Airtac MARU Stainless Steel Mini Cylinder MARU32X100S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X100S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MARU32X100S
With 402 N of push and 345.6 N of pull at 0.5 MPa, the MARU32X100S covers mid-range clamping and pushing jobs in a compact round body. AirTAC rivets a stainless-steel barrel to aluminium-alloy covers over a hard-chrome plated rod (20 um), so it shrugs off mild corrosion and washdown far better than painted-steel minis in damp or food-line spots.
Motion is double acting with a variable air cushion at both ends, so faster strokes stop without pounding the covers, and it bolts down through its own integrated top (U) bracket - no separate flange or foot to buy. At 0.5 MPa, plan for about 241 N of real work rather than the full 402 N rating, and the bore 32 package lifts about 20 kg vertically once you keep a 2:1 margin. The piston magnet ships standard, ready for CMSG, DMSG or 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 MARU32X100S Is Used
Carton diverter gate
Drives the pusher finger that sweeps snack cartons off a takeaway belt into a reject lane; 100 mm of travel clears the lane width and 402 N push at 0.5 MPa moves the stream without stalling.
Bench crimp fixture
Crimps spade terminals onto wire harnesses in a small workholding; 402 N at 0.5 MPa (563 N at 0.7 MPa) suits light-gauge terminals, and the variable cushion stops the die without bounce.
Flap tuck station
Folds and tucks the end flaps on e-commerce mailer boxes ahead of the taping head; the 345.6 N pull at 0.5 MPa retracts the tuck horn clear before the next carton indexes.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X100S the Right Cylinder?
Compare bores by real force: the bore 25 MAR manages 245.3 N push at 0.5 MPa, this bore 32 gives 402.2 N, and stepping up to bore 40 buys 628.3 N. Keep about 241 N as the practical working push at 0.5 MPa, and note the MAR will not hold position if air is lost - the rod drifts, so a rod lock is needed for parked loads. The integral top bracket removes the need for an add-on flange, and the standard magnet accepts CMSG, DMSG or 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 MARU32X100S FAQ
At 0.5 MPa the bore 32 piston pushes 402.2 N and pulls 345.6 N; raise supply to 0.7 MPa and those become 563.0 N push and 483.8 N pull; the theoretical maximum force is 82 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The barrel is stainless steel with aluminium-alloy covers rolled on, and the carbon-steel rod is hard-chrome plated to 20 um - a combination that resists mild corrosion and routine washdown far better than painted or bare-aluminium mini cylinders. It is a round-body riveted design, not a tie-rod unit.
