Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCM 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 MAC63X70SCM
With 2181 N of push available at 0.7 MPa, this 63 mm mini cylinder handles loads that stall a 50 mm bore (981 N at 0.5 MPa) outright. Its round stainless barrel resists mild corrosion in damp or outdoor air, and the rolled, riveted cover-to-barrel joint keeps the seal tight for years.
The CM round-end back cover accepts a clevis pin directly, so the cylinder can follow a swinging lever or flap without improvised brackets. Because air drives the rod both ways, the piston will drift if supply pressure drops - add a pilot check valve or rod lock whenever a raised load must stay parked. Count on about 935 N of real working force at 0.5 MPa, enough to lift roughly 79 kg vertically with a 2:1 margin. A magnet is installed as standard for CMSG / DMSG / EMSG switches.

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 MAC63X70SCM Is Used
Sluice flap on a powder hopper
The round-end cover pivots the discharge flap open against 1457 N of pull force as powder floods the bagging station.
Die cart indexer
Pushes a die cart 70 mm onto its mechanical stop; the cushions absorb the impact of the cart arriving at speed.
Mixing drum tilt on a pilot line
A clevis-pivoted tilt frame lifts about 79 kg of drum and contents with a 2:1 safety margin at 0.5 MPa.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X70SCM the Right Cylinder?
Choose this model when the load pivots: the CM round end plus an I or Y rod knuckle forms a clean clevis joint. If the application is rigid and fixed instead, the U flat-end variant or an FA flange fits better. Pressure runs 0.15-1.0 MPa (22-145 psi).
A 16 mm hard-chrome rod on a 70 mm stroke tolerates moderate side loads, but keep external guides close to the rod on long overhangs. Ports are 1/4".
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 MAC63X70SCM FAQ
At 0.5 MPa the piston pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa that becomes 2181.0 N push and 2040.3 N pull, topping out at 317.7 kgf theoretical force at 1.0 MPa. The bore runs double acting with a variable air cushion at each end.
The CM back cover takes a clevis pin straight into the housing, so swinging links and flaps mount without extra brackets. Combined with the stainless barrel and chrome-plated rod, it suits wash-prone corners like hopper discharges and rinse stations.
