the package light. The piston magnet is included as standard equipment, so CMSG, DMSG or EMSG reed switches fit without a special-order piston. Variable air cushions at both ends absorb the deceleration, letting the cylinder cycle up to 800 mm/s cleanly.

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 MAC20X130SCA Is Used
Tray tipper
Tilts a small inspection tray 90 degrees on its CA pivot pin to present a machined part to an operator or vision camera.
Swing diverter
Swings a diverter arm across a food-grade conveyor lane to route packs, riding out washdown splash on the stainless barrel.
Rocking clamp
Rocks a clamp arm onto castings on a machining fixture, using about 94 N of working force and the pivot eye for natural alignment.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCA the Right Cylinder?
Compare before ordering: bore 16 gives 100.5 N and bore 25 gives 245.3 N at 0.5 MPa, placing this 157 N size between them for light gates and tilt motions. There is no internal lock - with supply lost the piston free-strokes, so fit a pilot check valve or rod lock to hold a suspended arm. The rear CA eye pairs naturally with an SDB pivot bracket, while an LB foot, FA flange or a different back cover can be ordered instead if fixed mounting wins. Keep the 130 mm stroke guided if the work introduces side force.
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 MAC20X130SCA FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa expect 219.8 N push and 184.7 N pull; the theoretical peak is 32 kgf at 1.0 MPa. Porting is 1/8" (bore 20), the rod is 8 mm with an M8x1.25 thread, and 130 mm is a standard stroke - the bore allows up to 500 mm.
Yes - the stainless round barrel plus the 20 um hard-chrome plated carbon-steel rod resist the humidity, splashes and periodic washdown that corrode painted-steel mini cylinders. The covers are riveted onto the tube, so there are no tie-rod fasteners to loosen in a damp environment.
