Airtac MARU Stainless Steel Mini Cylinder MARU25X110S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X110S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 110mm 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 MARU25X110S
AirTAC rates the 25 mm MAR bore at 245.3 N push and 206.1 N pull at 0.5 MPa - the MARU25X110S turns that into a 110 mm stroke with an up-facing, integrally mounted front flange and double-acting cushioned motion. At 0.7 MPa the push climbs to 343.4 N; theoretical peak 50 kgf.
Construction is a riveted round body: stainless barrel, hard-chrome plated carbon-steel rod, aluminium covers. The variable cushion at both ends matters more as the stroke grows - at 110 mm and speeds toward 800 mm/s, dial the needles in so loads settle instead of slamming the covers. Plan on about 147 N of working force, equivalent to lifting roughly 12 kg vertically with margin. Every MAR ships with the piston magnet already fitted, so CMSG, DMSG or EMSG switches need no special order.

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 MARU25X110S Is Used
Filler head lift
Raises and lowers a small filling nozzle head on a bottling carousel through 110 mm, cushioned so the nozzle does not splash at stroke end.
Bin gate
Opens a gravity-feed bin gate at a warehouse pick station, the integral top mount bolting straight to the bin frame with no extra bracket.
Test-rig press
Applies a 147 N-class proof load to a small sensor housing on an end-of-line test rig, with stroke position reported by an EMSG switch.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X110S the Right Cylinder?
Below this size the 20 mm bore offers 157 N at 0.5 MPa; above it, 32 mm gives 402.2 N and 40 mm reaches 628.3 N. Keep side loads off the 10 mm rod - guide the load externally, since a 110 mm exposure amplifies bending at the M10x1.25 thread. Remember the cylinder is not a brake: with air off, the load can move the piston, so a rod lock handles holding duty. Ports are 1/8", working 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 MARU25X110S FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical maximum at 1.0 MPa is 50 kgf. Rod thread M10x1.25, ports 1/8", operating range 0.15-1.0 MPa (22-145 psi).
The adjustable air cushion at each end decelerates the load over the last few millimetres, so faster cycles or heavier parts arrive gently instead of hammering the covers. Turn the needle screws in or out during commissioning to suit the load.
