Airtac MARU Stainless Steel Mini Cylinder MARU25X30S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X30S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MARU25X30S
Short, punchy and limited to 30 mm of travel - that is the job of the MARU25X30S, a 25 mm bore round-body cylinder in AirTAC's MA family. Double acting with variable cushions at each end, it bolts to the machine through its integrated up-mount bracket; no add-on foot is required. Expect 245 N of push and 206 N of pull at 0.5 MPa, rising to 343 N if you feed it 0.7 MPa.
For clamping a small bracket or ejecting a part from a fixture, halve the rating and you get about 12 kg of vertical lift capacity with a sensible 2:1 margin. The riveted stainless barrel plus the hard-chrome carbon-steel rod (plated to 20 um) resist mild corrosion far better than painted housings, and the grease-storing two-way piston seal keeps friction low stroke after stroke. The magnet is standard, ready for CMSG / DMSG / EMSG position sensing.

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 MARU25X30S Is Used
Bracket clamping in small welding jigs
A 30 mm pinch holds an aluminium trim strip against the jig stop with about 245 N at 0.5 MPa, releasing fast for the next 15 s weld cycle.
Part ejection from mold fixtures
Short 30 mm travel is enough to kick a molded bushing out of the fixture pocket, and the pull side still carries 206 N for a crisp return.
Print-head lift on a coding machine
Raises a CIJ print head 30 mm onto the product, with the equivalent 12 kg safe lift covering the head assembly and a CMSG switch confirming up position.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X30S the Right Cylinder?
With only 30 mm of travel, cycle time matters more than reach: this unit can stroke at up to 800 mm/s, so the whole move finishes in a fraction of a second. Compare bores - a 20 mm cylinder offers 157 N at 0.5 MPa and a 32 mm unit reaches 402 N; the 25 mm sits at 245 N, which suits light clamping well. No position holding on air loss with a standard MAR, so specify a rod lock if the part must stay clamped when pressure drops. The up-mount bracket and standard magnet keep the parts list short, pairing with CMSG / DMSG / 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 MARU25X30S FAQ
Push is 245 N at 0.5 MPa and 343 N at 0.7 MPa; pull is 206 N at 0.5 MPa and 289 N at 0.7 MPa; theoretical maximum is 50 kgf at 1.0 MPa. The bore is 25 mm, stroke 30 mm, rod 10 mm with M10x1.25 thread, ports 1/8", and the working pressure band is 0.15-1.0 MPa (22-145 psi).
The barrel is high-precision stainless steel with the aluminium covers riveted on, and the 10 mm carbon-steel rod carries 20 um of hard chrome. That combination shrugs off mist and mild washdown that pit painted mini cylinders, while the grease-storing two-way piston seal keeps the 30 mm stroke smooth between services.
