Airtac MARU Stainless Steel Mini Cylinder MARU32X523S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X523S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 523mm stroke, 1/8" 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 MARU32X523S
Built to order with a 523 mm stroke, this bore 32 MAR pushes 402.2 N and pulls 345.6 N at 0.5 MPa - a class that also reaches 563.0 N at 0.7 MPa and 82 kgf theoretical at 1.0 MPa (145 psi). Double acting throughout, with variable air cushions tuned at each head and an upward-facing bracket formed into the front cover.
At roughly 241 N of practical working force, plan on about 20 kg of vertical lift with margin to spare. The 523 mm travel exceeds the 500 mm standard for this bore, and over that span the 12 mm rod needs external guidance if the load hangs off-axis. The piston magnet comes as standard, so CMSG sensors drop straight onto the barrel.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MARU32X523S Is Used
Web Guide on a Slitter Rewinder
523 mm of travel slews a guiding arm to steer film web, with the variable cushions settling each correction without overshoot.
Bin Pusher in Deep Shelving
Ejects tote bins from deep shelf pockets along a 500-plus mm path, the standard magnet signalling home and extended.
Test Rig Actuator
Long, slow strokes load cable samples in a bend-test bench at controlled pressure, cushioned at both ends of the cycle.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X523S the Right Cylinder?
If 402.2 N at 0.5 MPa is more than the job needs, a 25 mm bore (245.3 N) shortens the reach; a 40 mm bore (628.3 N) adds headroom for friction-heavy slides. Long strokes amplify any side load, so support the tooling separately and keep the rod axial. Air loss means drift - no standard MA cylinder holds a mid-stroke position on its own, so fit a rod lock where a stopped position must stay put.
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 MARU32X523S FAQ
Force figures: 402.2 N push and 345.6 N pull at 0.5 MPa, rising to 563.0 N push and 483.8 N pull at 0.7 MPa, with 82 kgf theoretical maximum at 1.0 MPa (145 psi). Supply pressure spans 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the 523 mm stroke is manufactured to order beyond the 500 mm standard.
No. The MAR rolls its own front bracket into the front cover - upward facing on this U-version - so the cylinder bolts directly to the machine plate and separate flange or foot accessories are unnecessary for the series. I and Y rod knuckles still thread onto the M10x1.25 rod end.
