Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MAC63X75SCM
With a 63 mm barrel pushing 1557.9 N at 0.5 MPa (and 2181.0 N at 0.7 MPa), the MAC63X75SCM is the heavy hitter of AirTAC's MAC round-body range. Air drives the rod out and back, so it is double acting throughout, and a variable air cushion at each end lets you bleed off end-of-stroke shock before it reaches the covers.
The riveted stainless barrel and hard-chrome plated rod shrug off washdown and mild corrosion, a real edge over painted minis in damp plants. The CM round-end back cover gives a clean pivoting attachment without extra brackets, and the built-in magnet (standard) accepts CMSG, DMSG or EMSG switches. Running the 75 mm stroke anywhere from 30 to 800 mm/s, plan work around 935 N - roughly six tenths of the 0.5 MPa push rating - for long seal life.

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 MAC63X75SCM Is Used
Press transfer arm
A 75 mm stroke indexes cast housings weighing up to 79 kg into a deburring fixture on a foundry line; the cushion absorbs the stop.
Case kickers
Kicks heavy cartons off a palletising conveyor at 0.5 MPa, with the round-end cover taking the pivot load without adapters.
Weld frame clamp
Pulls at 1457.4 N to hold steel tube frames against weld stops; magnet switches confirm jaw open and closed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X75SCM the Right Cylinder?
Need less muscle? A 50 mm bore still gives 981.3 N at 0.5 MPa and costs less air; nothing in the MAC range out-pushes 63 mm, so this is the top step. The CM round-end cover pairs directly with a clevis pin; add SDB or LB if the frame needs a foot. Note the piston drifts when the valve is centred or air drops - fit a rod lock or pilot check valve if the load must stay put. 1/4" ports, M14x1.5 rod thread, 16 mm rod.
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 MAC63X75SCM FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N. At 0.7 MPa the figures rise to 2181.0 N push and 2040.3 N pull. The theoretical maximum at 1.0 MPa is 317.7 kgf. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The CM back cover presents a rounded pivot face for clevis or bracket attachment without adapters. The variable air cushion at both ends is set with needle screws - back them off before first run, then close gradually until the 30-800 mm/s stroke stops cleanly.
