Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SU 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 MAC63X30SU
A 30 mm stroke on the largest MA-series bore makes the MAC63X30SU a compact puncher for short-travel, high-force jobs: double acting, with a variable air cushion at each end to dial out impact. At 0.5 MPa the 63 mm piston throws 1557.9 N on extend and 1457.4 N on retract, rising past 2181 N at 0.7 MPa - a 317.7 kgf theoretical ceiling at 1.0 MPa.
The riveted round body pairs a stainless-steel barrel with a 20 um hard-chrome plated rod, so it tolerates washdown and humid plant air far better than painted minis. Keep real duty near 935 N at 0.5 MPa and the rod will vertically lift about 79 kg with a 2:1 margin. Operating envelope is 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, and the magnet is fitted as standard for CMSG, DMSG and 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 MAC63X30SU Is Used
Batch-code stamping die
Drives a steel stamp into aluminium castings on a short-strike press, with about 935 N of usable force at 0.5 MPa.
Weld fixture clamp
Clamps a car-door bracket against a hard stop before robotic welding; the 30 mm stroke cycles at up to 800 mm/s.
Bearing press-in head
Seats small bearings into pump housings, the flat U back cover bolted directly to the press crosshead.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X30SU the Right Cylinder?
Downsize check first: a 50 mm bore still gives 981.3 N push at 0.5 MPa, and there is nothing larger than 63 mm in this series, so this is the top force class. The U flat-end back cover bolts square to a machine face without pivot hardware; FA flange, LB foot or SDB bracket mount separately if needed. Note that with air removed the rod simply drifts - the cushion damps motion, it never locks it, so fit a rod lock or pilot check valve to hold a load.
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 MAC63X30SU FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181.0 N push, 2040.3 N pull. Theoretical maximum is 317.7 kgf at 1.0 MPa. Air feeds through the 1/4" port and the male rod thread is M14x1.5.
The U flat-end cover gives a rigid, flat fixing face for direct bolting - handy on press heads and clamps where no pivot is wanted. Run the cushion needle screws fully open on first start-up, then close them gradually for a soft stop. The standard magnet accepts CMSG / DMSG / EMSG switches without any special-order piston.
