Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 550mm 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 MAC63X550SCM
For long-reach lifting, the MAC63X550SCM pairs the largest MAC bore with a 550 mm stroke and a CM round-end back cover whose rounded boss suits clevis brackets and eye mounts. Pushing with 1557.9 N at 0.5 MPa - 2181.0 N at 0.7 MPa - the double-acting piston retracts with 1457.4 N, and both ends carry a variable air cushion you set with the needle screws. Theoretical force at 1.0 MPa touches 317.7 kgf.
The round stainless body with rolled-riveted aluminium covers and a 20 um hard-chrome rod stands up to washdown lines and outdoor yards where painted minis corrode fast. Watch two limits: 550 mm is a non-standard stroke produced to order, and on a vertical lift the piston falls freely if air is lost, so a rod lock or pilot check valve is required to hold the load. Working from the 0.5 MPa rating, expect about 935 N of usable force, which vertically equates to lifting near 79 kg at half capacity. The standard-built magnet pairs with CMSG, DMSG and EMSG switches for position feedback.

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 MAC63X550SCM Is Used
Die-change clamp lift
Raises die-clamp levers on a press die-change trolley; the 550 mm stroke clears the full bolster height and 1557.9 N at 0.5 MPa lifts the latched clamp arms.
Vertical tote elevator
Hoists a tote platform between two conveyor levels; at half capacity the bore manages close to 79 kg including the platform, with the cushion settling each landing.
Mixer hood raise
Lifts the hinged lid of a 200-litre drum mixer before charging; cushioning at both travel ends keeps the heavy hood from slamming open or shut.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X550SCM the Right Cylinder?
Against the 63 mm figures, a 32 mm bore would offer only 402.2 N push at 0.5 MPa - roughly a quarter - so heavy long-stroke lifts genuinely need this bore. Because the load hangs on the rod whenever the valve centres, plan a rod lock or pilot check valve into the circuit from day one. Choose the CM round end with an SDB pivot bracket for swinging duty, or an LB foot / FA flange for fixed frames. At the upper end of the 30-800 mm/s speed range, decelerate the load with the built-in cushion rather than hard stops, and guide long 550 mm strokes to protect the 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 MAC63X550SCM FAQ
Push at 0.5 MPa is 1557.9 N and pull is 1457.4 N; at 0.7 MPa push is 2181.0 N and pull 2040.3 N; the theoretical maximum is 317.7 kgf at 1.0 MPa. Run it on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, proof pressure 1.5 MPa (215 psi), rod speed 30-800 mm/s, with 1/4 in ports and an M14x1.5 male rod thread.
The CM cover ends in a rounded boss that accepts clevis and eye brackets for pivoting or lifting motion. The covers are rolled and riveted onto the stainless-steel tube rather than clamped, giving a compact round body that seals reliably in washdown and outdoor environments, with the hard-chrome plated rod keeping wear low.
