Airtac MARU Stainless Steel Mini Cylinder MARU25X160S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X160S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MARU25X160S
Twenty-five millimetres of bore on a stainless rolled tube: the MARU25X160S gives 245 N of push and 206 N of pull at 0.5 MPa (343 N at 0.7 MPa) over a 160 mm stroke. Double acting with adjustable air cushions at each end, and the top bracket rolled into the front cover means no loose flange to buy.
Because the barrel is stainless and the 10 mm rod is hard-chrome plated, humid or washed-down surroundings do not chew it up like painted bodies. In practice count on about 147 N of usable push, enough to lift roughly 12 kg vertically against a 2:1 margin. The standard piston magnet accepts CMSG / DMSG / EMSG switches for end-of-stroke signalling.

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 MARU25X160S Is Used
Lift-gate assist on tote elevators
Raise lightweight tote gates 160 mm between conveyor levels; 245 N at 0.5 MPa handles plastic totes with margin to spare.
Sample tray indexer
Advance a 12-position sample tray one station per cycle in a lab autosampler; the stainless body wipes clean between runs.
Carton flap tucker
Fold tall flaps down on a packaging machine; the cushion absorbs the snap at stroke end so flaps seat without bounce.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X160S the Right Cylinder?
This 160 mm travel sits between the compact 50 mm builds and the full 500 mm versions, all with the same 245 N class output. Compare: a 20 mm MAR manages 157 N at 0.5 MPa, a 32 mm bore 402 N. Long travel plus side load will bend a 10 mm rod, so guide the payload externally. If the rod must stay put on air failure, fit a rod lock. The piston magnet is standard - pick CMSG, DMSG or EMSG for stroke signals - and the air port is 1/8".
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 MARU25X160S 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 50.0 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) of 40 um filtered air at 30-800 mm/s.
Needle screws at each end meter the exhaust, so the last part of the 160 mm travel decelerates gently. Turn them in for heavier loads, out for faster cycling. Without cushioning a fast stroke can hammer the aluminium covers; the riveted stainless barrel stays sealed either way.
