Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 140mm 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 MAC Stainless Steel Mini Air Cylinder MAC63X140SU
A 63 mm bore in a stainless round body gives MAC63X140SU serious push: 1558 N at 0.5 MPa (73 psi) over a 140 mm stroke, with air driving the rod both out and back and a variable air cushion at each end to take the shock out of arrival. Being the largest MA bore, it tops the family force chart at a theoretical 317.7 kgf from 1.0 MPa (145 psi).
The barrel is stainless steel, the 16 mm rod is carbon steel hard-chrome plated to 20 um, and the aluminium-alloy covers plus a stainless block are rolled onto the tube, so the sealed round body shakes off washdown and damp shop air. A magnet is built in from the factory, so CMSG, DMSG or EMSG switches clamp on with no special-order piston. For planning, treat about 935 N as the true working push at 0.5 MPa - roughly 79 kg lifted vertically once a 2:1 margin is applied.

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 MAC Stainless Steel Mini Air Cylinder MAC63X140SU Is Used
Casting-lid lift on a die-cast cell
Raising a 60 kg aluminium die cover through 140 mm, with the cushion damping the drop onto the stop and a DMSG switch confirming the open position.
Bushings pressed into pump housings
The 1558 N push at 0.5 MPa seats bronze bushings in a maintenance press; 0.7 MPa air adds margin for tighter interference fits.
Roller-conveyor gating in a bottling hall
Pushing a gate across a 140 mm lane of bottles where washdown spray would chew a painted mini cylinder - the stainless barrel and chrome rod tolerate it.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SU the Right Cylinder?
Size it against its neighbour: the 50 mm bore pushes 981 N at 0.5 MPa, so if your load sits under 900 N that smaller cylinder saves air; 63 mm is the ceiling of the range, so gain force from pressure (2181 N at 0.7 MPa) rather than bore size. Note the cylinder does not hold position when air is removed - fit a rod lock or pilot check valve if the load must stay put with power off. The U flat-end back cover bolts to a fixed plate or bracket directly; add FA flange, LB foot or SDB pivot mounts and I or Y rod knuckles as the machine layout demands. On a 140 mm stroke with a 16 mm rod, keep side loads low and guide the payload externally to protect the rod bearings.
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 MAC Stainless Steel Mini Air Cylinder MAC63X140SU FAQ
At 0.5 MPa it pushes 1558 N and pulls 1457 N; at 0.7 MPa those figures rise to 2181 N and 2040 N. The theoretical maximum at 1.0 MPa is 317.7 kgf. Ports are 1/4", the rod is 16 mm with an M14x1.5 male thread, and the cushion is adjustable at both ends.
The U cover finishes the cylinder in a flat face with fixing holes, so it mounts straight onto a machine plate without an intermediate bracket. Every MAC cylinder includes a piston magnet as standard, letting CMSG, DMSG or EMSG reed switches signal end positions along the 140 mm stroke.
