Airtac MARU Stainless Steel Mini Cylinder MARU32X300S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X300S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MARU32X300S
Three hundred millimetres of travel from a 32 mm bore makes the MARU32X300S a long-reach mini: a riveted stainless round barrel, a 12 mm hard-chrome plated rod, and a top bracket integrated into the front cover so no separate foot or flange is needed. It is double acting with a variable cushion at each end, adjustable on commissioning via the needle screws.
The bore pushes 402.2 N and pulls 345.6 N at 0.5 MPa (about 72 psi), rising to 563.0 N and 483.8 N at 0.7 MPa (about 102 psi), against a theoretical 82 kgf peak at 1.0 MPa. Size real work at about 241 N - still roughly 20 kg of vertical lift after halving for a 2:1 margin. The piston magnet is standard, letting CMSG, DMSG or EMSG switches bolt to the tube without special ordering. It runs on air filtered to 40 um, 0.15-1.0 MPa (22-145 psi), from -20 to +70 C.

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 MARU32X300S Is Used
Sluice gate on a water-treatment flume
Pulls a small sluice plate across a 300 mm channel; the stainless barrel handles constant outdoor humidity.
Tray elevator on a snack-food line
Hoists trays of roughly 15 kg about 300 mm between conveyor levels, cushions absorbing each landing.
Station-lock plunger on a rotary dial table
Acts as a 300 mm lock-and-advance plunger for a 12-station rotary indexer needing 402 N of push.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X300S the Right Cylinder?
Run the numbers against neighbours: at 0.5 MPa a 25 mm bore manages 245.3 N push while a 40 mm bore reaches 628.3 N, so this 32 mm at 402.2 N sits in the middle. If the payload needs more than the 241 N working figure, upsize. A 300 mm stroke amplifies side-load problems on the 12 mm rod - guide the carriage externally and check rod alignment at both stroke ends. For holding a part against gravity during an air loss, the MAR alone is not the answer; pair it with a rod lock. The built-in top bracket mounts directly, and the standard magnet accepts CMSG or DMSG sensing anywhere along the barrel.
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 MARU32X300S FAQ
At 0.5 MPa (about 72 psi): 402.2 N push, 345.6 N pull. At 0.7 MPa (about 102 psi): 563.0 N push, 483.8 N pull. Theoretical maximum 82 kgf at 1.0 MPa. Rated for 0.15-1.0 MPa (22-145 psi) supply and 30-800 mm/s piston speed.
The rolled stainless tube and hard-chrome plated rod resist mild corrosion and washdown better than painted-steel minis, useful in damp food, outdoor or wash-line environments - and the riveted MA construction keeps the 300 mm body rigid and sealed.
