Airtac MARF Stainless Steel Mini Air Cylinder MARF32X65S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X65S is a genuine double acting + cushion (front 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 MARF Stainless Steel Mini Air Cylinder MARF32X65S
A 65 mm throw on a Dia 32 bore covers most clamp-and-eject jobs with room to spare, and the MARF32X65S brings 402 N of push plus 346 N of pull at 0.5 MPa to that work. Its front flange is rolled into the front cover itself, so there is no loose bracket to align - the cylinder seats straight onto the mounting face.
The two-way seal in the piston doubles as a grease store, keeping the stainless barrel running smoothly between services, and the cushion screw at each end is set with a screwdriver in minutes. On real-world numbers, expect about 241 N of usable push at 0.5 MPa - call it 20.5 kg lifted vertically with a 2:1 margin - and a CMSG, DMSG or EMSG switch can sit anywhere on the tube, since the magnet is standard equipment.

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 MARF32X65S Is Used
CNC fixture clamp
65 mm of stroke clears a chip-guard swing before clamping; 402 N at 0.5 MPa keeps aluminium blanks seated against the stop.
Bench press-fit arbor
Presses bushings into small housings on a fixture; the cushioned stop avoids bounce at the bottom of the press stroke.
Bottle line reject kicker
Knocks out-of-spec bottles off a filler conveyor; the standard magnet feeds a CMSG switch so the reject counter logs every kick.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X65S the Right Cylinder?
If 65 mm is more travel than the task needs, a shorter-stroke Dia 32 MAR carries the same 402 N; if the job needs more muscle, the Dia 40 bore steps up to 628 N at 0.5 MPa. Do not rely on this cylinder to park a load: when supply air drops, the piston drifts rather than holds, so spec a rod lock for held positions. The 1/8" air port and M10x1.25 rod thread match common fittings and I or Y knuckles.
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 MARF32X65S FAQ
Extension force is 402 N and retraction 346 N at 0.5 MPa; at 0.7 MPa those become 563 N and 484 N; the theoretical top figure is 82 kgf at 1.0 MPa. Operating band is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), rod speed 30-800 mm/s.
Open both cushion needle screws fully, run the piston through a few slow cycles, then close each screw until end-of-stroke bounce disappears. The cushion is variable at both ends, so even a fast 800 mm/s approach can land softly on the covers.
