Airtac SAU Standard Air Cylinder SAU63X50
The AirTAC SAU Standard Air Cylinder SAU63X50 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAU Standard Air Cylinder SAU63X50
The AirTAC SAU63X50 is a double-acting profile-type cylinder engineered to be physically shorter than an ISO 15552 unit of the same bore, saving valuable machine space. It features a 3/8 inch port, an M16x1.5 rod thread, and delivers a robust 1559 N of push force at 0.5 MPa.
Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU63X50 Is Used
Clamp Actuation
Provides reliable 1559 N clamping force for securing heavy steel plates during CNC machining operations.
Package Diversion
Drives a robust 50 mm stroke diverter arm to route heavy industrial cartons along a main conveyor line.
Pallet Stopping
Acts as a heavy-duty pneumatic stop gate to halt loaded pallets at a specific packaging workstation.
Is the Airtac SAU Standard Air Cylinder SAU63X50 the Right Cylinder?
When sizing this actuator, compare it against its neighbours: the 50 mm bore yields 982 N of push at 0.5 MPa, while the larger 80 mm bore provides 2513 N. Choose the 63 mm bore when your application requires more power than the 50 mm but you want to avoid the bulk of the 80 mm. Mounting is straightforward using AirTAC SC-series accessories, including LB foot, FA/FB flange, or CA/CB clevis brackets.
Remember that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The adjustable air cushion at both ends only decelerates the piston near the stroke end and acts purely as an end-of-stroke damper, never as a locking brake. To suspend a load securely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAU Standard Air Cylinder SAU63X50 FAQ
The SAU63X50 features a 3/8 inch port and generates 1559 N push and 1402 N pull at 0.5 MPa. At 0.7 MPa it pushes 2182 N, and the theoretical maximum force is 318 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot support CMSG, DMSG, or EMSG magnetic switches. You must select an SAU63X50-S variant if position sensing is required.
