Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCA 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 MAC63X70SCA
Biggest bore in the MAC family, the 63 mm barrel turns 0.5 MPa shop air into 1558 N of push and 1457 N of pull, so one compact round body can replace a much bulkier frame cylinder. The stainless-steel barrel and hard-chrome plated 16 mm rod shrug off washdown and damp plant air that ruins painted minis, while the riveted aluminium covers keep the joint sealed.
At the end of each stroke a variable air cushion soaks up the shock, letting you push heavier loads faster without hammering the covers. Plan on roughly 935 N of usable force at 0.5 MPa rather than the full 1558 N rating - in vertical terms that is about 79 kg lifted with a 2:1 margin. A magnet comes built in as standard, so CMSG / DMSG / EMSG switches clip straight on.

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 MAC63X70SCA Is Used
Crate pusher on a bottling line
The 1558 N push slides a full beverage crate along a conveyor lane, with cushions softening the stop at the lane end.
Clamp fixture on a welding table
The pivoting CA mount follows fixture arm motion; about 935 N of practical clamp force holds steel sheet through tack welding.
Lid press on a drum filling station
A 70 mm stroke seats drum lids evenly, and the 1/4" ports keep flow high on the fast approach.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCA the Right Cylinder?
Need less force? The 50 mm bore pushes 981 N at 0.5 MPa; there is no larger bore above 63 mm in this series, so if 1558 N is not enough step up to a bigger cylinder family. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The CA pivot back cover on this variant takes a pivoting load directly, and FA flange, LB foot or SDB pivot brackets bolt on when the frame needs them. Ports are 1/4" and the piston drifts if air is lost - fit a rod lock or pilot check valve where a load must stay put.
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 MAC63X70SCA FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 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. Stroke is 70 mm, the rod is 16 mm with M14x1.5 male thread, and ports are 1/4".
Back both cushion needle screws off before the first run, then close them gradually until the 70 mm stroke ends land without bounce; speed range is 30-800 mm/s. The built-in magnet is standard, so CMSG, DMSG or EMSG switches mount on the barrel without ordering a special piston.
