Airtac MARU Stainless Steel Mini Cylinder MARU63X80S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X80S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 80mm 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 MARU63X80S
At the top of the MAR range, the AirTAC MARU63X80S pairs a 63 mm stainless round barrel with an 80 mm stroke and a factory-fitted up (top) mounting bracket, so the cylinder bolts straight onto your machine plate with no separate flange or foot to order. It is double acting with a variable air cushion at both ends: turn the needle screws in on first run and end-of-stroke shock stays under control even at the full 30-800 mm/s speed band.
This bore delivers 1558 N of push and 1457 N of pull at 0.5 MPa, and 2181 N of push at 0.7 MPa. Theoretically that is about 158 kg of vertical lift at 0.5 MPa, so for a 2:1 margin plan on lifting around 79 kg per cylinder. The riveted stainless-steel tube and hard-chrome plated rod (20 um) tolerate washdown and damp plant air far better than painted minis, and the magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on 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 MARU63X80S Is Used
Stamping die clamp
Clamping die halves or bolster plates on a 60-ton press: 1558 N at 0.5 MPa holds heavy tool steel, and the variable cushion takes the clang out of every clamp cycle.
Pallet stopper lift
Raising and lowering stop blades on a warehouse pallet conveyor, where the 63 mm bore lifts parts of roughly 79 kg with a 2:1 margin and the stainless barrel copes with washdown.
Case packer ejector
Kicking filled cartons off a food-line transfer conveyor; the up-mount bracket fixes directly to the frame top and the built-in magnet feeds a CMSG switch for end-of-stroke confirmation.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X80S the Right Cylinder?
Sizing down a step, the 50 mm MAR gives 981 N of push at 0.5 MPa; at 63 mm you get the largest bore the series offers, so if 1558 N is still short of your need you must move to a different AirTAC family. Remember the MAR does not hold position on air loss: the piston drifts, the cushion only softens the stroke end, so add a rod lock where a load must stay put. Mounting is via the integrated up bracket only (no FA, LB or SDB accessories on MAR), while I and Y rod knuckles still thread onto the M14x1.5 rod. The 80 mm stroke is a standard length; strokes up to 500 mm exist for this bore, and longer travels raise side-load risk on the 16 mm rod, so guide the load externally.
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 MARU63X80S FAQ
At 0.5 MPa it pushes with 1558 N and pulls with 1457 N; at 0.7 MPa those rise to 2181 N push and 2040 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, air filtered to 40 um, and the bore is 63 mm with an 80 mm stroke.
The rolled stainless-steel barrel and hard-chrome plated rod resist corrosion in wet, food or outdoor areas where painted mini cylinders flake, and the riveted covers keep the joint sealed without tie rods. Yes, set the cushion on commissioning: adjust the needle screws at both ends until the 63 mm piston lands quietly across the 30-800 mm/s speed range.
