Airtac MARU Stainless Steel Mini Cylinder MARU32X160S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X160S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 160mm 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 MARU32X160S
For gates, pushers and lifters needing a longer reach, the MARU32X160S extends a 402 N-class 32 mm bore over 160 mm of travel. The double-acting piston carries a magnet as standard and runs on a variable cushion at both ends, while the up-facing bracket riveted to the front cover bolts the cylinder to the machine without extra hardware.
Working figures matter more than brochure ratings: at 0.5 MPa count on about 241 N of real push force, and halving the 41 kgf vertical rating leaves roughly 20 kg of lift capability. The stainless barrel and 20 um hard-chrome rod stand up to washdown better than painted minis. Supply air at 0.15-1.0 MPa (22-145 psi) and cycle anywhere from 30 to 800 mm/s.

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 MARU32X160S Is Used
Pallet-stacker fork guide
160 mm of travel positions the guide roller while 402 N at 0.5 MPa resists dock impacts.
Tote pusher on roller conveyor
The stainless body shrugs off warehouse dust, and the both-end cushion stops totes gently at the lane end.
Machine guard interlock actuator
A retract pull of 346 N draws the interlock pin home, and the up mount fixes under the guard frame.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X160S the Right Cylinder?
Next sizes either side: 25 mm bore for 245 N push or 40 mm for 628 N, both at 0.5 MPa; choose 32 mm when 402 N fits the job. Over 160 mm of travel keep side load low so the 12 mm rod does not bend, and remember air loss frees the piston - add a rod lock where the load must stay put. Magnet feedback via CMSG, DMSG or EMSG switches needs no special piston. The MARF32X160S front-flange variant suits face mounting instead.
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 MARU32X160S FAQ
At 0.5 MPa: 402 N push, 346 N pull. At 0.7 MPa: 563 N push, 484 N pull. Theoretical peak is 82 kgf at 1.0 MPa. Ports are 1/8 inch, the rod thread is M10x1.25, and cycling runs 30-800 mm/s.
No. Like any plain double-acting cylinder it drifts when air is lost; the variable cushion only softens the stroke ends. Specify a rod lock for held loads. Meanwhile the standard magnet with CMSG, DMSG or EMSG switches gives position signals along the stainless barrel.
