Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MAC63X50SCM
Pin it through the round-end CM back cover and this 50 mm stroke cylinder swings on a pivot while pushing 1557.9 N at 0.5 MPa (1457.4 N on retract), rising to 2181.0 N / 2040.3 N at 0.7 MPa. Double acting and cushioned at both ends, it stays gentle on tooling even at the top of the 30-800 mm/s range. Theoretical peak output is 317.7 kgf at 1.0 MPa, but sizing the application around 935 N of real work keeps it reliable year after year.
Inside the riveted stainless barrel sits a 20 um hard-chrome plated rod that shrugs off coolants and outdoor weather - a genuine edge over painted mini cylinders near washdown lines. The magnet is built in as standard equipment, so CMSG / DMSG / EMSG switches mount on the barrel without ordering options. The 50 mm stroke is a standard catalogue length; air enters through 1/4" ports at 0.15-1.0 MPa (22-145 psi), with 1.5 MPa (215 psi) proof pressure.

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 MAC63X50SCM Is Used
Dairy vat tilt latch
Pivoting a latch that tips a 300 litre mixing vat for drain-down; the round-end cover takes the pivot pin directly and 1557.9 N at 0.5 MPa swings the loaded vat.
Carton divert kicker
Kicking cartons off a sorting line into a strapping lane, where about 935 N of usable push at 0.5 MPa and a 50 mm stroke suit a fast diverter arm.
Press part-present stop
A pivoting stop catching sheet metal parts at a press outfeed, with a DMSG switch confirming the stop is up before the press is allowed to cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCM the Right Cylinder?
For the same 50 mm stroke, the 50 mm bore manages 981.3 N push at 0.5 MPa, so step down if under about 1000 N is enough; there is no step up from 63 mm inside the MAC series. A dropped air signal lets the piston drift rather than holding its place - a rod lock or pilot check valve is the answer where position must persist. The CM round-end cover suits SDB pivot mounting, while FA flange and LB foot brackets handle rigid frames, and I / Y rod knuckles protect the 16 mm rod on linkage duty. The standard magnet supports CMSG / DMSG / EMSG switch feedback without any special-order piston.
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 MAC63X50SCM FAQ
Expect 1557.9 N push and 1457.4 N pull at 0.5 MPa, 2181.0 N push and 2040.3 N pull at 0.7 MPa, and a theoretical peak of 317.7 kgf at 1.0 MPa. The cylinder is double acting with variable air cushions at both ends, runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air, is proof tested at 1.5 MPa (215 psi), and uses 1/4" ports.
Yes - the CM round-end back cover accepts a pivot pin directly, and the SDB pivot bracket, FA flange or LB foot can be added for rigid frames. The built-in magnet is standard equipment, so CMSG / DMSG / EMSG switches bolt onto the barrel with no special-order piston needed.
