Airtac MAC Stainless Steel Mini Air Cylinder MAC50X225SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X225SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 225mm 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 MAC50X225SU
A 225 mm stroke on a 50 mm bore gives this flat-end MAC the reach for sliding doors, gates and long push operations, moving them with 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa. It is double acting - air extends and retracts the rod - and both ends carry a variable air cushion you tune with the needle screws to kill end-of-stroke bang.
The U back cover is machined flat, so it bolts flush against fixed surfaces without an adapter. Inside, the riveted stainless barrel and hard-chrome plated rod stand up to humid, dusty or lightly corrosive air far better than painted-steel minis. Every MAC ships with the piston magnet as standard equipment, letting CMSG / DMSG / EMSG switches report stroke position. As a sizing rule, count on about 590 N of working push at 0.5 MPa (six tenths of the rated figure) and match that against your load before ordering.

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 MAC50X225SU Is Used
Slide-door actuator
Driving a 60 kg sliding guard door on a CNC cell enclosure, with the cushion easing the door into its closed stop.
Carton eject pusher
Pushing packed cartons off a case-packer conveyor where a DMSG switch confirms full extension before the next box drops.
Hopper gate control
Opening and closing a powder hopper's slide gate in a humid plant, where the stainless barrel resists condensation.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X225SU the Right Cylinder?
If 981.3 N at 0.5 MPa is more than the job needs, a 40 mm bore (628.3 N) saves space; if the load stalls it, step to the 63 mm bore and its 1557.9 N. Air supply can run from 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi). The U flat-end cover plus an LB foot bracket suits rigid frame mounting, while FA and SDB options cover flanged and pivoted setups. Because a 225 mm rod with no guide can bend under side load, guide the load externally on long travels. Remember the cylinder will drift if supply air is lost - for a held position, add a rod lock or pilot check valve rather than relying on the cushion.
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 MAC50X225SU FAQ
The magnet is built in as standard, so CMSG, DMSG and EMSG switches drop onto the stainless barrel along the full 225 mm stroke with no special piston. For mounting, the U back cover presents a flat machined face for direct bolting, and AirTAC's FA flange, LB foot or SDB pivot bracket can be added. Ports are 1/4 in with PT threads; G or NPT is available.
Bore 50 mm, stroke 225 mm, rod 16 mm with M14x1.5 male thread. Push at 0.5 MPa is 981.3 N, pull 880.8 N; at 0.7 MPa, push is 1373.8 N and pull 1233.1 N; theoretical maximum is 200.1 kgf at 1.0 MPa. Double acting with a variable air cushion at both ends, speed 30-800 mm/s, air filtered to 40 um.
