Airtac MARU Stainless Steel Mini Cylinder MARU25X450S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X450S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 450mm 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 MARU25X450S
A 450 mm reach from a 25 mm bore makes the MARU25X450S the long-arm choice of the MA mini family, wrapped in a rolled stainless round barrel rather than a painted tube that chips and rusts. The double-acting piston moves on air in both directions, and needle-adjustable cushions at each end tame the stop.
Rated output is 245 N of push and 206 N of pull at 0.5 MPa, with 343 N of push available at 0.7 MPa and 50 kgf theoretical at 1.0 MPa. Sizing rule of thumb: expect around 147 N of dependable work force, or about 12 kg of vertical lift at a 2:1 margin. The up-mount bracket is part of the front cover itself, so the long body anchors to the frame without a bolt-on foot.

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 MARU25X450S Is Used
Tote lift between two levels of a pick module
About 12 kg of vertical lift at a 2:1 margin raises plastic totes from a conveyor up to an upper pick shelf across 450 mm.
Pusher blade on an AGV transfer deck
The 450 mm stroke slides palletized loads off the AGV deck while both-end cushioning protects the deck during fast cycles.
Lid raise on a large mixing vessel clamp ring
Cushioned 450 mm travel lifts the clamp ring clear for cleaning, with the standard magnet confirming open and closed positions to the controller.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X450S the Right Cylinder?
Long strokes demand clean alignment: keep side loads off the 10 mm rod with external guides, especially over 450 mm of travel where a small misalignment multiplies. If 245 N of push at 0.5 MPa overshoots the job, the 20 mm bore at 157 N saves air and money; if it undershoots, step to the 32 mm bore and its 402 N. Do not rely on the cylinder to hold a mid-stroke load without air - the piston floats when pressure drops, so specify a rod lock for secure stops. The magnet is included as standard for CMSG, DMSG or EMSG position 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 MARU25X450S FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa the figures become 343.4 N push and 288.5 N pull. Theoretical maximum is 50.0 kgf at 1.0 MPa. The bore uses 1/8 inch ports and an M10x1.25 male rod thread.
Nothing separate to buy: the U in the model code means the front cover itself carries a top-mount bracket, rolled into the stainless body. The 10 mm rod accepts I or Y knuckle accessories on its M10x1.25 thread, and operating pressure runs 0.15-1.0 MPa (22-145 psi).
