Airtac MAC Stainless Steel Mini Air Cylinder MAC63X42SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X42SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 42mm 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 MAC63X42SCA
Where a clamp arm needs real muscle over a short arc, the MAC63X42SCA puts 1557.9 N of push and 1457.4 N of pull at 0.5 MPa behind 42 mm of travel. The barrel is stainless steel rolled into a riveted round body, so coolant mist and cutting-fluid splash in a machine shop do not attack it the way they ruin painted minis.
Because this bore tops the MAC range, the practical ceiling is high: keep design load near 935 N and pressure dips will never stall the clamp. In raw vertical terms the same force equals about 159 kg, or 79 kg once a 2:1 margin is applied. The CA pivot back cover lets the body swing with the clamp linkage, and the built-in magnet - standard, not an option - accepts CMSG / DMSG / EMSG switches for end-of-stroke proof.

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 MAC63X42SCA Is Used
Fixture locate pin
Raises a diamond-shaped locate pin in a CNC machining fixture, with the pivot cover absorbing the small arc of the lifting linkage.
Carton head press
Drives the top-press head on a case-packing machine, cushioning each 42 mm downstroke so cartons are not crushed at the stops.
Pallet stop clamp
Snaps a swing stop into place on an aggregate-plant pallet line, where the stainless barrel survives dust washdowns year after year.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X42SCA the Right Cylinder?
If the job needs under 590 N of usable force, bore 50 (981.3 N at 0.5 MPa) will do it on less air; no MAC bore exists above 63. The CA pivot cover pairs naturally with SDB pivot brackets, while FA flange and LB foot hardware cover fixed-frame cases. Remember that with the valve centred or air off, the piston drifts freely - for a clamp that must stay shut during an e-stop, spec a rod lock or pilot check valve alongside.
A 42 mm stroke tolerates modest misalignment through the pivot, but keep the push axis square to the work and cushion screws open for the first run; speed range is 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
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 MAC63X42SCA FAQ
At 0.5 MPa it delivers 1557.9 N push and 1457.4 N pull; at 0.7 MPa, 2181.0 N push and 2040.3 N pull. Theoretical maximum force at 1.0 MPa is 317.7 kgf. Ports are 1/4 inch and the rod thread is M14x1.5; operating range is 0.15-1.0 MPa (22-145 psi).
Yes - the piston magnet is built in as standard on every MAC cylinder, so CMSG, DMSG or EMSG switches clamp directly onto the barrel body. No special-order piston, no drilled brackets; snap the switch on and wire it to a PLC input.
