Airtac MARF Stainless Steel Mini Air Cylinder MARF63X80S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X80S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 80mm 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 MARF63X80S
When an 80 mm throw has to carry the heaviest load in the series, the MARF63X80S brings the 63 mm bore with a push of 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa. It is double acting throughout, with a variable air cushion at each end and the front mounting bracket riveted into the cylinder body itself.
Because the covers, stainless block and barrel are rolled together into one sealed unit, the joint survives washdown better than bolted or painted minis - useful around food lines and outdoor gating. For sizing, treat about 935 N at 0.5 MPa as working push; vertically that is a 79 kg lift at a 2:1 margin. The magnet sits in the piston from the factory, so DMSG or EMSG switches mount with no special order.

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 MARF63X80S Is Used
Dock guard gate
Lifts a safety gate section at a loading dock; the integrated flange fixes straight to the guard post with no foot bracket.
Bale eject plate
Pushes compacted scrap off a small baler chamber over 80 mm, drawing on 2181.0 N available at 0.7 MPa.
Keg line stop
Stops kegs at a rinser infeed, where caustic splash rewards the stainless barrel and hard-chrome rod.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X80S the Right Cylinder?
Choose this 80 mm flanged bore when a 50 mm MA cylinder (981.3 N at 0.5 MPa) stalls under load but a larger platform is overkill - 63 mm is the series maximum. Without air the rod is free to move, so add a rod lock where a stopped mid-stroke must stay stopped. The M14x1.5 rod thread accepts I and Y knuckles; ports sit at 1/4 inch with PT, G or NPT threads.
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 MARF63X80S FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181.0 N push, 2040.3 N pull. Theoretical peak at 1.0 MPa is 317.7 kgf. Run it on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
Yes - every MA cylinder carries a piston magnet as standard, so CMSG, DMSG and EMSG reed switches clip onto the barrel and signal end positions without modifying the cylinder.
