Airtac MAC Stainless Steel Mini Air Cylinder MAC50X420SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X420SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 420mm 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 MAC50X420SU
A 50 mm bore with 420 mm of cushioned, double-acting travel, the MAC50X420SU is the stainless round-body mini for long slides in wet or dusty plants. Push force at 0.5 MPa is 981.3 N and pull 880.8 N - in daily practice budget roughly 589 N for useful work and the seals will thank you with a long service life. Bores 16 to 63 mm share the same riveted construction, so scaling up or down later stays simple.
Where painted mini cylinders flake and seize, the stainless tube and hard-chrome plated rod shrug off splash, steam and washdown chemicals. The needle-screw air cushion at each end is fully adjustable - back it off before first run, then close it gradually until the 420 mm move stops crisply at up to 800 mm/s. A magnet is built in as standard for CMSG, DMSG or EMSG position switches.

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 MAC50X420SU Is Used
Screen wiper
Drives a scraper blade across a wastewater bar screen, the stainless barrel tolerating constant splash and grit.
Vat hood lift
Raises the inspection hood on a 500 L mixing vat, lifting its 50 kg lid with a 2:1 margin to spare.
Tray indexer
Steps racks of cassettes along a cleanroom conveyor, cushioned stops protecting the carriers from end-of-stroke shock.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X420SU the Right Cylinder?
Force ladder at 0.5 MPa: 628.3 N for the 40 mm bore, 981.3 N here, 1557.9 N for the 63 mm bore - pick the smallest that clears your load with margin. The MAC holds no position on lost air; the piston simply coasts, so a rod lock or pilot check valve is the fix for a load that must hang. Mount the long 420 mm body with an FA flange or LB foot at the U flat-end cover, and order G or NPT threads instead of PT if your valves call for them.
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 MAC50X420SU FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. Operating window is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, fluid air filtered to 40 um.
The rolled stainless tube and 20 um hard-chrome plated rod resist corrosion in washdown, steam and outdoor duty where coated bodies blister. The two-way piston seals also store grease, stretching service intervals on a 420 mm stroke.
