Airtac MARU Stainless Steel Mini Cylinder MARU32X210S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X210S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 210mm 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 MARU32X210S
Longer index moves are where this model earns its keep: the MARU32X210S puts 32 mm of bore inside AirTAC's riveted round-body format, giving a 210 mm stroke with the stainless barrel and hard-chrome 12 mm rod standing up to splash and humidity. The top-mount bracket is rolled into the body, so the cylinder lands on the machine frame without a separate flange or foot.
Push is 402 N and pull 346 N at 0.5 MPa, rising to 563 N at 0.7 MPa. Derate to about 241 N for long service life and the stroke still runs anywhere from 30 to 800 mm/s with the twin cushions soaking up end-of-travel shock. The magnet is factory-fitted, so CMSG / DMSG / EMSG switches mount straight onto the barrel.

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 MARU32X210S Is Used
Slide extension in a heat-exchanger assembly cell
Pushes a copper core 210 mm into its casing; 402 N at 0.5 MPa overcomes a light friction fit without marking the fins.
Depth stop drop on a tube-bending rig
Lowers a gauge block onto the bent tube; the twin cushions land the stop gently so the chrome surface is not marred.
Reject pusher at a checkweigher
Knocks underweight packs off the belt; a CMSG switch confirms retraction before the next pack enters, preventing double rejects.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X210S the Right Cylinder?
A 25 mm MAR bore tops out near 245 N at 0.5 MPa, so step up to this 32 mm barrel when loads creep past 240 N; a 40 mm bore at 628 N covers heavier presses. On a 210 mm rod, side load is the main enemy - guide the load externally or expect rod and seal wear. If the load must stay put through an air drop, the piston will drift; specify a rod lock instead. The integrated top bracket plus standard magnet mean there is no accessory hunting at order time.
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 MARU32X210S FAQ
It pushes 402 N and pulls 346 N at 0.5 MPa, 563 N and 484 N at 0.7 MPa, and theoretically 82 kgf at 1.0 MPa. Ports are 1/8 inch, the rod thread is M10x1.25 on a 12 mm rod, operating pressure spans 0.15-1.0 MPa (22-145 psi), and 210 mm sits inside the 500 mm standard stroke range.
Needle screws at both ends bleed air to soften the last millimetres of the 210 mm stroke - set them only after the cylinder is under real load. Mounting is by the factory-rolled top bracket alone; separate flanges and feet are not part of the MAR design. Sensor feedback comes from the standard magnet with CMSG, DMSG or EMSG switches.
