Airtac MARU Stainless Steel Mini Cylinder MARU25X150S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X150S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MARU25X150S
A 150 mm stroke on a 25 mm bore gives the MARU25X150S long reach in a slim round package: double acting, variable air cushion at both ends, and the up/top front bracket moulded into the MA body so no separate flange or foot bracket is ever ordered. Air at 0.15-1.0 MPa (22-145 psi) drives the rod both ways at 30-800 mm/s.
The 245.3 N push at 0.5 MPa corresponds to about 25 kgf of thrust, which halves to roughly 12 kg for vertical lifting with a 2:1 safety margin - enough for small chutes, gates and light press heads. The integrated magnet is standard, dropping CMSG or DMSG switches on for cycle counting, and the aluminium covers riveted to the stainless barrel keep the whole unit light over the long travel.

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 MARU25X150S Is Used
Pallet strapper tensioner assist
Positions the strap guide head on a semi-automatic strapper; the long 150 mm reach clears the pallet edge while the cushion settles the return.
Machine guard slide
Opens and closes an interlocked sliding guard door on a small press, with a CMSG switch on the standard magnet proving the closed position to the safety relay.
Tote push-off arm
Ejects filled plastic totes from a picking shelf in a warehouse buffer; 245 N at 0.5 MPa slides a 8 kg tote on roller track without effort.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X150S the Right Cylinder?
Force ladder for reference: 20 mm bore delivers 157.0 N at 0.5 MPa and 32 mm bore delivers 402.2 N, so pick this 25 mm model when the task needs between about 100 and 200 N of working push. With 150 mm of exposed rod, external guidance is strongly advised - side loads that a short stroke shrugs off will wear the bushing and bend a 10 mm rod here.
Air loss means drift, not hold; specify a rod lock alongside this cylinder whenever a raised load must stay put. The body's own top mount fixes to the machine plate directly, the rod thread is M10x1.25 for I or Y knuckles, and 1/8" ports keep plumbing simple.
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 MARU25X150S FAQ
No - like any plain double acting cylinder it drifts with the load once pressure is lost; the variable cushion only softens the last millimetres of travel, it is not a brake. If your 150 mm stroke carries a raised part, add an AirTAC rod lock. For force planning: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N and 288.5 N at 0.7 MPa, 50 kgf theoretical maximum.
Three things buyers usually order separately: the top/up mounting bracket (integrated into the body), the position-sensing magnet (standard, accepts CMSG, DMSG and EMSG switches), and the variable air cushion at both ends. The stainless barrel and hard-chrome plated rod then handle humid or washdown-prone sites without extra protection.
