Airtac MAC Stainless Steel Mini Air Cylinder MAC63X145SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X145SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 145mm 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 MAC63X145SCA
The top bore of AirTAC's round-body MA family, MAC63X145SCA turns 0.5 MPa (73 psi) into 1558 N of push and 1457 N of pull across a 145 mm stroke. Double acting by design, it cushions with variable air at both ends so the rod decelerates a moving load gently instead of hammering the covers.
Its riveted build - aluminium-alloy covers and a stainless block rolled onto a stainless tube - stays sealed under vibration, and the hard-chromed 16 mm rod resists scoring in dirty air. The CA back cover carries an integral pivot eye for linkage mounts, and the built-in magnet lets CMSG / DMSG / EMSG switches sit anywhere on the barrel. When planning loads, count on roughly 935 N of usable push at 0.5 MPa; that is about 79 kg of vertical lift with a 2:1 margin.

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 MAC63X145SCA Is Used
Tipper latch on a foundry sand hopper
A swinging linkage that latches and releases a hopper gate, where the CA pivot eye bolts straight to the mechanism and the cushion eases the gate slam.
Roll-clamp assist on a material-handling arm
Actuating a clamp arm that grips cartons at 145 mm reach, with an EMSG switch reporting grip position back to the PLC.
Mix-vessel scraper drive in a coatings lab
Moving a scraper blade across a 145 mm arc inside a paint test mixer, where the stainless barrel stands up to repeated solvent splashes.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X145SCA the Right Cylinder?
Compare by force: a 50 mm bore gives 981 N at 0.5 MPa, while this 63 mm bore reaches 1558 N and 2181 N at 0.7 MPa - the largest the series offers. If the load must stay clamped when air drops, add a rod lock or pilot check valve, because a standard double-acting cylinder drifts once supply pressure is gone. The CA pivot eye suits swinging linkages and hopper gates; for rigid fixing choose the FA flange or LB foot options instead, or an SDB pivot bracket. At 145 mm of travel the 16 mm rod is best kept in compression or externally guided to avoid side-load wear.
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 MAC63X145SCA FAQ
1558 N push and 1457 N pull at 0.5 MPa; 2181 N push and 2040 N pull at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Air pressure spans 0.15-1.0 MPa (22-145 psi), speed runs 30-800 mm/s, and the bore's 1/4" ports take standard fittings.
Back both needle screws fully off, run the cylinder slowly, then close them gradually until the 145 mm stroke decelerates smoothly at each end. The cushion is variable, not a fixed bumper, so it can be retuned when speed or load changes - but it is not a brake and will not hold the rod against gravity if air is lost.
