Airtac MAC Stainless Steel Mini Air Cylinder MAC50X275SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X275SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 275mm 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 MAC50X275SCA
Swinging, lever and toggle linkages want a pivot, and the MAC50X275SCA ships with exactly that: a CA pivot back cover on a 50 mm double-acting body. Expect 981.3 N of push at 0.5 MPa (880.8 N on retract) across a 275 mm stroke, with a variable air cushion at both ends to tame linkage slam. The riveted stainless barrel and hard-chrome rod keep corrosion out of damp plants and outdoor rigs.
Vertical mounting lifts close to 100 kg against gravity - halve that to about 50 kg for a comfortable 2:1 margin on actual part weights. Design around roughly 589 N of continuous force and the cylinder will run cool and last. A magnet comes built in, letting CMSG, DMSG or EMSG sensors report end positions without any special-order hardware. Speeds 30-800 mm/s; pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 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 MAC50X275SCA Is Used
Swing-arm chute diverters
A pivoting deflector plate on a grain or plastic pellet line swings through 275 mm of arc, driven by 981.3 N at 0.5 MPa.
Toggle clamp fixture actuation
The CA pivot couples straight to a lever linkage on welding jigs, with the air cushion keeping the toggle from hammering home.
Sample carousel indexing
Lab and pharma carousel trays tilt or advance on a 275 mm stroke; the standard magnet feeds a DMSG signal straight to the PLC.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X275SCA the Right Cylinder?
The 275 mm stroke and pivot cover suit swing arms and four-bar linkages; if the job is a straight fixed push, compare the U flat-end back cover, and for heavier duty the 63 mm bore gives 1557.9 N at 0.5 MPa versus 628.3 N from a 40 mm. Long strokes like this deserve alignment attention - a side-loaded 16 mm rod will wear seals early, so guide the load or add a knuckle. When air is vented the rod drifts freely, so use a rod lock or pilot check valve to hold a suspended arm.
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 MAC50X275SCA FAQ
Push is 981.3 N and pull 880.8 N at 0.5 MPa; at 0.7 MPa it reaches 1373.8 N push and 1233.1 N pull. Theoretical ceiling is 200.1 kgf at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
A pivot lets the cylinder follow an arc, so linkages and swing arms are never forced sideways. The body itself is a riveted stainless round barrel with a hard-chrome 16 mm rod and a standard magnet for CMSG / DMSG / EMSG switches - no special piston needed.
