Airtac MARU Stainless Steel Mini Cylinder MARU32X220S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X220S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 220mm 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 MARU32X220S
Where a 220 mm reach is needed without stepping up in bore size, the MARU32X220S fills the gap: 32 mm of bore in a rolled stainless round barrel, double acting and cushioned at both ends, with the top-facing bracket already part of the body. Riveted covers keep the slim profile sealed against splash and dust.
At 0.5 MPa the rod delivers 402 N out and 346 N back, and 563 N at 0.7 MPa. Working off about 241 N leaves ample reserve, and the vertical-lift equivalent is roughly 20 kg with a 2:1 safety margin - handy when sizing a lifting arm. Cushion needles trim the stop, speed spans 30-800 mm/s, and the standard magnet accepts CMSG / DMSG / EMSG switches.

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 MARU32X220S Is Used
Mast-shift assist on an order picker
Slides the pick tray across a 220 mm rack pitch; 402 N at 0.5 MPa moves a 30 kg tray with margin to spare.
Roller-gap setting on a slitter
Adjusts blade gap by pushing the upper roller block; the twin cushions settle each setting without shock to the gearbox.
Tote pusher at a palletiser infeed
Pushes a filled tote onto the drag chain; an EMSG switch on the barrel flags full retraction so the next tote is released.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X220S the Right Cylinder?
Bore neighbours bracket this size well: 25 mm MAR cylinders manage 245 N at 0.5 MPa while 40 mm units reach 628 N, leaving the 32 mm barrel as the balanced middle choice. The 220 mm stroke is standard, but keep the rod in pure thrust - side loads at this length bend rods and wear seals, so guide sliding loads on their own rails. Position is not held on air loss; a rod lock cylinder covers that job. Magnet and top bracket ship fitted from the factory.
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 MARU32X220S FAQ
At a glance: 402 N push and 346 N pull at 0.5 MPa, 563 N push and 484 N pull at 0.7 MPa, 82 kgf theoretical maximum at 1.0 MPa, 1/8 inch ports, a 12 mm rod with M10x1.25 thread, and a 220 mm stroke well inside the 500 mm standard limit for this bore.
The stainless barrel, hard-chrome plated 12 mm rod and riveted aluminium covers tolerate splash and humidity far better than painted minis. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) between -20 and +70 C and it will hold up in most shop-floor environments.
