Airtac MARF Stainless Steel Mini Air Cylinder MARF20X260S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF20X260S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø20mm bore and 260mm 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 MARF20X260S
Need just over a quarter metre of travel from a mini cylinder? The MARF20X260S gives 260 mm of double-acting stroke on a 20 mm bore, front-flange mount included in the head, and a variable cushion at each end to tame the arrival. At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N. The hard-chrome 8 mm rod is threaded M8x1.25 and air enters through a 1/8 in port.
The riveted stainless-and-aluminium body suits damp packaging lines and outdoor panels where painted round cylinders corrode fast. Because the magnet is fitted as standard, CMSG, DMSG or EMSG switches bolt on for end-of-stroke confirmation with zero special ordering. Size the load around 94 N of working push (60 percent of rating) or lift about 8 kg vertical with a 2:1 margin. Supply 0.15-1.0 MPa (22-145 psi); speed range 30-800 mm/s.

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 MARF20X260S Is Used
Case push-off
Pushes filled 200 g pill cases from an infeed lane onto a shrink-wrap conveyor, one case per stroke.
Dosing gate
Opens and closes a sliding powder gate on a small dosing line, with the magnet flagging open and shut positions.
Drawer index
Advances a light drawer of SMT feeders one pitch per cycle inside a component kitting station.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF20X260S the Right Cylinder?
Where force is marginal, jump one bore: 245 N at 0.5 MPa from bore 25 or 402 N from bore 32, both in the same round body style. Bore 20's 157 N push at 0.5 MPa suits light index and eject work over this 260 mm travel. Do not expect the cylinder to park the load if air pressure drops; the variable cushion eases the stroke ends but holds nothing - specify a rod lock for that. Sensing comes free of charge since the magnet ships as standard and accepts CMSG, DMSG and EMSG switches. On a long 8 mm rod, keep the payload guided so side loads stay off the rod and seals.
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 MARF20X260S FAQ
Expect 157 N push and 131.9 N pull at 0.5 MPa. Raise the supply to 0.7 MPa for 219.8 N push and 184.7 N pull, and the theoretical maximum force is 32.0 kgf at 1.0 MPa. It runs on filtered air at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), 30-800 mm/s.
The front-flange bracket is built into the head and rolled up with the body, so the MARF20X260S bolts flush to a machine wall with no separate flange or foot to buy. I and Y rod knuckles still fit the M8x1.25 rod thread if the linkage needs them.
