Airtac MARU Stainless Steel Mini Cylinder MARU25X10S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X10S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MARU25X10S
Short travel, full force: the MARU25X10S gives just 10 mm of stroke but still delivers the 25 mm bore's 245.3 N push and 206.1 N pull at 0.5 MPa, rising to 343.4 N at 0.7 MPa and 50 kgf theoretical at 1.0 MPa. It is double acting with a variable cushion at both ends and a built-in top (U) mount.
Ten millimetres is enough for clamps, kickers and part-present flags where a long rod would be wasted. The magnet comes standard, so position feedback via CMSG, DMSG or EMSG switches works even on this tiny stroke. With about 147 N of practical force at 0.5 MPa, treat it as a 12 kg vertical lifter with a 2:1 margin. The stainless round barrel and hard-chrome plated rod keep corrosion out of washdown areas.

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 MARU25X10S Is Used
Drill-jig clamp
Clamps a bushing plate in a drilling jig with a 10 mm squeeze, freeing the operator's hands for part loading on every cycle.
Part kicker
Flicks a small machined part off a nest into a chute at end of cycle, the short stroke keeping overall cycle time low.
Photo-eye flag
Pushes a flag in front of a photo-eye to confirm part presence, with a DMSG switch reporting the cylinder's own position too.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X10S the Right Cylinder?
When 157 N from a 20 mm bore is not enough but 402.2 N from a 32 mm bore is overkill, this is the size to pick. A loss of air lets the piston drift - the cushion only softens stroke ends, it does not lock, so specify a rod lock if the clamp must stay closed on failure. Adjust the cushion needles on first run even though the travel is short, and note the mounting is already on the cylinder, no FA, LB or SDB accessory applies. Ports 1/8", pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
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 MARU25X10S FAQ
Yes. Push 245.3 N, pull 206.1 N at 0.5 MPa; at 0.7 MPa, 343.4 N and 288.5 N; theoretical maximum 50 kgf. Stroke length does not change force - only the 10 mm travel is short, while 1/8" ports and the M10x1.25 rod thread stay standard.
Via the up-facing (U) bracket formed on the front cover - it is part of the cylinder, so machine builders just add two screws. No separate foot or flange is used on MAR bodies.
