About the Airtac SAI63 Standard Cylinder SAI63BX350S
The AirTAC SAI63X350-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa. Its 350 mm stroke provides the extended travel needed for mid-sized material handling and automated positioning tasks. As a genuine AirTAC component, it ensures dimensional interchangeability with standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. The integrated magnet (-S) allows seamless operation with CMSE and DMSE sensor switches, which mount directly into the dual extruded barrel grooves. Adjustable air cushions at both ends protect the end caps from impact damage during high-speed cycles.

Where the Airtac SAI63 Standard Cylinder SAI63BX350S Is Used
Package Diversion
Extends 350 mm to push heavy cartons off a main conveyor line, utilizing the 1559 N thrust at 0.5 MPa to overcome box inertia without compressed air spikes.
Component Seating
Presses bearings or bushings into housings on an automated assembly line, relying on the SUS304 rod for durability in lightly corrosive production areas.
Pallet Handling
Actuates a mid-stroke lifting gate or stopper mechanism in a pallet routing cell, where the dual sensor grooves allow flexible switch placement for precise positioning.
Is the Airtac SAI63 Standard Cylinder SAI63BX350S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore cylinder (offering 982 N push at 0.5 MPa) cannot provide enough thrust, but an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized and consume excess air. The 350 mm stroke requires careful mounting to prevent rod-bearing bending; for applications with heavy side loads, pair this cylinder with an external guide rail or select a guided cylinder to prevent premature seal wear.
Because the SAI is a double-acting pneumatic actuator, it relies on continuous air pressure to maintain its position. If your application requires the load to stay fixed during a pressure loss or valve centering, use the SAIL variant with an air-released lock or an external pilot-operated check valve. This model features PT tapered port threads and utilizes standard ISO 15552 mounting accessories like FA flanges or TC trunnions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI63 Standard Cylinder SAI63BX350S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 2182 N.
Yes. The SAI63X350-S is built to the ISO 15552 profile standard, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. You can reuse existing mounting accessories like LB foot brackets or TC trunnions.
