Airtac MAC Stainless Steel Mini Air Cylinder MAC63X650SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X650SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 650mm 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 MAC63X650SCA
Six hundred fifty millimetres of stroke on a 63 mm bore puts the MAC63X650SCA in made-to-order territory, since the MA standard list ends at 500 mm. The finished cylinder is double acting with a variable cushion at both ends, good for 1557.9 N push and 1457.4 N pull at 0.5 MPa and 2181.0 N extend at 0.7 MPa.
Construction is the reason to pick this over a fabricated slide: a riveted stainless round barrel and hard-chrome plated rod take washdown, dust and outdoor exposure without paint flaking into the mechanism. In practice that means about 935 N of dependable working push at 0.5 MPa and roughly 79 kg of vertical lift at a 2:1 safety margin. The standard-fit magnet pairs with CMSG, DMSG or EMSG switches for position feedback.

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 MAC63X650SCA Is Used
Palletizer case ejector
A 650 mm sweep clears a full layer of cartons off the palletizer table, using about 935 N of working push at 0.5 MPa.
Conveyor take-up tensioner
The cylinder feeds steady tension into a long gravity take-up arm, with the cushion smoothing the last millimetres at each end.
Bake oven rack extractor
Long 650 mm travel pulls hot racks out of a tunnel oven in one stroke, and the stainless barrel handles the humid heat.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X650SCA the Right Cylinder?
One step down, the 40 mm bore manages only 628.3 N push at 0.5 MPa, so anything moving past about 377 N of working load belongs on this 63 mm barrel. Like every unbalanced double acting cylinder it slides freely the instant air is cut, so plan a pilot check valve or a hard stop wherever the load could roll or fall. Fit the CA pivot back cover to a clevis for alignment, or choose FA flange, LB foot and SDB pivot brackets instead; I and Y rod knuckles keep the load from twisting the M14x1.5 rod. Keep external guides under any long-stroke load.
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 MAC63X650SCA FAQ
Extend: 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa. Retract: 1457.4 N at 0.5 MPa and 2040.3 N at 0.7 MPa. Ceiling is 317.7 kgf theoretical at 1.0 MPa. The 650 mm stroke is a custom build, ports are 1/4 inch, air is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
Back both cushion needle screws fully off before the first stroke, then close them gradually until end-of-stroke impact disappears at your working speed. Anywhere in the 30-800 mm/s band the cushion keeps the covers safe, and it never acts as a lock - the piston still moves if air is lost.
