Airtac MARF Stainless Steel Mini Air Cylinder MARF32X75S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X75S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MARF Stainless Steel Mini Air Cylinder MARF32X75S
A 32 mm bore MAR with an integrated front flange, this cylinder is double acting with a variable air cushion at both ends. At 0.5 MPa it pushes 402 N and pulls 346 N, stepping up to 563 N at 0.7 MPa - force enough for fixture clamping and light pressing on a 75 mm stroke. For a durable margin, plan the mechanism around roughly 241 N of working thrust rather than the full rating.
Construction follows the round MA pattern: a stainless-steel barrel rolled tight against aluminium-alloy covers and a stainless block, with a hard-chrome plated 12 mm rod sliding through. That riveted body shrugs off the washdown splash and humid air that eat painted-steel minis. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the tube, and both cushion needles are trimmed on first run.

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 MARF Stainless Steel Mini Air Cylinder MARF32X75S Is Used
Drill-jig clamping
Swings a clamp arm onto aluminium brackets before a drilling cycle, with 402 N at 0.5 MPa ample for fixture-grade holding.
Carton stopper gate
Raises and lowers a stopper blade that diverts 5 kg cartons at a sorter merge point, cushioned so the gate never slams.
Small press-fit station
Seats nylon bushings into pump housings where roughly 241 N of working force suffices and the stainless barrel resists cutting-fluid splash.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X75S the Right Cylinder?
For 75 mm of travel the 32 mm bore sits mid-range: drop to the 25 mm MAR (245 N push at 0.5 MPa) for lighter gates, or step to 40 mm (628 N) when the load climbs. Like any double-acting cylinder it will not hold position if air is lost - the piston drifts - so add a rod lock where the load must stay put. Front-flange mounting is already on the body and the built-in magnet needs no special-order piston; if the tooling swivels, I and Y rod knuckles thread onto the M10x1.25 rod. Strokes beyond the 500 mm standard ceiling for this bore are made to order.
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 MARF Stainless Steel Mini Air Cylinder MARF32X75S FAQ
At 0.5 MPa the MARF32X75S pushes 402 N and pulls 346 N; at 0.7 MPa the figures rise to 563 N and 484 N, with a theoretical ceiling of 82 kgf at 1.0 MPa. Sizing around about 241 N of continuous thrust leaves a solid safety margin.
No. Every MA-series cylinder ships with the piston magnet fitted as standard, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel for stroke-end signalling without a special-order piston.
