Airtac MARF Stainless Steel Mini Air Cylinder MARF63X350S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X350S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 350mm stroke, 1/4" 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 MARF63X350S
With 350 mm of travel and the highest thrust in the MA family, the MARF63X350S handles long push-and-pull jobs from a round stainless body: 1557.9 N forward and 1457.4 N back at 0.5 MPa, or 2181 N if you run 0.7 MPa. The flange you bolt to the machine is machined onto the front cover itself, so no loose mounting foot or adapter plate sits in the stack.
Long strokes punish unguided side load, so treat the 16 mm rod as a thrust member only and hang the load on external guides. Usable continuous force is about 935 N at 0.5 MPa once you stay at 60 percent of rating, which still hoists about 79 kg vertically with a 2:1 margin. Both ends carry a variable air cushion tuned by needle screws, letting a heavy load arrive at the end of 350 mm without hammering the cover.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MARF63X350S Is Used
Pallet-cage pusher on a roller spur
Drives a pusher plate that clears a loaded pallet cage off a roller spur in a distribution warehouse, 935 N of practical force at 0.5 MPa across the full 350 mm.
Return stroke on a materials test rig
Pulls a tensile sample grip back to its start position on a bench-top test machine, with the variable cushion decelerating the return so the grips are not jolted.
Cradle lift at a paint-mix station
Raises the pivot end of a mixing cradle about 300 mm; with the cradle counterweighted the cylinder sees under 79 kg, inside its vertical-lift margin.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X350S the Right Cylinder?
This sits in the longest standard stroke class of the range (up to 500 mm is available without custom order), so confirm air compressibility first: at 350 mm the air column is springy, and if supply drops the rod will sag because nothing in the cylinder locks position - a rod lock is the fix wherever hold is required. Lighter loads belong on the 50 mm bore with its 981 N push at 0.5 MPa; heavier work calls for a different cylinder family such as the MAC. The standard magnet with CMSG / DMSG / EMSG switches covers mid-stroke and end positions along the full length.
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 MARF63X350S FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181 N and pull 2040.3 N at 0.7 MPa; theoretical maximum 317.7 kgf at 1.0 MPa. The bore is 63 mm with a 16 mm rod, 1/4 inch ports, an M14x1.5 rod thread, and strokes up to 500 mm are standard.
Its barrel is stainless steel with aluminium covers rolled on, while the rod carries a 20 um hard-chrome plate - a combination that resists the rust and paint flaking you get on painted-steel mini cylinders in wet or outdoor areas. Hose the body down freely; just keep abrasive jets off the rod surface.
