Airtac MAC Stainless Steel Mini Air Cylinder MAC50X15SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X15SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 15mm 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 MAC50X15SCA
A riveted stainless tube wrapped around aluminium covers gives the MAC50X15SCA a sealed round body that shrugs off damp workshops and mild washdown - a real step up from painted minis in food or outdoor corners. Inside, a hard-chrome plated 16 mm rod rides on two-way seals that store their own grease.
Despite the short 15 mm stroke it is a heavyweight: 981 N push and 881 N pull at 0.5 MPa, scaling to 1374 N at 0.7 MPa. Plan real work at about 589 N so the cylinder is not ridden at its limit. Double acting with a variable air cushion at both ends, it turns 0.15-1.0 MPa (22-145 psi) into crisp clamping anywhere between 30 and 800 mm/s. The CA pivot back cover accepts a clevis-style link directly, and the standard magnet feeds CMSG, DMSG or EMSG switches out of the box.

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 MAC50X15SCA Is Used
Drill jig toggle clamping
Swing the CA pivot through a link to clamp jigs on a radial drilling fixture; 981 N at 0.5 MPa holds steel parts solid through the cut.
Terminal staking press
A 15 mm stroke is ideal for staking or coining terminals in a small bench press, with 1374 N available at 0.7 MPa.
Mold ejection kick
Use the short stroke to kick parts off an injection mold core; the built-in magnet signals ejection complete to the PLC.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X15SCA the Right Cylinder?
Compare forces before committing: the 40 mm bore sibling manages 628 N push at 0.5 MPa, while stepping up to 63 mm buys 1558 N. For a 15 mm clamp stroke this 50 mm bore is usually the sweet spot. Note that a centred valve leaves the piston free to drift - hold a clamped part with a rod lock or pilot check, since the cushion is not a brake. Pivot mounts suit the CA back cover; FA flange, LB foot or SDB brackets cover fixed layouts.
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 MAC50X15SCA FAQ
Push at 0.5 MPa is 981 N with 881 N pull; at 0.7 MPa it reaches 1374 N push and 1233 N pull, and the theoretical ceiling at 1.0 MPa is 200 kgf. Operating band 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, 1/4" ports.
Within reason, yes. The stainless round barrel, hard-chrome plated rod and rolled-on seals resist moisture and mild washdown far better than painted mini cylinders, making it a sensible pick in food, dairy or outdoor installations. Avoid jetting straight at the rod seals.
