Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 125mm 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 MAC63X125SU
Pull force is where this cylinder earns its keep: 1457.4 N of retraction at 0.5 MPa on a 63 mm bore, housed in a rolled stainless barrel with 1/4" ports that copes with damp and washdown corners far better than painted-steel minis. Double acting throughout, it sweeps its 125 mm stroke at 30-800 mm/s and carries a variable air cushion at each end so the covers never take a beating.
Push side, expect 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa. Budget about 874 N of pull for continuous duty - roughly two thirds of rating - and the SU flat-end back cover will take a fixed plate mount without adapter brackets. The piston magnet comes standard, so a CMSG or EMSG switch drops straight onto the tube for end-of-stroke signalling.

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 MAC63X125SU Is Used
Core-knockout bench
Knocks sand cores loose in a foundry knockout rig; 874 N of dependable pull snaps cores free of their prints while the stainless barrel tolerates foundry dust and humidity.
Crate lane diverter
Pushes stacked cartons from a picking lane onto a takeaway belt; the 125 mm stroke spans two roller pitches and the cushion lets the line run at full belt speed without jolts.
Clamp fixture actuator
Clamps steel weldment jigs shut on a fabrication bench, where the U flat-end cover bolts flush to the fixture plate and the built-in magnet signals clamp-made to the PLC.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X125SU the Right Cylinder?
Measured against the 50 mm bore (981.3 N push at 0.5 MPa), this 63 mm unit gives over half as much force again, and it is the ceiling of the MAC cushioned line, so going larger means changing families. Because a vented MAC piston drifts freely - the cushion is a shock absorber, never a lock - fit a pilot check valve or rod lock wherever the load must hold position. Foot (LB), flange (FA) and pivot (SDB) brackets all bolt to the standard body, and the flat-end SU cover suits direct plate bolting on machine frames.
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 MAC63X125SU FAQ
Figures for this 63 mm bore: push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181.0 N and pull 2040.3 N at 0.7 MPa; theoretical maximum 317.7 kgf at 1.0 MPa. Working pressure runs 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
Yes - open both cushion needle screws fully on first run, then close them gradually until the end-of-stroke thud disappears. The MAC's variable air cushion is adjustable rather than fixed, so retune it whenever speed or load changes within the 30-800 mm/s band.
