Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 125mm 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 MAC50X125SU
Rated at 981 N push and 881 N pull on 0.5 MPa air, the MAC50X125SU brings the cushioned 50 mm MAC platform to the U flat-end back cover - a plain squared face that fixes flush against machine walls without brackets. Double acting throughout, with variable air cushions at both ends to temper the stop, it runs 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply, and 0.7 MPa lifts push to 1374 N.
Construction is a riveted stainless barrel with hard-chrome plated rod, the pairing that keeps its surface intact where painted steel minis bubble and flake in washdown corners. Against the 981 N rating, a sensible working figure is about 588 N at 0.5 MPa; vertically that same push would carry a 100 kg mass, halved to a 50 kg lift with margin. The standard-fit magnet means CMSG / DMSG / EMSG switches attach as a bolt-on, no special piston build required.

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 MAC50X125SU Is Used
Fixture hold-down
The U flat end bolts flush to a milling fixture plate, applying a 588 N-class clamp on steel brackets throughout the machining cycle.
Battery change latch
Releases a warehouse forklift battery roller latch, the flat back cover seating directly against the counterweight face with no bracketry.
Bottle ejection paddle
On a bottling line, the cushioned 125 mm stroke kicks rejected bottles off the rail without cracking PET at line speed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X125SU the Right Cylinder?
Forces bracket the choice neatly: the 40 mm bore manages 628 N push at 0.5 MPa and the 63 mm bore 1558 N, so the 981 N of this 50 mm unit suits jobs in between. When the supply fails or the valve sits mid-travel, the rod will simply drift - pair a pilot check or rod lock with any suspended load. The U flat-end sits flush on a plate; combine with FA flange, LB foot or SDB pivot brackets plus magnet-based CMSG switching for a complete axis. Ports are 1/4 on all 50 mm MAC cylinders.
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 MAC50X125SU FAQ
Push force is 981 N and pull force 881 N at 0.5 MPa; at 0.7 MPa the MAC50X125SU reaches 1374 N push and 1233 N pull, with a 200 kgf theoretical ceiling. Working pressure 0.15-1.0 MPa (22-145 psi), temperature -20 to +70 C, speed 30-800 mm/s.
No - every MAC ships with the piston magnet fitted as standard, so CMSG, DMSG and EMSG reed switches mount directly for position feedback. No special-order piston or retrofit is involved; the switches simply clip to the barrel.
