Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MAC20X50SCA
A 50 mm stroke on a 20 mm bore keeps this MAC compact enough to hide inside a machine frame while still delivering 157 N of push at 0.5 MPa. It is double acting with a variable cushion at each end, so even short cycles at high speed land quietly. Working pressure spans 0.15-1.0 MPa (22-145 psi).
Budget about 94 N for real work at 0.5 MPa - roughly an 8 kg vertical lift with a 2:1 margin - and the cushion screws will tune out residual shock. The stainless round barrel and chrome-plated rod tolerate damp shop air, and because the magnet ships standard, a CMSG or DMSG switch simply clamps on for end-of-stroke feedback.

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 MAC20X50SCA Is Used
Bottling line flipper
Flips a lay-down bottle upright on a 50 mm pitch; the short stroke cycles fast with both ends cushioned, right up to the 800 mm/s top speed.
Weld fixture clamping pin
Inserts a locating pin into a car-door welding fixture; about 94 N of working force at 0.5 MPa seats the pin without marking the panel.
Trim press part eject
Ejects a trimmed gasket from a shallow die; a CMSG switch on the standard magnet confirms full retraction before the press cycles again.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X50SCA the Right Cylinder?
Lighter duty up to 100.5 N suits the 16 mm bore; heavier 50 mm-stroke work calls for the 25 mm bore at 245.3 N. When the valve goes to centre the rod is free to move under load - plan a rod lock or external stop for anything that must stay clamped. CA pivot plus an SDB bracket or Y knuckle suits swing motions, and the magnet is already in the piston for CMSG sensing.
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 MAC20X50SCA FAQ
It extends with 157 N and retracts with 131.9 N at 0.5 MPa; at 0.7 MPa the figures are 219.8 N and 184.7 N, with about 32 kgf theoretical at 1.0 MPa. Ports are 1/8 inch and the rod thread is M8x1.25 on an 8 mm rod.
The pivot only shapes the mounting - it holds nothing. When the valve centres, the rod drifts with the load, so use a rod lock or a pilot check valve wherever a parked position matters. For swing motion, pair the CA cover with an SDB bracket or I/Y rod knuckles.
