Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 70mm 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 MAC63X70SU
Flat-ended and fixed-mount friendly, this 63 mm cylinder pushes 1558 N at 0.5 MPa - nearly 60% more than a 50 mm bore of the same family - in a compact round body. For sizing, reserve about 935 N of that push for real work, which lifts roughly 79 kg vertically at a 2:1 margin. The stainless tube and hard-chrome plated rod survive splashes and outdoor humidity that pit painted-steel minis within months.
Both stroke ends carry a variable air cushion, so a 70 mm move can finish gently even near 800 mm/s. Since the piston is double acting but never locked, a power cut lets the load drift; where a lid or gate must hold, pair the cylinder with a rod lock or pilot check valve. A magnet ships built in, so position signals via CMSG / DMSG / EMSG switches need no 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 MAC Stainless Steel Mini Air Cylinder MAC63X70SU Is Used
Reactor sampler in a chemical plant
The stainless barrel and chrome rod shrug off splash near rinse stations while 1558 N drives the probe into the vessel port.
Pallet stop at a dock leveller
The flat-end cover face-mounts to the stop frame, arresting pallets with cushions easing the final contact.
Case squarer on a carton sealer
Squares leaning cartons before taping; about 935 N of practical force straightens a full case without crushing flaps.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SU the Right Cylinder?
The U flat-end back cover bolts flush against a machine face, and LB foot, FA flange or SDB pivot brackets cover the remaining mounting cases. Ports are 1/4" and the 16 mm rod carries an M14x1.5 male thread.
If 1558 N exceeds the job, the 32 mm bore pushes 402 N at 0.5 MPa; for demands beyond 317.7 kgf theoretical, move to a larger cylinder family. Working pressure is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
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 MAC63X70SU FAQ
Expect 1557.9 N push and 1457.4 N pull at 0.5 MPa, rising to 2181.0 N push and 2040.3 N pull at 0.7 MPa; theoretical peak is 317.7 kgf at 1.0 MPa. Stroke is 70 mm with a 16 mm rod threaded M14x1.5 and 1/4" ports.
The U flat end presents a flat machined face that bolts straight to a fixed frame, avoiding bracket stacks. Add FA flange, LB foot or SDB pivot hardware only where the machine layout calls for it.
