Airtac MARF Stainless Steel Mini Air Cylinder MARF20X10S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF20X10S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MARF20X10S
Ten millimetres of travel, none of the compromises: the MARF20X10S keeps double-acting drive, two-way adjustable cushioning and an integrated front flange in a 20 mm bore that generates 157 N of push and 131.9 N of pull at 0.5 MPa, or 219.8 N at 0.7 MPa, topping out at 32 kgf theoretical. Its stainless barrel and hard-chrome 8 mm rod handle humid or lightly washed corners that dull painted mini cylinders.
Because the stroke is so short, work it with honesty: plan on about 94 N of real force at 0.5 MPa rather than the 157 N rating, enough to seat, detect or clamp a small part in one crisp hit. Operating range is 0.15-1.0 MPa (22-145 psi) with 30-800 mm/s speed, and the standard-fit magnet lets CMSG, DMSG or EMSG switches report the tiny stroke without special ordering.

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 MARF20X10S Is Used
PCB test-nest presser
Presses a board onto pogo pins in a test fixture, the 10 mm stroke limiting travel so the pins are never overstroked.
Bowl-feeder gate latch
Traps parts at a vibratory feeder outlet; the cushion stops the gate slamming home in its 10 mm of travel.
Presence check on an assembly line
Confirms a small cover is seated before a screwdriving cycle starts, signalled through a DMSG switch on the standard magnet.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X10S the Right Cylinder?
At 20 mm the bore is the smallest MAR offers; if a clamp needs more muscle, the MARF25X10S reaches 245.3 N at the same 0.5 MPa. The 10 mm stroke is a standard catalogue item, nowhere near the 500 mm ceiling, so delivery is off the shelf. Do not use the bare cylinder as a position lock - on air loss it simply drifts back or forward; the cushions merely soften the two ends. Mounting comes from the flange rolled into the front cover, with no separate foot to buy.
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 MARF20X10S FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa push reaches 219.8 N. The 20 mm bore tops out at 32 kgf theoretical. Air connection is a 1/8 port (PT, G or NPT) and the rod thread is M8x1.25.
Even a short stroke can hammer its covers at 800 mm/s. The variable air cushion at each end is trimmed with needle screws on commissioning, so the MARF20X10S lands quietly whether it is clamping, checking or gating.
