Airtac MARU Stainless Steel Mini Cylinder MARU63X110S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU63X110S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø63mm bore and 110mm 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 MARU63X110S
The MARU63X110S pairs a riveted stainless round barrel with a hard-chromed 16 mm rod, so mild corrosion and washdown hit far less hard than on painted-steel minis. Air works both sides of the piston: double acting, with a variable cushion at each end that you needle-adjust on first run. The U top bracket is part of the front cover, so the cylinder bolts straight to the machine with no separate foot.
At 0.5 MPa this 63 mm bore pushes 1558 N and pulls 1457 N, with a theoretical 317.7 kgf ceiling at 1.0 MPa. Because the cushions absorb end-of-stroke shock, you can cycle faster or carry heavier loads without hammering the covers. Plan on roughly 935 N of real work at 0.5 MPa, about 60% of the push rating, to keep a comfortable margin.

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 MARU63X110S Is Used
Bottling tray ejection
Fills a push-out station that clears filled trays from a bottling conveyor; 1558 N at 0.5 MPa moves loaded trays without stalling over the 110 mm travel.
CNC drill clamp
Clamps gear blanks in a drilling fixture, holding roughly 935 N of practical clamp force per unit at 0.5 MPa while the tool cycles.
Dairy pail lid press
Presses lids onto dairy pails; the variable cushion eases the ram down so the 110 mm stroke does not crack the rim at speed.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU63X110S the Right Cylinder?
63 mm is the top of the MAR range, so you only size down: at the same 0.5 MPa a 50 mm bore gives 981 N push and a 40 mm bore 628 N, so stay at 63 only if your jig needs the full 1558 N. Note that this is not a position holder - if air pressure drops the rod drifts with the load, so add a rod lock when a part must stay put. The built-in magnet accepts CMSG, DMSG or EMSG switches, and the 110 mm stroke on a 16 mm rod calls for clean alignment; fit an external guide if the load is offset.
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 MARU63X110S FAQ
Double-acting figures for the 63 mm bore: 1557.9 N push and 1457.4 N pull at 0.5 MPa; 2181.0 N push and 2040.3 N pull at 0.7 MPa; theoretical maximum 317.7 kgf at 1.0 MPa. Air ports are 1/4 in and the rod is 16 mm with an M14x1.5 male thread.
The rolled stainless tube plus the 20 um hard-chrome rod shrug off damp air, washdown splash and outdoor weather that pit painted or plain aluminium bodies. The cylinder runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and the cushion screws at both ends let you tune the landing for each application.
