Airtac MARU Stainless Steel Mini Cylinder MARU32X65S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X65S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 65mm 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 MARU32X65S
Short-travel stations are where the MARU32X65S fits best: a 65 mm stroke on a 32 mm bore, double acting, with variable cushions you can needle in during first commissioning. The U bracket is machined into the front cover itself, so the cylinder bolts directly onto the machine face. Push force is 402 N at 0.5 MPa, with 346 N on the return stroke.
Washdown lines favor the riveted stainless barrel over painted minis, and the chrome-plated 12 mm rod resists scoring from abrasive dust. Plan real workloads at about 241 N of push, or trust it to lift roughly 20 kg vertically once a 2:1 margin is applied to its raw 41 kg lift rating.

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 MARU32X65S Is Used
Carton coder label head
Lifts the print head onto passing cartons for a 65 mm print band, then clears for the next box at up to 800 mm/s.
Small-part gripper jaw
Closes a two-finger gripper on machined bushings, where 346 N of pull retracts the jaw cleanly between picks.
CNC guard door latch
Actuates the interlock pin on a machine guard, with magnet-driven CMSG switches confirming lock and release to the PLC.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X65S the Right Cylinder?
If your load is lighter, a bore-25 MAR still gives 245 N of push at 0.5 MPa; when the cycle needs more muscle, bore 40 reaches 628 N. The magnet is a standard fitting, so CMSG, DMSG or EMSG switches drop onto the barrel without a special piston order. Remember that a plain MAR has no holding function - if air is lost the rod will creep, so add a rod lock wherever position must persist.
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 MARU32X65S FAQ
Bore 32 gives 402 N push and 346 N pull at 0.5 MPa, 563 N push and 484 N pull at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
Back the needle screws out before the first stroke, then turn them in gradually until end-of-stroke knock disappears. The variable air cushion works at both ends across the 30-800 mm/s speed range, so you can run faster cycles without hammering the aluminium covers.
