Airtac MARF Stainless Steel Mini Air Cylinder MARF20X60S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF20X60S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MARF20X60S
Short, stiff and flange-ready, the MARF20X60S gives a 20 mm bore just 60 mm of travel in a body whose front bracket is rolled in, not bolted on. Double acting on both faces, it pushes 157 N and retracts with 132 N at 0.5 MPa (73 psi), while the variable cushion at each end trims stop shock so faster cycles stay quiet.
Grease-retaining two-way piston seals and a hard-chrome rod keep friction low cycle after cycle, and the stainless barrel stands up to washdown that dulls painted mini bodies. Position sensing is built in: the standard piston magnet accepts CMSG, DMSG or EMSG switches directly. In practical terms the 157 N push equals 16 kgf theoretical, so size vertical work to roughly 8 kg to keep a 2:1 margin.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MARF20X60S Is Used
PCB stand-off staking press
Presses nylon stand-offs into router boards with a working force near 94 N at 0.5 MPa - firm on plastics yet gentle enough for electronics.
Cosmetic carton flap tucker
Folds the final side flap on small cartons every cycle, with the cushion needles damping the 60 mm end stops.
Pharma vial lane diverter
Swings a vial lane between fill and reject chutes through a Y-knuckle screwed onto the M8x1.25 rod thread.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X60S the Right Cylinder?
If 157 N at 0.5 MPa feels tight for the load, the next bore up, 25 mm, reaches 245 N push; there is no MAR bore below 20 mm. Like every double-acting MA cylinder this one holds no position when air pressure drops - fit a rod lock where the tool must stay put. The integrated front flange bolts the 60 mm body straight to a machine plate, so no separate FA or LB foot hardware is needed. Air ports on this bore are 1/8".
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 MARF20X60S FAQ
Push 157 N and pull 132 N at 0.5 MPa (73 psi); push 220 N and pull 185 N at 0.7 MPa (102 psi); 32 kgf theoretical peak at 1.0 MPa. The air supply window is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-800 mm/s.
Adjust the needle screws at both heads on first commissioning until the 60 mm end stops land softly; the variable cushion then adapts to your load and speed. Sensing needs no option code - the magnet ships inside the piston, so CMSG, DMSG or EMSG switches mount straight onto the barrel.
