Airtac MAC Stainless Steel Mini Air Cylinder MAC20X45SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X45SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 45mm 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 MAC20X45SCA
With a CA pivot back cover, the MAC20X45SCA swings on its pivoting mount instead of needing a separate bracket, which keeps short 45 mm stroke linkages tidy. It pushes 157 N and pulls 131.9 N at 0.5 MPa, so it comfortably lifts about 8 kg vertically once you keep a 2:1 margin.
Air cushioning at both ends is variable - open the needle screws on commissioning and close them until the impact fades - so you can run up to 800 mm/s without cracking the covers. The stainless round barrel and hard-chrome 8 mm rod cope with splash and humidity, and the built-in magnet is standard equipment, ready for CMSG or DMSG position switches.

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 MAC20X45SCA Is Used
Hinge-arm clamp
Pivots a hold-down arm onto an aluminium extrusion before drilling; the CA pivot cover mounts straight onto the fixture pin with no bracket plate.
Rotary index detent
Seats a pawl on a rotary indexing table between positions; 157 N at 0.5 MPa locks the detent and the short 45 mm stroke keeps cycle time tight.
Vial capping press
Presses caps onto 30 ml sample vials in a lab autosampler; the about 94 N practical force seats caps firmly without cracking glass.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X45SCA the Right Cylinder?
For a 45 mm job, compare the 16 mm bore at 100.5 N and the 25 mm bore at 245.3 N, both at 0.5 MPa - stay at 20 mm if roughly 94 N of usable force covers your load. The CA pivot suits swinging linkages; switch to the U flat-end or CM round-end cover, or add FA flange, LB foot or SDB pivot mounts, for fixed installations. Remember this cylinder cannot hold a load against gravity once air is removed - it will drift, so fit a rod lock or pilot check valve for suspended positions.
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 MAC20X45SCA FAQ
Placeholder
Every MAC20X45SCA leaves the factory with the piston magnet installed, so CMSG reed, DMSG or EMSG electronic switches clip onto the stainless barrel and slide to any position along the 45 mm stroke - no special-order piston or retrofit needed.
