Airtac MARU Stainless Steel Mini Cylinder MARU63X30S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X30S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 30mm 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 MARU63X30S
Short on travel, heavy on muscle: with just 30 mm of stroke the MARU63X30S still pushes 1557.9 N and pulls 1457.4 N at 0.5 MPa, the strongest output AirTAC's MAR series makes. Double acting with variable air cushions at each end, this 63 mm round-body cylinder carries an integrated up-mount bracket rolled onto its stainless barrel.
Keep the working force near 935 N for long seal life, or read it another way: about 79 kg of vertical lift with a 2:1 margin. Over such a short stroke the cushion needles do most of the tuning - set them on first run so fast 30 mm snaps do not hammer the aluminium covers. The built-in magnet feeds CMSG, DMSG or EMSG switches without any special-order piston.

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 MARU63X30S Is Used
CNC Fixture Clamp
Clamps a cast-iron workpiece in a machining jig; 30 mm is all the clearance a top clamp needs and about 935 N of working force holds it against cutter lift.
Crimp Head on Cable Benches
Drives a small crimp die on wire-harness assembly benches - the short throw keeps cycle time under a second at 800 mm/s.
Part Ejector in a Forming Die
Kicks finished stamped parts out of the die pocket with a quick 30 mm kick, cushioned so the die face is not hammered at each stroke.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X30S the Right Cylinder?
For a lighter short-stroke clamp, a 50 mm MAR gives 981.3 N at 0.5 MPa in the same round-body style; 63 mm is the largest bore available. If the load must stay clamped through a power cut, remember the MAR drifts on air loss - the cushion softens travel but holds nothing - so pair it with a rod lock. The up-mount face bolts directly to the jig, the built-in magnet works with EMSG switches for clamped/unclamped signals, and I or Y knuckles still fit the M14x1.5 thread.
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 MARU63X30S FAQ
At 0.5 MPa: 1557.9 N push and 1457.4 N pull. At 0.7 MPa: 2181.0 N push and 2040.3 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. It runs on filtered air at 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s.
You keep the full 1557.9 N output while trimming the envelope and cycle time. Variable cushions at both ends absorb the shock of fast short travel, the stainless round barrel resists damp and mild washdown, and the standard magnet works with CMSG, DMSG or EMSG switches for precise end-position signals.
