Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MAC63X50SCA
Short stroke, full muscle: with only 50 mm of travel, this 63 mm bore MAC still delivers 1557.9 N of push and 1457.4 N of pull at 0.5 MPa, and 2181.0 N / 2040.3 N at 0.7 MPa. As a double acting cylinder with a variable air cushion at each end, it soaks up the shock of a fast clamp instead of passing it into the frame. For dependable sizing, plan the actual clamping effort near 935 N at 0.5 MPa and let the rest stay as margin.
The CA pivot back cover means the cylinder can swing with a lever or toggle link, no fabricated bracket required. Inside, the riveted stainless-steel barrel and hard-chrome plated rod resist coolants and washdown that ruin painted minis, and the magnet fitted as standard lets CMSG / DMSG / EMSG switches confirm clamp-on and clamp-off. Air supply is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, through 1/4" ports.

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 MAC63X50SCA Is Used
Welding fixture toggle clamp
Driving a toggle linkage that clamps steel tube before welding; about 935 N of practical force at 0.5 MPa holds parts against weld shrinkage while the CA pivot follows the linkage arc.
Drum-lid hold-down
Clamping lids on a 200 litre drum filling station; pull force of 1457.4 N at 0.5 MPa keeps the lid seated while foam purges, verified by a clip-on CMSG switch.
Hopper gate latch
Locking a powder hopper slide gate shut; 2181.0 N at 0.7 MPa seats the gate against product pressure and the end cushion prevents a metal-to-metal slam.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X50SCA the Right Cylinder?
Against the 50 mm bore, which manages 981.3 N push at 0.5 MPa, this cylinder adds roughly 59% more force over the same 50 mm stroke - and 63 mm is already the largest MAC bore, so there is no step up if 1557.9 N feels marginal. Do not rely on the cylinder to hold a clamped position through air loss; the piston can drift, so a pilot check valve or rod lock is the fail-secure answer. The CA pivot pairs naturally with SDB pivot brackets, while FA flanges and LB feet suit fixed frames, and I / Y knuckles on the M14x1.5 rod thread handle linkage duty. CMSG / DMSG / EMSG switches read clamp state straight off the barrel thanks to the standard magnet.
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 MAC63X50SCA FAQ
Push is 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa the figures are 2181.0 N push and 2040.3 N pull; theoretical maximum output is 317.7 kgf at 1.0 MPa. It is double acting with 50 mm stroke, runs 30-800 mm/s, works on 0.15-1.0 MPa (22-145 psi), is proof tested at 1.5 MPa (215 psi), and breathes through 1/4" ports.
Yes, but start with both cushion needle screws fully open and close them in small steps until the clamp lands quietly - the cushion volume is small at 50 mm stroke. Remember it is an air damper, not a brake: if pressure drops the piston can move, so use a pilot check valve or rod lock wherever the clamp must stay secure.
