Airtac MAC Stainless Steel Mini Air Cylinder MAC63X20SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X20SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 20mm stroke, 1/4" 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 MAC63X20SCA
A 20 mm stroke with a 63 mm bore makes MAC63X20SCA a short-hit specialist: it delivers 1557.9 N of push at 0.5 MPa in barely 20 mm of travel, ideal where clamping points are tight but force is not negotiable. The double-acting design feeds air to both chambers, while variable cushions at each end trim the impact of fast, heavy hits. Its stainless barrel and hard-chrome plated rod take washdown and damp plant air in stride, outlasting painted mini cylinders in food and chemical areas.
The CA pivot back cover lets the cylinder swing as the load path changes - handy on toggle clamps and linkage-driven fixtures. A magnet is part of the standard build, so CMSG, DMSG or EMSG switches bolt straight on to confirm clamp state. Keep a reserve under the 1557.9 N rating for dependable work: about 935 N at 0.5 MPa is a realistic planning figure.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MAC63X20SCA Is Used
Clamp nests on tube-bending fixtures
The short 20 mm pinch is all a swing clamp needs; 1558 N at 0.5 MPa holds tube stock against the form die through the bend.
Eject pins on stamping benches
Knocks finished stampings out of shallow dies with a quick 20 mm kick; the variable cushion keeps the pin from battering the die face.
Reject gate on a filling line
Flicks a diverter flap to push off-code bottles off the conveyor; the stainless body handles the wet, sugary splash zone that corrodes painted minis.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X20SCA the Right Cylinder?
For a 20 mm hit with less force, the 50 mm bore version pushes 981.3 N at 0.5 MPa; nothing in the MAC line exceeds 63 mm. If the clamp must stay shut through an E-stop or air failure, remember this cylinder cannot hold itself - the cushions decelerate travel, they do not lock - so spec a rod lock or pilot check valve. The CA pivot cover handles swinging mounts directly, with SDB pivot bracket, FA flange and LB foot as alternates; I and Y knuckles suit the rod end.
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 MAC63X20SCA FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa, 2181 N push and 2040.3 N pull; theoretical maximum 317.7 kgf at 1.0 MPa. Bore 63 mm with a 16 mm rod, 1/4" ports, M14x1.5 rod thread, working pressure 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The CA back cover carries an integral pivot, so the cylinder can articulate with toggle links and swing clamps without extra bracketry. Cushion needles at both ends are adjustable - open them fully at commissioning, then close until the 20 mm hit lands quietly. Feed the cylinder air filtered to 40 um for long seal life.
