Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 150mm 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 MAC63X150SCA
With 1558 N of push at 0.5 MPa (73 psi) behind a 150 mm stroke, MAC63X150SCA covers the heaviest tasks a mini round-body cylinder can reach: clamping, lifting and pushing from a compact stainless barrel. Air drives the piston both ways, and needle-adjustable cushions at each end let you tune deceleration to the load.
The body is assembled by rolling the aluminium-alloy covers and a stainless block onto the stainless tube, a packing method that keeps the seal tight for life, while the two-way piston seal doubles as a grease reservoir for long service. The magnet fitted as standard pairs with CMSG, DMSG and EMSG switches for end-of-stroke signalling. Budget about 935 N of usable force at 0.5 MPa - in lift terms, roughly 79 kg carried vertically with a comfortable 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 MAC63X150SCA Is Used
Case-ejector on a carton packer
Kicking formed cartons off a downstream infeed where 1558 N shoves a full row clear; the cushion stops the ram cracking the side frames.
Index table lock pin on a rotary dial machine
Driving a locking pin in and out of a dial-plate hole through a short linkage hung off the CA pivot eye.
Pallet-stacker mast latch
Releasing a mast latch on a warehouse lift where the 150 mm stroke clears the hook fully and the magnet feeds position to the safety circuit.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X150SCA the Right Cylinder?
Downsizing to a 40 mm bore drops you to 628 N at 0.5 MPa - a big step - so check the load before choosing; upsizing is not possible because 63 mm tops the range, and extra force must come from higher pressure (2181 N at 0.7 MPa). Remember the piston coasts freely if supply air fails; a pilot check valve or rod lock holds it. The CA eye on the back cover pivots freely for linkage duty, while FA flange, LB foot and SDB mounts cover fixed installations, and I or Y knuckles adapt the 16 mm rod. Over a 150 mm stroke, support side loads with external guides to keep rod wear down.
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 MAC63X150SCA FAQ
Push 1558 N and pull 1457 N at 0.5 MPa; push 2181 N and pull 2040 N at 0.7 MPa; theoretical peak 317.7 kgf at 1.0 MPa. The rod is 16 mm in diameter with an M14x1.5 thread, air ports are 1/4", and strokes beyond 500 mm for this bore become made-to-order.
The tube is stainless steel and the rod is carbon steel with a 20 um hard-chrome layer, so mild corrosion, washdown and outdoor exposure are far less damaging than on painted-steel minis. The aluminium-alloy covers are rolled onto the tube for a sealed round body, and the piston seal stores its own grease, stretching maintenance intervals.
