Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 30mm 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 MAC63X30SCM
Built for hard, repetitive clamping, the MAC63X30SCM combines a 63 mm bore, 30 mm stroke and a CA pivot back cover in AirTAC's riveted round-body mini. Double acting with a variable air cushion at both ends, it generates 1557.9 N of push and 1457.4 N of pull at 0.5 MPa (72 psi), peaking at 317.7 kgf theoretically at 1.0 MPa. Supply pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
Two practical notes for specifiers. First, plan the duty around about 935 N of usable force at 0.5 MPa rather than the peak figure - and vertically that means lifting roughly 79 kg with a 2:1 margin. Second, the body is a stainless-steel tube rolled tight against aluminium covers with a grease-retaining two-way piston seal, so it keeps running in grinding dust, coolants and outdoor rain where coated minis rust. The magnet is part of the standard build, and CMSG, DMSG or EMSG switches confirm clamp state on every cycle.

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 MAC63X30SCM Is Used
Weldment clamp bank
A row of these clamps grips steel chassis parts on a robotic welding line; the pivot cover follows each clamp linkage and the magnet feeds clamp-state signals to the PLC.
Mould core interlock
Locks a sliding core in a small injection mould, where 935 N of working force at 0.5 MPa resists melt back-pressure over a 30 mm travel.
Bottle lane reject finger
Flicks rejected containers off a bottling conveyor, with the cushion damping thousands of fast snaps per shift in a wet, rinsed environment.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SCM the Right Cylinder?
Nothing in the MA series out-pushes this bore: at 1558 N push at 0.5 MPa it is the range maximum, while the 50 mm bore at 981 N covers lighter clamps more economically. The 30 mm stroke sits well inside the 500 mm standard limit. One caution for fixture designers: the cushion tunes the end stop but is not a brake - if the clamp must stay closed on air loss, fit a pilot check valve or move up to a rod lock arrangement.
The CA pivot end suits linkage-driven clamps directly; the U flat-end and CM round-end covers, plus FA flange, LB foot and SDB pivot brackets, convert the same cylinder to fixed mounting. Ports are 1/4" and the 16 mm rod carries an M14x1.5 thread for standard knuckle joints (I or Y type).
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.

Unlike painted or extruded-aluminium minis that pit and jam after washdowns, this cylinder uses a stainless-steel barrel riveted to aluminium covers with a hard-chrome plated rod - so coolant splash, salt air and outdoor rain barely touch it. The two-way piston seal also stores grease inside, extending service intervals in dusty grinding or foundry air.
