Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MAC63X75SCA
A 75 mm stroke gives this 63 mm cushioned cylinder extra reach: 1558 N of push at 0.5 MPa travels farther for ejecting parts or swinging flaps clear of a machine opening. Inside, the stainless barrel and hard-chrome plated rod resist the corrosion that swells painted minis, and the rolled cover joint seals the body reliably.
Needle screws at each end tune the air cushion, so the 75 mm travel can stop a swinging gate softly. Expect about 935 N of usable force at 0.5 MPa - roughly 79 kg lifted vertically at a 2:1 margin - and remember the rod drifts freely when air is off unless a rod lock or pilot check valve is fitted. The magnet is already installed for CMSG / DMSG / EMSG 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 (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 MAC63X75SCA Is Used
Battery bay gate on a forklift charger
A pivot-mounted barrier swings 75 mm clear of the charging bay; 2181 N of push at 0.7 MPa overcomes stiff hinge friction.
Reject pusher on a can line
Knocks off-spec cans sideways at up to 800 mm/s; cushions keep the 75 mm return from rattling the guide rails.
Platen return on a small forming press
Raises a 70 kg platen with margin to spare, and the 1457 N pull side brings it back down under full power.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCA the Right Cylinder?
With a 75 mm stroke on a 16 mm rod, guide the load so side force stays low near full extension; long cantilevers bend the rod and wear the seals. For shorter moves the 50 mm bore (981 N at 0.5 MPa) saves air, and there is no step above 63 mm in this series.
The CA pivot back cover swings with linkages, while FA flange, LB foot and SDB pivot brackets handle fixed frames. Ports are 1/4"; pressure runs 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 MAC63X75SCA FAQ
Push is 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa it reaches 2181.0 N push and 2040.3 N pull, with 317.7 kgf as the theoretical 1.0 MPa peak. The bore is 63 mm, rod 16 mm (M14x1.5), ports 1/4", stroke 75 mm.
Both ends of the 75 mm stroke have adjustable air cushions - open the needle screws fully on commissioning and close them until motion stops cleanly. The piston magnet is standard equipment, so CMSG, DMSG or EMSG switches snap onto the barrel for end-of-stroke signals.
