Airtac MAC Stainless Steel Mini Air Cylinder MAC50X700SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X700SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 700mm 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 MAC50X700SU
With a flat-end U back cover and a 700 mm stroke built to order, this 50 mm bore MAC doubles as a compact long-reach pusher. It is double acting - air drives the rod out and back - and both ends include a variable air cushion that absorbs end-of-stroke shock when you run fast or heavy. Expect 981.3 N pushing and 880.8 N pulling at 0.5 MPa, rising to 1373.8 N at 0.7 MPa with a 200.1 kgf theoretical maximum at 1.0 MPa.
The riveted stainless round barrel shrugs off splash and humidity, an honest advantage over painted mini cylinders in food and outdoor machinery. Need to halve the theoretical 100 kg vertical lift rating for a 2:1 margin? Count on about 50 kg of real lift, or plan loads around 589 N of usable push. CMSG, DMSG and EMSG reed switches drop straight onto the standard built-in magnet.

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 MAC50X700SU Is Used
Long-slide ejector on an injection press
700 mm of travel clears a deep mould cavity and 981.3 N at 0.5 MPa pushes sprues and finished parts clear of the platen.
Scrap chute gate on a stamping press
1373.8 N at 0.7 MPa swings a heavy scrap gate open and shut, and the flat-end U cover bolts straight onto the press frame.
Hatch pusher on a fish-processing deck
The stainless barrel stands up to salt spray and daily hose-down that would corrode a painted mini cylinder within months.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X700SU the Right Cylinder?
Downsize to a 40 mm bore if 628.3 N at 0.5 MPa covers the job; upsize to the 63 mm bore (1557.9 N) when you need real tonnage. Because the MAC is a plain double-acting cylinder, the rod drifts the moment the valve centres or supply pressure falls - fit a pilot check valve or rod lock when the load has to stay. The U flat-end cover bolts directly to fixed faces; FA flange, LB foot and SDB pivot brackets adapt it to any frame. Rod thread is M14x1.5 male and the port is 1/4 inch, so check your fittings early on a 700 mm run.
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 MAC50X700SU FAQ
Design figures: 981.3 N push and 880.8 N pull at 0.5 MPa, 1373.8 N push and 1233.1 N pull at 0.7 MPa, and a theoretical 200.1 kgf maximum at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi), speeds 30-800 mm/s.
Open both cushion needle screws fully on first run, then close them gradually until end-of-stroke knock fades at your working speed. The magnet is built in as standard, so CMSG, DMSG and EMSG switches clip onto the stainless barrel with no special-order piston.
