Airtac MAC Stainless Steel Mini Air Cylinder MAC50X650SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X650SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm 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 MAC50X650SCA
The 650 mm travel here is a made-to-order stroke - the standard 50 mm range tops out at 500 mm - so AirTAC builds this MAC to order with the CA pivot back cover. Force is unchanged by stroke length: 981.3 N push and 880.8 N pull at 0.5 MPa, 1373.8 N at 0.7 MPa, and 200.1 kgf as the theoretical maximum.
On a long stroke the hard-chrome rod is well exposed, so keep side loads off it and guide the load externally. Double-acting air plus a variable air cushion at both ends still applies, the stainless riveted barrel resists corrosion along its whole length, and the standard magnet lets CMSG / DMSG / EMSG switches signal position anywhere across the 650 mm travel. Treating 100 kg as the vertical-lift ceiling - or 50 kg with a 2:1 margin - helps you match a real payload.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X650SCA Is Used
Lift-gate actuation
The 650 mm made-to-order stroke raises a light access hatch on a food-line frame, the CA pivot eye tracking the lid arc as it opens.
Battery bay door pusher
Long-travel MAC pushes heavy battery cabinets along rails in a warehouse charging bay, guided externally to protect the exposed rod.
Textile roll ejector
Full-width fabric rolls are nudged off a winding station by the extended 650 mm travel, position flagged by DMSG switches at both ends.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X650SCA the Right Cylinder?
Compare 981.3 N push at 0.5 MPa against the 40 mm bore at 628.3 N and the 63 mm bore at 1557.9 N to confirm the 50 mm class is right. Since the piston cannot hold position without air - a centred valve lets the load drift - a rod lock or pilot check valve is the answer where holding matters. A 650 mm rod swinging on the CA pivot eye needs external guiding and low side load, and the non-standard stroke is ordered through AirTAC with PT, G or NPT ports to suit.
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 MAC50X650SCA FAQ
Stroke does not change force: 981.3 N push and 880.8 N pull at 0.5 MPa, 1373.8 N and 1233.1 N at 0.7 MPa, 200.1 kgf theoretical at 1.0 MPa. It is double acting with variable cushion, 0.15-1.0 MPa (22-145 psi) working pressure, 1.5 MPa (215 psi) proof, 30-800 mm/s.
Standard 50 mm strokes stop at 500 mm, so 650 mm is a non-standard build. AirTAC supplies it with the CA pivot cover, 1/4" ports, a 16 mm hard-chrome rod and M14x1.5 rod thread, plus the standard magnet for CMSG / DMSG / EMSG switches.
