Airtac MARU Stainless Steel Mini Cylinder MARU25X360S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X360S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 360mm 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 MARU25X360S
Inside the MARU25X360S is a riveted stainless-steel round barrel and a hard-chrome plated 10 mm carbon-steel rod, a combination that shrugs off washdown and humid plant air far better than painted mini cylinders. Air drives the piston both ways - double acting - and a variable cushion at each end lets you tune out end-of-stroke shock when running up to 800 mm/s.
The 25 mm bore delivers 245 N of push and 206 N of pull at 0.5 MPa, rising to 343 N of push at 0.7 MPa. In practice, size the task at roughly 147 N so seals and service life stay generous; theoretically the same bore is worth about 25 kgf at 1.0 MPa, which translates to lifting around 12 kg vertically with a 2:1 margin. The integrated top bracket means the cylinder bolts straight to the machine frame - no separate foot to 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 MARU25X360S Is Used
Carton flap folding on a wrap-around case packer
The 360 mm stroke sweeps tall flaps closed while the 245 N push at 0.5 MPa seats them squarely ahead of the taping head.
Sorting-station pusher on a roller conveyor
Mounted under the line, the cylinder kicks totes off a 600 mm lane, and the 206 N pull retracts the blade quickly between boxes.
Reject gate on a bottling line
The variable cushion stops the gate slamming as the diverter actuates under a filling head, with rod speed settings up to 800 mm/s available.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X360S the Right Cylinder?
At 360 mm this is a long stroke for a 25 mm bore, so keep side load off the 10 mm rod - guide the workpiece externally or the rod will bend before the seals complain. If 245 N of push at 0.5 MPa is more than you need, the 20 mm bore MAR at 157 N is the lighter choice; if it is not enough, the 32 mm bore pushes 402 N at the same pressure. One more caveat: with air removed the rod simply drifts with the load, so add a rod lock where the position must hold.
The built-in magnet is standard equipment, so CMSG, DMSG or EMSG switches mount on the barrel without a special piston. The U suffix means the front cover carries a top-mount bracket; rod knuckles I and Y still fit the M10x1.25 male 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 MARU25X360S FAQ
At 0.5 MPa the 25 mm bore pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N and pull to 288.5 N. Theoretical maximum is 50.0 kgf at 1.0 MPa. Port size is 1/8 inch and the rod thread is M10x1.25.
The barrel is stainless steel and the rod is hard-chrome plated carbon steel, so mild corrosion and routine washdown are handled well - a real advantage over painted-steel mini cylinders. Operating range is -20 to +70 C with air filtered to 40 um.
