Airtac MARF Stainless Steel Mini Air Cylinder MARF63X250S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X250S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 250mm 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 MARF63X250S
At 250 mm, the MARF63X250S stretches AirTAC's cushioned round-body mini to a quarter metre while keeping the 63 mm force class intact: 1557.9 N push, 1457.4 N pull at 0.5 MPa (72.5 psi), and 2181.0 N push once you run 0.7 MPa. As the stroke stays under the bore's 500 mm standard ceiling, this length is a stock configuration. Mounting is built in - the F cover carries the front flange, eliminating separate bracket hardware.
Two details make this cylinder easy to live with. First, the stainless barrel and 20 um chrome-plated rod tolerate humidity, mild chemicals and outdoor exposure that would chew painted minis. Second, the magnet is fitted as standard, so CMSG / DMSG / EMSG switches read end positions from day one. For vertical work, halving the 158.8 kgf equivalent of the 0.5 MPa push leaves about 79 kg of comfortable lifting capacity per unit.

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 MARF63X250S Is Used
Feed mill slide gate
Opens and closes a slide gate under a pellet cooler hopper; 1557.9 N at 0.5 MPa shears a column of feed and the variable cushion stops the gate without bang.
Shrimp processing pusher
Pushes trays through an ice-glazing tunnel on repeat cycles; salt-laden spray around the stainless barrel and chrome rod causes no rust creep.
Textile beam doffer
Lowers full yarn beams off a winding frame; about 79 kg of vertical lift per cylinder handles the beam weight with a 2:1 margin built in.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X250S the Right Cylinder?
Downsize to the 50 mm bore and you give up 576 N of push (981.3 N versus 1557.9 N at 0.5 MPa); upsize and you are out of MAR territory - the 63 mm bore is the range ceiling, with MAC or MACD variants available where separate mounts or a double rod are needed. This 250 mm stroke remains within the 500 mm standard catalogue limit.
For a job that must stay put during a power or air failure, this cylinder alone is the wrong tool: the piston drifts when pressure drops, and only a separate rod lock provides holding. At a quarter-metre stroke, alignment matters more than column strength; guide the load so bending moment never reaches the M14x1.5 threaded end.
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 MARF63X250S FAQ
Expect 1557.9 N of push and 1457.4 N of pull at 0.5 MPa (72.5 psi), 2181.0 N of push at 0.7 MPa, and 317.7 kgf theoretical at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof, and strokes at 30-800 mm/s between -20 and +70 C.
The piston magnet is a standard fitting, not a paid option, so AirTAC CMSG, DMSG or EMSG switches mount directly on the stainless barrel for end-of-stroke signalling without modifying the cylinder.
