Airtac MARU Stainless Steel Mini Cylinder MARU32X140S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X140S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 140mm 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 MARU32X140S
The MARU32X140S pairs a 32 mm stainless round barrel with a 140 mm stroke and an up-facing mounting boss rolled into the front cover, so the cylinder bolts straight to the machine top plate without a separate bracket. Double acting with a variable cushion at each end, it pushes 402 N and pulls 346 N at 0.5 MPa, rising to 563 N push at 0.7 MPa, across a 0.15-1.0 MPa (22-145 psi) supply and speeds of 30-800 mm/s.
The riveted round body and hard-chrome plated 12 mm rod shrug off washdown and damp plant air far better than painted-steel minis. Because this is a 402 N-class pusher, plan on roughly 241 N of real working force at 0.5 MPa, or about 20 kg of vertical lift once you halve the rating for a 2:1 margin. A magnet ships inside the piston as standard, so CMSG, DMSG and EMSG switches snap straight onto the barrel for end-of-stroke signals.

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 MARU32X140S Is Used
PCB test fixture press
The 402 N push at 0.5 MPa gives enough seating force for connector press-fit and go/no-go test rigs on electronics lines.
Bottling line gate actuator
The stainless barrel and chrome rod handle washdown near filler gates, while the 140 mm stroke clears the full lane width.
Packaging tray lid lift
Variable cushion at both ends stops the lid arm slamming at 140 mm of travel, and the up mount bolts under the frame.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X140S the Right Cylinder?
At 402 N push per 0.5 MPa, this 32 mm bore covers clamping and pressing jobs that a 25 mm MAR (245 N) cannot; if you need more than about 628 N, step up to the 40 mm bore. Note that with air lost the piston drifts freely - for holding a load at 140 mm of travel, add a rod lock cylinder instead. The built-in top bracket mounts directly on the machine, and I or Y rod knuckles still thread onto the M10x1.25 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 MARU32X140S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa the figures are 563 N push and 484 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Ports are 1/8 inch, the rod thread is M10x1.25, and the 12 mm rod cycles at 30-800 mm/s.
Yes - turn the cushion needle screws at both ends until the 140 mm stroke decelerates without knock. The variable air cushion softens each stop; the stainless barrel and hard-chrome rod then tolerate washdown and humidity, and the standard piston magnet works with CMSG, DMSG and EMSG switches.
