Airtac MARU Stainless Steel Mini Cylinder MARU63X300S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X300S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 300mm 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 MARU63X300S
1557.9 N of push and 1457.4 N of pull at 0.5 MPa put the MARU63X300S at the top of the MAR range - 63 mm is the biggest bore the series offers. This double-acting mini cylinder runs with a variable air cushion at both ends and carries its own up-mount front bracket, riveted straight onto the stainless round barrel, so no separate flange or foot is needed.
Working at a practical margin, that 0.5 MPa rating translates into roughly 935 N of usable push, enough to lift about 79 kg vertically on a 2:1 ratio. The hard-chrome plated 16 mm rod shrugs off mild corrosion and washdown, the grease-retaining piston seal stays lubricated over the 300 mm travel, and the standard magnet lets CMSG, DMSG or EMSG switches bolt on for end-of-stroke signalling.

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 MARU63X300S Is Used
Pallet Push-Off
Rolls reject pallets off the end of a beverage-warehouse conveyor; the 300 mm stroke clears a standard pallet width and about 935 N of working force does the shove.
Tote Lid Press on a Filling Line
Snaps lids onto wide washdown totes in a dairy, where the stainless barrel and chrome-plated rod stand up to daily hose-down.
Checkweigher Reject Pusher
Fires under-packed packs off a checkweigher belt in a meat-packing plant; 300 mm clears the reject lane and the variable cushions land the pack gently.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X300S the Right Cylinder?
If 1557.9 N at 0.5 MPa is more than the job needs, a 50 mm MAR delivers 981.3 N for less air consumption; 63 mm is the ceiling of the range. The MAR will not hold position on air loss - the piston drifts and the cushion only softens the stroke end - so fit a rod lock where a load must stay put. The integrated U bracket bolts to the frame, the built-in magnet suits CMSG or DMSG sensing, and I or Y knuckles thread onto the M14x1.5 rod. Keep the 300 mm rod free of side load to protect the bearing surfaces.
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 MARU63X300S FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa those rise to 2181.0 N push and 2040.3 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The U (up) front bracket is built into the cylinder - bolt it straight to the machine frame, no FA or foot accessory required. The piston magnet is fitted as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel for position feedback, and this bore uses 1/4 inch ports.
