Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 250mm 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 MAC63X250SCA
Long travel with real muscle is the brief for the MAC63X250SCA: 250 mm of stroke on the 63 mm bore, double acting, cushions adjustable at both ends, and a working pressure of 0.15-1.0 MPa (22-145 psi). At 0.5 MPa it pushes 1558 N and pulls 1457 N - enough to close large molds, lift heavy covers or press-fit bushings.
Budget about 935 N of that 0.5 MPa push for the actual job and the machine keeps its margin. Covers and a stainless block are rolled onto the barrel to form a sealed round body that shrugs off hose-down in food plants and salt-laden air outdoors, and the standard-fitted magnet accepts CMSG, DMSG or EMSG switches unchanged. Speed spans 30-800 mm/s.

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 MAC63X250SCA Is Used
Mold cover lift on an injection press
Raises steel top clamps between shots; with a 2:1 margin the rod lifts about 79 kg cleanly over 250 mm.
Press-to-press transfer pusher
Slides large stampings from one press platen to the next; about 935 N of working force does the pushing without shock.
Pallet magazine elevator
Lifts a stack of empty pallets to feed height; the variable cushion settles the load at the top without bounce.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X250SCA the Right Cylinder?
A 50 mm bore manages 981 N at 0.5 MPa - roughly a third less - so downsize only for light loads; 63 mm is the ceiling here, and beyond it you are into multiple cylinders or a bigger series. The CA pivot cover takes an SDB pivot bracket or a direct pin, while FA flange and LB foot options suit rigid frames. Air is the only thing holding position: drop the supply and a raised load falls, so a rod lock or pilot check valve belongs on any lifting axis. At 250 mm of stroke, guide the load externally and keep the thrust aligned to spare the 16 mm rod from bending stress.
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 MAC63X250SCA FAQ
Push at 0.5 MPa is 1558 N with 1457 N on the pull side; at 0.7 MPa the numbers are 2181 N push and 2040 N pull; theoretical peak at 1.0 MPa is 317.7 kgf. Run the cylinder on 0.15-1.0 MPa (22-145 psi), air filtered to 40 um.
Start with the cushions. On first run-up, back both needle screws off, then close them a little at a time until the 250 mm stroke settles quietly at your running speed, anywhere from 30-800 mm/s. The variable air cushion at both ends is what lets you carry heavy loads at speed without hammering the covers.
