Airtac MAC Stainless Steel Mini Air Cylinder MAC63X490SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X490SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 490mm 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 MAC63X490SCA
Close to the 500 mm limit of the bore 63 frame, the MAC63X490SCA swings through 490 mm on a CA pivot back cover built for rotating linkages. It is double acting, so air drives the rod both out and back, and a variable cushion at each end lets you tune the landing at full extension and retraction. Push is 1557.9 N at 0.5 MPa, rising to 2181.0 N at 0.7 MPa.
That cushion matters at this stroke: with about 935 N of dependable push at 0.5 MPa, or roughly 79 kg of vertical lift on a 2:1 margin, dialling the needle screws down keeps the 490 mm touchdown from hammering the pivot pin. The stainless barrel also shrugs off splash-zone corrosion that ruins painted mini bodies.

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 MAC63X490SCA Is Used
Rotating conveyor gate diverter
A 490 mm swing arm diverting totes between two conveyor lanes pins straight into the CA pivot lugs; cushions stop the gate without slam at either lane position.
Boat hatch actuator in a salt-spray yard
Marine splash and salt fog destroy painted minis; the stainless MAC opens a 60 kg equipment hatch through 490 mm while staying well inside its 79 kg vertical lift margin.
Baler lid clamp on a textile baler
Clamping waste fabric bales needs a long sweep; 1557.9 N at 0.5 MPa seats the lid and the variable cushion eases it home instead of hammering the hinge.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X490SCA the Right Cylinder?
Bore 50 offers 981.3 N at 0.5 MPa if your load sits half this class below; bore 63 is the ceiling of the MAC line. The CA cover's pivot lugs accept a clevis or eye pin directly, and LB foot or FA flange parts bolt on for fixed frames. Since the piston has no internal lock, a centred or de-energised valve lets the 490 mm column fall - add a pilot check valve on the cap-side port to hold it in place. On a stroke this long, guide the load linearly; the 16 mm rod tolerates little side load at full extension.
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 MAC63X490SCA FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, 1/4" port, M14x1.5 rod thread, -20 to +70 C.
Back both cushion needle screws fully off at first run, then close them gradually until the 490 mm stroke lands without bounce. For sensing, the piston magnet is already fitted - CMSG, DMSG or EMSG switches clip onto the barrel at any position along the 490 mm travel.
