Airtac MARU Stainless Steel Mini Cylinder MARU32X170S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X170S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 170mm 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 MARU32X170S
The 170 mm-stroke member of AirTAC's MA round-body family, MARU32X170S is double acting with a variable air cushion at both ends and an up-mount bracket rolled into the front cover, so it bolts straight onto the machine frame. At 0.5 MPa it pushes 402 N and pulls 346 N, rising to 563 N at 0.7 MPa - a 32 mm bore class that suits clamps and ejectors on medium presses and packaging heads.
The stainless barrel with its hard-chrome plated 12 mm rod shrugs off coolant mist and washdown that pit painted-steel minis, while the grease-storing two-way piston seal keeps lubrication inside the tube. Plan tooling against about 241 N of real working force at 0.5 MPa - roughly 60 percent of the 402 N rating - and note the piston magnet is already fitted, so CMSG, DMSG or EMSG switches drop on with no special order.

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 MARU32X170S Is Used
Clamshell heat sealer press
402 N at 0.5 MPa closes a 32 mm class sealer arm through 170 mm of travel, with the dual cushions absorbing the clamp bottom-out.
Carton flap tucker
A top-mounted MAR drives the flap plough on a case packer; the integrated bracket skips a separate flange plate and the magnet flags each stroke for the PLC.
Bottle-rinse tunnel gate
Stainless barrel and chrome rod hold up in the wet zone of a rinse tunnel, where painted mini bodies would bloom with rust.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X170S the Right Cylinder?
Step down to the 25 mm bore (245 N push at 0.5 MPa) for lighter gates, or up to 40 mm (628 N) when the load climbs. Keep in mind the MAR will not hold position on air loss - pressure off means the rod drifts, so a rod lock is the fix if the stroke must stay put. The 170 mm span puts real leverage on the 12 mm rod, so couple the load with a flex joint or guide it in linear bearings rather than letting it side-load the rod. I and Y knuckles thread onto the M10x1.25 nose; the 1/8" port keeps plumbing simple and the built-in magnet pairs with CMSG / DMSG / EMSG switches.
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 MARU32X170S FAQ
At 0.5 MPa: 402 N push and 346 N pull. At 0.7 MPa: 563 N push and 484 N pull. The theoretical maximum for the 32 mm bore is 82 kgf at the 1.0 MPa (145 psi) ceiling. Working pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and rod speed runs 30-800 mm/s.
No. Every MA-series piston carries a magnet as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel anywhere along the 170 mm stroke. The up-mount bracket is part of the front cover too - no flange or foot accessory to order.
