Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 400mm 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 MAC63X400SCA
Long travel and heavy thrust meet in the MAC63X400SCA: 400 mm of stroke from a bore that pushes 1558 N and pulls 1457 N at 0.5 MPa, or 2181 N at 0.7 MPa. At a 2:1 margin that means roughly 79 kg can be lifted vertically, a figure worth checking against your load before ordering.
The riveted stainless round barrel and hard-chrome plated 16 mm rod take spray, humidity and outdoor weather far better than painted minis. Air acts on both faces - it is double acting, with a variable cushion bleeding off shock at each end - and the standard built-in magnet supports CMSG / DMSG / EMSG switches. CA pivot rear cover, 1/4-inch port, M14x1.5 rod thread.

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 MAC63X400SCA Is Used
Carton reject pusher
Sweeps rejected cartons off a case conveyor across a 400 mm lane; the long stroke clears the full belt width in one move.
Oven damper swing
Swings a large bake-oven air damper open and closed through its pivot linkage, with the cushion easing the seat at each end.
Bar feed index
Advances bar stock the final 400 mm into a lathe collet on an automated bar feeder.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X400SCA the Right Cylinder?
Downsizing: the 50 mm bore yields 981 N push at 0.5 MPa for lighter gates, and nothing in the MAC line out-thrusts this 63 mm barrel. Over a 400 mm stroke, side load is the rod's enemy - carry the load on external guides and keep the push axis aligned, or rod bending will shorten seal life. The CA pivot suits swing links and SDB pivot brackets; FA flange or LB foot suit fixed frames. If the stroke must hold under a dropped air supply, fit a rod lock - cushioning is not a brake.
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 MAC63X400SCA FAQ
1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a theoretical 318 kgf peak at 1.0 MPa. Rated speed is 30-800 mm/s across the 400 mm stroke.
No. The variable air cushion only softens end-of-stroke impact; with the valve centred the piston drifts freely. For loads that must stay extended, add a rod lock or a pilot check valve in the line.
