Airtac MARU Stainless Steel Mini Cylinder MARU63X450S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X450S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 450mm 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 MARU63X450S
A 450 mm stroke on the biggest MA bore gives the MARU63X450S real muscle: 1557.9 N of push at 0.5 MPa and 2181.0 N at 0.7 MPa, all from a round stainless-steel barrel with the up bracket rolled into its riveted covers. Because the cylinder carries its own front flange, there is no separate mounting accessory to order or align. The variable cushion at each end lets you trim end-of-stroke shock, so a heavy load can arrive fast without hammering the aluminium covers.
In practice, plan on about 935 N of usable force at 0.5 MPa - roughly 79 kg lifted vertically with a 2:1 margin. Every unit ships with the magnet fitted as standard, so CMSG, DMSG or EMSG switches click on for end-of-stroke signalling, and the hard-chrome plated 16 mm rod plus 1/4 inch ports keep plumbing simple in damp washdown corners.

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 MARU63X450S Is Used
Crate pusher on a bottling line
The 450 mm throw slides glass crates across a chain conveyor at a brewery, with the cushioned stop protecting the guide rail.
Bale ejector in a cardboard baler
Push force of 1557.9 N at 0.5 MPa kicks compacted bales off the press plate once the chamber is full.
Sluice gate drive at a wastewater plant
With about 79 kg of vertical lift capacity at a 2:1 margin, the cylinder raises a small channel gate on demand.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X450S the Right Cylinder?
At 63 mm this is the top of the MAR range - the next bore down, 50 mm, delivers 981.3 N push at 0.5 MPa, so step down only if your load works comfortably under about 589 N. For a 450 mm stroke, keep side loads off the rod and guide the load in its own bearings; the hardened 16 mm rod carries thrust, not bending. Air supply can sit anywhere in the 0.15-1.0 MPa (22-145 psi) band, with travel from 30 to 800 mm/s.
Like any plain double-acting cylinder it will drift rather than lock when air pressure is lost - add a rod lock if the load must stay put. The up bracket bolts straight to the machine frame, and I or Y rod knuckles still fit the M14x1.5 male 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 MARU63X450S FAQ
At 0.5 MPa it pushes with 1557.9 N and pulls with 1457.4 N. At 0.7 MPa the figures rise to 2181.0 N push and 2040.3 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. The 63 mm bore drives a 16 mm rod through 1/4 inch ports, and the 450 mm stroke sits inside the 500 mm standard limit.
Yes. Turn the needle screws at both end covers until the piston decelerates smoothly instead of hitting the covers hard. The cushion only softens the last of the stroke at speeds up to 800 mm/s - it does not hold the rod in place if air is lost.
