Airtac MARU Stainless Steel Mini Cylinder MARU32X175S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X175S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 175mm 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 MARU32X175S
Built around a rolled stainless tube and a 12 mm hard-chrome rod, the MARU32X175S is AirTAC's 175 mm-stroke mini cylinder with double-acting power, needle-adjustable cushioning at each end, and a top-mount bracket already on the front cover. Its 32 mm bore produces 402 N of push and 346 N of pull at 0.5 MPa, or 563 N if you feed it 0.7 MPa.
The riveted round body has no external fasteners and no painted surfaces to chip, which is why these minis survive humid food lines and outdoor gantries where plain aluminium shells corrode. In vertical work the 402 N rating equals about 41 kgf, so halve it and you can lift a 20 kg part with a 2:1 margin; horizontally, count on close to 241 N of usable force at 0.5 MPa. The standard piston magnet accepts CMSG / DMSG / EMSG switches straight away.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MARU32X175S Is Used
Aluminum housing ejector
On a CNC cell out-feed, the 402 N push at 0.5 MPa pops finished housings off the fixture across 175 mm, cushioned at both ends.
Autoclave tray pusher
The stainless round body laughs at the steam-adjacent humidity of a lab sterilizer line, keeping travel smooth over the full 175 mm.
Bakery tray divider
The top bracket rows divider blades down between trays, while the standard piston magnet feeds position signals to the oven PLC through a DMSG switch.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X175S the Right Cylinder?
For lighter work the 25 mm bore gives 245 N at 0.5 MPa; step to 40 mm (628 N) when you need real punch. Note that this cylinder slides wherever the load takes it once air is removed - fit a rod lock if the position has to survive a supply drop. The integrated top bracket saves you a flange plate, and I or Y knuckles fit the M10x1.25 rod thread. With 175 mm of unsupported travel, guide the load or use a coupling that absorbs misalignment so the 12 mm rod never sees side thrust.
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 MARU32X175S FAQ
Push at 0.5 MPa is 402 N, pull at 0.5 MPa is 346 N, push rises to 563 N at 0.7 MPa, and the 32 mm bore tops out at a theoretical 82 kgf at 1.0 MPa (145 psi). Run it anywhere from 0.15-1.0 MPa (22-145 psi); proof pressure is 1.5 MPa (215 psi); rod speed 30-800 mm/s.
Both stroke ends carry a variable cushion: on first run-up, open the needle screws fully, then turn them in until end-of-stroke thump disappears. That lets you run up to 800 mm/s or move heavier loads without hammering the covers. The cushion softens the stop - it never locks the piston.
