Airtac MARU Stainless Steel Mini Cylinder MARU63X75S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X75S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MARU63X75S
Seventy-five millimetres of travel on the 63 mm bore makes the MARU63X75S a mid-short workhorse: 1557.9 N of push at 0.5 MPa, climbing to 2181.0 N at 0.7 MPa. Its riveted stainless barrel and hard-chrome 16 mm rod stand up to damp factory air, an edge painted minis tend to lose within a season.
The front bracket is integral in the up orientation, so no accessory flange or foot is needed. Run it on filtered air anywhere in the 0.15-1.0 MPa (22-145 psi) band. Working from the 0.5 MPa rating, expect about 935 N of honest force, good for lifting roughly 79 kg vertically at a 2:1 margin. Cushion needles at both ends let you tune the stop, and the standard magnet accepts CMSG, DMSG or EMSG switches out of the box.

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 MARU63X75S Is Used
Lid lift on a dough trough tipper
A bakery line uses the 75 mm stroke to pop trough lids before tipping; about 79 kg of vertical lift covers the heaviest lid.
Diverter flap at a grain elevator
1557.9 N at 0.5 MPa swings a heavy chute flap between silo lines, with the cushion damping each swing.
Curl ram on a sheet-metal brake
The short 75 mm beat applies 935 N of working force to curl small brackets at a fabrication bench.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X75S the Right Cylinder?
Between the 50 mm bore (981.3 N at 0.5 MPa) and nothing larger in the MAR line, this 63 mm bore is the ceiling on thrust - pick it when the 75 mm lift or press beat is fixed by your fixture. Air loss means drift, not hold: the cushion softens the stop but locks nothing, so add a rod lock where the load must stay put. Travel spans 30-800 mm/s, the ports are 1/4 inch, and the M14x1.5 rod thread carries I or Y knuckles for pivoting links.
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 MARU63X75S FAQ
At 0.5 MPa: 1557.9 N extend, 1457.4 N retract. At 0.7 MPa: 2181.0 N extend, 2040.3 N retract. Theoretical maximum at 1.0 MPa: 317.7 kgf. These come from the 63 mm bore with a 16 mm rod, 1/4 inch ports and a 75 mm stroke.
Needle screws at each end cover meter the exhaust in the last part of travel, slowing the piston before it lands. Adjust them on first run so the stop is soft rather than hammering; the cushion affects only stroke ends and is not a position lock.
