Airtac MARU Stainless Steel Mini Cylinder MARU25X90S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X90S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 90mm 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 MARU25X90S
At 0.5 MPa the 25 mm MARU25X90S pushes 245 N and pulls 206 N along a 90 mm stroke, with variable cushions damping each end of travel. Its up-facing bracket is rolled into the front cover as part of the body itself.
For real-world sizing, count on roughly 147 N of continuous work at 0.5 MPa - enough to lift about 12 kg vertically with a 2:1 margin. The stainless round barrel plus hard-chrome rod tolerates washdown corners where aluminium minis pit, and the factory-fitted magnet means CMSG / DMSG / EMSG switches need no special order.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MARU25X90S Is Used
Die lube spray lift
Raising a spray nozzle into a stamping die zone, the 90 mm stroke clearing the tooling stack between cycles.
Bin fill gate
Feeding swarf and scrap into a bin via a slide gate under a CNC, the magnet switch confirming open and closed.
Test-rig load pad
Applying a set preload to parts on a leak-test rig, alternating between 245 N push and 206 N pull each cycle.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X90S the Right Cylinder?
Bracket-to-bracket, the choice runs 20 mm (157 N) below and 32 mm (402 N) above this 25 mm size at 0.5 MPa - the mid step suits loads in the 150-240 N band. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s. Position holding is not built in: without air the piston drifts freely, so a rod lock is the answer where the load must stay extended. Mounting needs nothing extra because the up bracket is integral, and I / Y knuckles still fit the M10x1.25 rod thread.
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 MARU25X90S FAQ
At 0.5 MPa: 245 N extend, 206 N retract. At 0.7 MPa: 343 N extend, 288 N retract. Theoretical maximum 50 kgf at 1.0 MPa. Verify against a 0.15-1.0 MPa (22-145 psi) supply filtered to 40 um.
No. Variable cushions with needle screws sit at both stroke ends - adjust them on first run - and the up bracket is integral to the riveted front cover, so no separate flange or foot accessory is ordered alongside the cylinder.
