Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 25mm 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 MAC63X25SCM
A 63 mm bore squeezed into a 25 mm stroke: the MAC63X25SCM is the round-end-cover version of AirTAC's cushioned MA mini line, double acting with an adjustable air cushion at both ends. Push is 1558 N and pull 1457 N at 0.5 MPa, and the CM cover presents a plain round boss that bolts to fixed plates or custom brackets.
The stainless tube and hard-chromed steel rod take damp, dust and light washdown better than painted minis, and air at 0.15-1.0 MPa (22-145 psi) drives the piston anywhere from 30 to 800 mm/s. Sizing is simple: count on about 935 N of usable push at 0.5 MPa rather than the full rating - roughly 79 kg lifted vertically with a 2:1 margin. Every piston carries its magnet as standard, ready for CMSG, DMSG or EMSG switching.

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 MAC63X25SCM Is Used
Locating pin eject
Kicks tapered locating pins out of a pallet fixture at the end of a machining cycle, with the cushion absorbing the release shock.
ICT test-nest eject
Pushes a finished PCB up and out of an in-circuit test nest so the pick-up arm can clear it without vacuum re-grip.
Chute diverter flip
Swings a sort chute between two collection totes on a small-parts conveyor, driven by the 25 mm stroke and 1558 N push.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X25SCM the Right Cylinder?
Compare before you buy: a 50 mm bore pushes 981 N at 0.5 MPa and suits lighter duty, while this 63 mm bore delivers 1558 N - the strongest the MA mini line reaches. At 0.7 MPa output climbs to 2181 N, which can let you raise line pressure instead of changing bore.
The CM round-end cover bolts straight to fixed plates; pick the CA pivot for link arms or the U flat end for a flat bracket, and add FA flange, LB foot or SDB pivot hardware if the layout needs it. Position is not retained when air is removed - the piston coasts freely - so pilot-check or rod-lock the unit for suspended or clamped holds. If the design later changes, the family covers it: MACD for a through rod, MACJ for an adjustable-cushion variant, MAR with an integrated mount.
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 MAC63X25SCM FAQ
Count on 1558 N pushing and 1457 N pulling at 0.5 MPa supply; at 0.7 MPa the numbers are 2181 N and 2040 N, and at the full 1.0 MPa the theoretical maximum is 317.7 kgf. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, double acting with adjustable cushioning at each end.
The round barrel is stainless steel and the 16 mm rod is carbon steel with a 20 um hard-chrome plating, so splash, mild corrosion and outdoor exposure are handled far better than painted mini cylinders; the aluminium covers are rolled and riveted onto the tube to keep the body sealed.
