Airtac MARU Stainless Steel Mini Cylinder MARU63X350S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X350S is a genuine double acting + cushion (up 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 MARU Stainless Steel Mini Cylinder MARU63X350S
A riveted stainless round barrel with an up-mount bracket already rolled into it - the MARU63X350S arrives ready to bolt down with no separate flange. Behind the 350 mm stroke sits a 63 mm piston pushing 1557.9 N and pulling 1457.4 N at 0.5 MPa, double acting with variable air cushions at both ends.
Size the job honestly: about 935 N of that rating is a sensible working force, which lifts roughly 79 kg vertically on a 2:1 margin. Over 350 mm of travel the hard-chrome 16 mm rod benefits from clean alignment and minimal side load; the grease-retaining two-way seal keeps it lubricated, and the built-in magnet accepts CMSG, DMSG or EMSG switches anywhere along the barrel.

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 MARU Stainless Steel Mini Cylinder MARU63X350S Is Used
Sluice Gate on a Water-Treatment Skid
Raises and lowers a small sluice gate by 350 mm; the stainless barrel shrugs off the constant damp around clarifier tanks.
Case Layer Pusher in a Bottling Plant
Squares and pushes a completed 350 mm-tall layer of cartons onto a stacking table, with cushions easing the layer into place.
Vertical Lift on a Paint-Line Carrier
Hoists a small hanger carrier 350 mm between conveyor rails; add a rod lock if the carrier must keep hanging when air pressure drops.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X350S the Right Cylinder?
A 50 mm MAR (981.3 N push at 0.5 MPa) suits lighter 350 mm jobs; nothing above 63 mm exists in this series. For holding a raised load through air loss, the MAR alone will not do it - the piston drifts, so spec a rod lock. Mounting is the integrated U bracket only, DMSG switches read end positions off the standard magnet, and I or Y rod knuckles fit the M14x1.5 thread. Run the cushion needles in gently on the first strokes to tame the long travel.
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 MARU Stainless Steel Mini Cylinder MARU63X350S FAQ
Push is 1557.9 N and pull 1457.4 N at 0.5 MPa. At 0.7 MPa expect 2181.0 N push and 2040.3 N pull, with a theoretical ceiling of 317.7 kgf at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi), the working band is 0.15-1.0 MPa (22-145 psi) and speed range is 30-800 mm/s.
Yes - MAR bores accept strokes up to 500 mm as standard, so 350 mm ships without custom ordering. Fixing is by the front-cover up (U) bracket that forms part of the rolling-packed body; no foot or separate flange is used. The piston magnet is standard, so CMSG or EMSG switches drop on for feedback.
