Airtac MARU Stainless Steel Mini Cylinder MARU50X500S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X500S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MARU Stainless Steel Mini Cylinder MARU50X500S
Five hundred millimetres is the longest catalog stroke for a 50 mm MAR, and the MARU50X500S uses it fully: 981.3 N of push and 880.8 N of pull at 0.5 MPa, or 1373.8 N of push when the line runs at 0.7 MPa. Both stroke ends carry a variable air cushion, adjustable with needle screws so the covers never take a hammering even at 800 mm/s.
Around that stroke sits a round riveted barrel - stainless tube, aluminium covers, a 16 mm carbon-steel rod plated with 20 um of hard chrome - a combination that laughs at splash, humidity and outdoor dust. The up mount is integral, rolled into the front cover during assembly. In lift terms the bore develops about 100 kg of vertical thrust at 0.5 MPa; budget for 50 kg and you keep a 2:1 margin against friction and pressure sag.

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 MARU Stainless Steel Mini Cylinder MARU50X500S Is Used
Case packer pusher
Sweeps a full layer of pouches 500 mm into a corrugated case at a packaging station, cushioning both stops to keep the layer square.
Pallet ejector off a stretch wrapper
Ejects wrapped pallets off the turntable onto a takeaway conveyor across the full 500 mm travel.
Bottling-line diverter gate
Kicks single-file bottles onto a side lane at a filler discharge; 880.8 N of pull resets the gate briskly between batches.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X500S the Right Cylinder?
A 40 mm MAR saves space below 628.3 N of push at 0.5 MPa; beyond about 1000 N, the 63 mm bore and its 1557.9 N take over. Over 500 mm of unsupported travel, guide the load externally - a 16 mm rod tolerates little side load at full extension.
When air pressure fails the rod simply moves with whatever pushes it, so add a rod lock for parked loads. Sensor ready: the magnet comes standard and suits CMSG, DMSG and EMSG switches.
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 MARU Stainless Steel Mini Cylinder MARU50X500S FAQ
Rated 981.3 N push and 880.8 N pull at 0.5 MPa, rising to 1373.8 N push and 1233.1 N pull at 0.7 MPa, with 200.1 kgf as the theoretical ceiling at 1.0 MPa. Operating band is 0.15-1.0 MPa (22-145 psi), proof tested at 1.5 MPa (215 psi).
The barrel is stainless steel and the 16 mm rod carries 20 um of hard chrome, so mild washdown, humidity and outdoor exposure are handled far better than by painted-steel minis. Ports are 1/4 inch on this bore, air should be filtered to 40 um, and the temperature range is -20 to +70 C.
