Airtac MARU Stainless Steel Mini Cylinder MARU63X150S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X150S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 150mm 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 MARU63X150S
Built around its own front bracket, the MARU63X150S mounts up-top with no auxiliary flange or foot to order - the U bracket is rolled in as part of the body. The stainless round tube resists corrosion in wet or dusty plants, and the hard-chromed rod carries a 20 um plating that survives abrasive dust. Every unit ships with the position magnet already fitted.
Push force at 0.5 MPa is 1558 N against a 1457 N pull, rising to 317.7 kgf theoretical at the full 1.0 MPa supply. That is about 935 N of dependable working force once you keep 40% in reserve. The variable air cushion at both ends of the 150 mm stroke soaks up landing shock, so hopper gates and pushers can cycle fast without shaking the frame.

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 MARU63X150S Is Used
Hopper bin gate
Opens a slide gate under a warehouse ingredient hopper; 1558 N at 0.5 MPa shears compacted powder while the 150 mm stroke clears the outlet.
Recycling bale door
Swings the ejection door on a small waste-bale press, where the variable cushion catches the door weight at the end of each 150 mm swing.
Paper roll pusher
Pushes paper rolls off a slitting table onto a take-off conveyor; the chromed rod shrugs off paper dust across continuous shifts.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X150S the Right Cylinder?
Because 63 mm is already the biggest MAR bore, compare downward: 50 mm gives 981 N and 32 mm gives 402 N at 0.5 MPa, so choose the smaller bores when the duty is light. Position is not held on air failure - the rod follows any back-load - so pair the cylinder with a rod lock where the gate must stay put. Sensor feedback is simple: the standard magnet drives CMSG, DMSG or EMSG switches anywhere along the 150 mm stroke.
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 MARU63X150S FAQ
At 0.5 MPa: 1557.9 N extending, 1457.4 N retracting. At 0.7 MPa: 2181.0 N extending, 2040.3 N retracting. Theoretical maximum 317.7 kgf at 1.0 MPa. Bore 63 mm, rod 16 mm with M14x1.5 male thread, ports 1/4 in.
Yes, without special ordering. The magnet is built into the piston as standard equipment on this series, so CMSG, DMSG and EMSG switches mount directly on the barrel and read end or mid positions across the 150 mm travel, while the cylinder runs 0.15-1.0 MPa (22-145 psi).
