Airtac MAC Stainless Steel Mini Air Cylinder MAC50X55SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X55SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 55mm 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 MAC50X55SCA
Framed for guards, slides and clamps that need just over 50 mm of throw, the MAC50X55SCA is double acting with a variable air cushion at each end, running on 0.15-1.0 MPa (22-145 psi) filtered air. At 0.5 MPa the 50 mm bore pushes 981 N, enough to clamp aluminium extrusion or seat bushings without upsizing the whole machine frame.
Because the barrel is a rolled stainless tube over a hard-chromed 16 mm rod, splash zones and humid sheds do not chew it up the way painted minis suffer. Expect about 589 N of dependable working force at 0.5 MPa, or roughly 50 kg of vertical lift once the 100 kg theoretical figure is halved for a 2:1 margin, and clip a CMSG, DMSG or EMSG switch straight onto the magnet-equipped piston.

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 MAC50X55SCA Is Used
CNC enclosure guard slide
A 55 mm throw slides a sheet-metal guard just past its latch roller; the CA pivot eye copes with the slight arc of the swing arm.
Nameplate hot-stamp jig
Marking aluminium nameplates draws near 450 N of die pressure, comfortably under the 589 N dependable figure available at 0.5 MPa.
Carton flap tucker
A packaging line folding bottom flaps at 400 mm/s; the adjustable end cushions absorb each tuck without jolting the carton off the belt.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X55SCA the Right Cylinder?
Drop to 40 mm (628 N at 0.5 MPa) for lighter clamps or climb to 63 mm (1558 N) when demand passes 600 N. The rod sits wherever the valve last left it - with air gone it drifts, so a rod lock or pilot check valve handles load holding. The CA pivot eye takes an SDB pivot bracket, while FA flange and LB foot plates suit fixed frames. Ports are 1/4", PT thread standard, and G or NPT are order options.
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 MAC50X55SCA FAQ
Figures at 0.5 MPa: 981 N extend, 881 N retract. At 0.7 MPa: 1374 N extend, 1233 N retract. The theoretical ceiling is 200 kgf at 1.0 MPa, so sizing duty near 60 percent of the 0.5 MPa figure gives a comfortable working margin.
Back both needle screws fully out before start-up, then close them gradually until the stops run smooth. These are adjustable air cushions, not fixed bumpers, so you can trade stroke-end softness against cycle time anywhere in the 30-800 mm/s range.
