Airtac MARU Stainless Steel Mini Cylinder MARU25X75SY
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X75SY is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MARU25X75SY
Under the 75 mm stroke sits a 25 mm stainless round barrel with rolled-in aluminium covers and a hard-chrome plated 10 mm rod doing the work. Double acting and cushioned at both ends, this up-mount MAR delivers 245 N pushing and 206 N pulling at 0.5 MPa.
In day-to-day terms the same cylinder lifts about 12 kg vertically once the usual 2:1 margin is kept, or roughly 147 N of steady work. The riveted stainless tube shrugs off washdown mist that swells painted minis, and the built-in magnet - standard, not an option - lets a CMSG or DMSG switch clip straight on.

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 MARU25X75SY Is Used
Diverter gate push
Swinging a pusher gate across a packaging conveyor: 245 N at 0.5 MPa clears a carton lane quickly at a mid-band speed.
Connector staking
A benchtop staking head pressing crimp terminals, with the variable cushion so the dies seat gently at end of stroke.
Indexed fixture check
Clamping an indexed drilling fixture and confirming closure through a DMSG switch riding on the standard magnet.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X75SY the Right Cylinder?
Sizing around this bore: a 20 mm MAR manages only 157 N at 0.5 MPa, while the next step up, 32 mm, delivers 402 N - pick 25 mm when the load sits between roughly 150 and 240 N. Supply spans 0.15-1.0 MPa (22-145 psi). Note the cylinder will not hold a position if air is lost - the piston drifts - so add a rod lock where holding matters. The standard magnet pairs with CMSG / DMSG / EMSG switches, and I or Y rod knuckles still thread onto the M10x1.25 male rod.
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 MARU25X75SY FAQ
At 0.5 MPa it pushes 245 N and pulls 206 N; at 0.7 MPa push rises to 343 N and pull to 288 N. The theoretical maximum at 1.0 MPa is 50 kgf. The 10 mm hard-chrome rod runs on a 1/8" port with an M10x1.25 male thread, speed 30-800 mm/s.
The up-facing front bracket is part of the riveted body, so no separate flange or foot is used on MAR - I or Y knuckles still fit the rod. A magnet comes built in, letting CMSG, DMSG or EMSG switches clip over the stainless barrel to signal stroke ends.
