Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCM 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 MAC20X130SCM
AirTAC built the MAC20X130SCM around a 20 mm bore and 130 mm stroke, closing the body with a round-end CM back cover for pivoting or clevis-style fixings. Double acting with a variable air cushion at both ends, it turns 0.5 MPa into 157 N of push and 131.9 N of pull, rising to 219.8 N of push at 0.7 MPa.
Inside is a stainless-steel tube with a hard-chrome carbon-steel rod; the aluminium covers are riveted onto the barrel, giving a sealed round body that holds up in wet and dusty corners. On a vertical lift the 157 N push is about 16 kg theoretical, and halving that for a 2:1 margin leaves a dependable 8 kg lifted load. Every unit includes the standard piston magnet that CMSG, DMSG and EMSG switches read.

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 MAC20X130SCM Is Used
Filling head lift
Raises a dosing nozzle assembly 130 mm between fill and rinse positions on a sauce filling machine, lifting about 8 kg with margin.
Drill jig clamp
Clamps aluminium brackets inside a light drilling fixture, the 219.8 N push at 0.7 MPa holding parts firm through the cycle.
Cap ejector on a trim press
Kicks finished bottle caps out of a small trimming die at end of cycle, the cushioned stop protecting the die face.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X130SCM the Right Cylinder?
Compare before you buy: bore 16 gives 100.5 N push at 0.5 MPa and bore 25 gives 245.3 N, so the 157 N of this 20 mm unit is the middle option. If the application must hold position with air off, note that the piston drifts freely - pair the cylinder with a rod lock or pilot check valve instead of relying on the cushion. The CM round-end cover takes a pivot pin directly; FA flange, LB foot and SDB pivot brackets, plus I and Y rod knuckles, cover the rest. The standard magnet means switch feedback is a bolt-on, not an option.
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 MAC20X130SCM FAQ
The 20 mm bore produces 157.0 N push and 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa, topping out at 32.0 kgf theoretical at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), fluid filtered to 40 um, speed 30-800 mm/s.
Yes. The magnet is built into the piston as standard, so CMSG, DMSG or EMSG switches clip into the barrel groove at any time. Mountings available to order include FA flange, LB foot, SDB pivot bracket and I or Y rod knuckles, on top of the CM round-end back cover supplied.
