Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 450mm 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 MAC63X450SCM
With a 450 mm stroke on the largest bore of the MA family, the MAC63X450SCM is a double-acting round-body mini cylinder that moves serious weight at speed, cushioned by variable air damping at both ends. At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N, climbing to 2181.0 N at 0.7 MPa.
The CM round-end back cover is machined for eye or clevis-style pivoting without extra adapter plates, and the riveted stainless barrel with a 20 um hard-chrome plated rod stands up to washdown better than painted minis. In practice, plan loads around 935 N of continuous push at 0.5 MPa, which is enough to lift roughly 79 kg vertically on a 2:1 margin.

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 MAC63X450SCM Is Used
Lift-gate counterweight raise
Raising a 70 kg service-lift gate through 450 mm at 0.5 MPa uses about 687 N, comfortably inside the cylinder's 935 N working band, with cushions catching the top of travel.
Carton pusher on a wide pallet conveyor
A 1.4 m wide pallet line needs a long-throw pusher; 450 mm of stroke and 1557.9 N of push at 0.5 MPa shoves loaded pallets sideways while the cushion damps impact into the stop.
Counterbalance dampener on a mast test rig
Bench-testing forklift mast rollers through a 450 mm sweep, the round-end CM cover pins straight to the rig linkage and the variable cushion absorbs the rebound.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X450SCM the Right Cylinder?
Bore 63 is the top of the MAC range, so nothing in the family out-pushes it; if 981.3 N at 0.5 MPa from a bore 50 cylinder already covers the job, step down to save air. Remember this is a plain double-acting cylinder: when the valve centres or air drops, the rod coasts freely, so add a pilot check valve or rod lock if the 450 mm travel must park under load. The built-in magnet works with CMSG, DMSG and EMSG switches out of the box, and the CM back cover plus optional LB foot or FA flange mount covers most frames. Over 450 mm of travel even a small side load bends the 16 mm rod - guide the load externally on slides or guides.
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 MAC63X450SCM FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa those rise to 2181.0 N and 2040.3 N. The theoretical ceiling is 317.7 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um, at 30-800 mm/s, with a 1/4" port and M14x1.5 male rod thread.
The round-end cover takes a pivot pin directly, so linkage mounts need no extra bracket, and FA flange or LB foot hardware bolts on when a fixed base suits better. Every MAC ships with the magnet already in the piston, so CMSG, DMSG or EMSG switches click on at any point along the 450 mm barrel for position feedback.
