Airtac MARF Stainless Steel Mini Air Cylinder MARF63X500S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X500S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 500mm 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 MARF63X500S
Five hundred millimetres is the longest standard stroke in the MAR series, and the MARF63X500S pairs that reach with the strongest force the line offers: 1558 N pushing at 0.5 MPa, 2181 N at 0.7 MPa, and a 317.7 kgf theoretical maximum. The double-acting body carries a variable cushion at each end and its own front flange, rolled into the aluminium cover, so mounting needs no added bracket. The stainless tube and 20 um hard-chrome plated 16 mm rod hold up in humid plants, and a magnet is fitted to the piston as standard for CMSG / DMSG / EMSG switches.
At 0.15-1.0 MPa (22-145 psi) and speeds of 30-800 mm/s, keep the working load near 935 N - that is 60 percent of the push rating - or think of it as lifting about 79 kg vertically with a 2:1 safety margin. With retract force of 1457 N at 0.5 MPa, even a heavy slide returns without hesitation.

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 MARF63X500S Is Used
Paint Booth Door Actuator
A 500 mm stroke raises a lightweight booth access door of about 70 kg; flange mounting near the hinge keeps the load path straight down the rod.
Transfer Car Push on a Track
Shunting a 250 kg die cart along a flat track takes well under the 1558 N available; the cushion brings the car to a gentle stop against the end stop.
Bin Discharge Gate
Opening a slide gate on a powder hopper: the rod retracts with 1457 N at 0.5 MPa, enough to shear the powder column even after a shift of settled material.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X500S the Right Cylinder?
At this length, rod stiffness is the real design constraint: support the load in its own guides and avoid cantilevered side loads, since a 16 mm rod over 500 mm of unsupported travel will flex under abuse. For lighter jobs the MARF50X500S gives 981 N at 0.5 MPa behind a smaller flange; for more than 1558 N, raise the supply toward 0.7 MPa (2181 N) - 63 mm is the largest bore this series comes in.
Remember the piston is free to move whenever air pressure drops, so anything that must stay extended between cycles needs a rod lock, a control circuit with positive stops, or a mechanical latch - the MAR itself provides none of these.
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 MARF63X500S FAQ
Extend force is 1558 N and retract force 1457 N at 0.5 MPa; at 0.7 MPa these rise to 2181 N and 2040 N, with a theoretical maximum of 317.7 kgf at 1.0 MPa. The cylinder is double acting and cushioned at both stroke ends.
Both ends have adjustable cushion needles. On start-up, run the rod slowly into each end, then close the needles until the load decelerates smoothly instead of hitting the cover - on a 500 mm stroke this matters most when the rod carries a heavy slide near the 935 N working figure. Speeds up to 800 mm/s are fine once cushioning is dialed in.
