Airtac MAC Stainless Steel Mini Air Cylinder MAC50X45SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X45SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 45mm 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 MAC50X45SCA
With a 50 mm barrel pushing 981 N (about 100 kgf) at 0.5 MPa, the MAC50X45SCA sits in the mid-heavy band of AirTAC's cushioned round-body mini range. Double acting throughout - air extends and retracts the rod - with a variable air cushion at each end, so cycle speeds anywhere in the 30-800 mm/s window can be run without hammering the covers. The riveted stainless tube and hard-chrome plated rod (20 um) shake off washdown and damp shop air, an edge painted aluminium minis cannot match.
Keep real work near 589 N of that 981 N rating at 0.5 MPa; on a vertical axis the bore still lifts about 50 kg once the 100 kg theoretical figure is halved for margin. The piston magnet is fitted as standard, letting CMSG, DMSG or EMSG switches clip on for end-of-stroke signals. Air supply spans 0.15-1.0 MPa (22-145 psi).

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 MAC50X45SCA Is Used
Pallet elevator heads
Lifting a 45 kg descender plate on a small conveyor elevator draws about 440 N, well inside the 50 kg vertical figure this bore carries at 0.5 MPa.
Benchtop press dies
Crimping terminal blocks on a assembly jig needs roughly 500 N, so the 981 N push at 0.5 MPa covers it while the end cushion damps the punch-through.
Bottling line gate pushers
The stainless barrel suits washdown zones; swinging bottles through a lane gate at 300 mm/s with the CA pivot eye and cushioned stops at each gate seat.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X45SCA the Right Cylinder?
A 40 mm bore gives 628 N at 0.5 MPa and the 63 mm step-up gives 1558 N, so this 50 mm barrel is the match for 400-600 N of real work. The cushion softens stops but holds nothing: cut the air and the piston settles wherever it was, so a pilot check valve or rod lock keeps a clamp shut. Mount through the CA pivot eye with an SDB bracket, or choose FA flange and LB foot plates; I and Y rod knuckles suit linkage ends. Ports are 1/4", PT thread standard, G and NPT order options; for simple bump-and-return duties the uncushioned MA covers the lighter side of the family.
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 MAC50X45SCA FAQ
At 0.5 MPa it delivers 981 N on extend and 881 N on retract; at 0.7 MPa, 1374 N extend and 1233 N retract; theoretical peak about 200 kgf at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, ports 1/4", rod thread M14x1.5, stroke 45 mm.
No. Every MAC ships with the piston magnet built in as standard equipment, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel - no special-order piston and no retrofit work.
