Airtac MARU Stainless Steel Mini Cylinder MARU32X350S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X350S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MARU32X350S
In the 32 mm force class the MARU32X350S pushes 402 N and pulls 346 N at 0.5 MPa (563 N push at 0.7 MPa), delivered by a double-acting round-body cylinder that carries its own top (U) mounting bracket, so no separate flange or foot bracket is bought alongside it. The 350 mm stroke suits long-throw work, and a variable air cushion at both ends trims end-of-stroke shock while speed runs 30-800 mm/s.
A riveted stainless-steel barrel with a 20 um hard-chrome plated rod shrugs off washdown and damp shop air far better than painted minis, and the built-in magnet (standard, shown as S in the code) accepts CMSG, DMSG or EMSG switches without special ordering. On vertical duty the theoretical lift is about 41 kg at 0.5 MPa; halve that for a 2:1 margin and plan parts around 20 kg.

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 MARU32X350S Is Used
Tote elevator on an assembly line
Lifts totes of electronics housings between conveyor levels with 402 N of push; the 350 mm stroke covers a two-tier lift and the cushion stops the basket slamming at the top.
Long-throw carton pusher
Ejects shipping cartons off a cross-belt sorter, with 346 N of pull on the return stroke and CMSG switches confirming extend and retract each cycle.
Oven door actuator
Slides a paint-cure oven door open over 350 mm; the stainless barrel and chrome rod cope with warm, damp air near the oven where painted minis would pit.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X350S the Right Cylinder?
If 402 N at 0.5 MPa is more than the job needs, a 25 mm bore MAR gives 245 N; if the load stalls, move up to a 40 mm bore at 628 N. Over 350 mm of travel, guide the load externally or pick up an I or Y knuckle for the M10x1.25 rod thread to keep side load off the 12 mm rod. Remember the rod drifts when air pressure is gone - the cushion only softens the stroke end - so a rod lock is the answer where parking matters. Standard PT ports here; G and NPT can be ordered.
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 MARU32X350S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa push rises to 563.0 N (pull 483.8 N). Theoretical maximum output at 1.0 MPa is 82.0 kgf for the 32 mm bore. Running pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and speed can be set anywhere from 30 to 800 mm/s.
The up (U) bracket is rolled into the front cover assembly, so the cylinder bolts straight to the machine face - no separate flange or foot is needed, and I or Y rod knuckles still thread onto the M10x1.25 rod. The magnet is built in as standard, so CMSG, DMSG or EMSG switches slide onto the barrel without special-order pistons.
