About the Airtac SAI63 Standard Cylinder SAI63BX195
The AirTAC SAI63X195 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Featuring a 63 mm bore and a 195 mm stroke, it provides robust linear motion for mid-range industrial tasks. This specific configuration is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads.
Because it adheres strictly to ISO 15552 dimensional standards, this tie-rod-less profile cylinder serves as a direct replacement for other ISO 15552 units. The extruded aluminum barrel includes sensor grooves on both sides, allowing for easy integration of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI63 Standard Cylinder SAI63BX195 Is Used
Mid-Range Material Lifts
Ideal for elevating workpieces on automated lines, utilizing its 1559 N push force at 0.5 MPa to raise and lower heavy jigs reliably.
Package Diverting
Provides the stroke length and thrust needed to actuate diverter arms on packaging conveyors, pushing cartons smoothly to adjacent lanes.
Clamping Fixtures
Well-suited for holding components securely in machining or welding fixtures where consistent clamping force is required.
Is the Airtac SAI63 Standard Cylinder SAI63BX195 the Right Cylinder?
Select this 63 mm bore when an application requires stepping up from a 50 mm cylinder (which provides 982 N push at 0.5 MPa) to handle heavier payloads without jumping to the larger 80 mm footprint. The 195 mm stroke offers ample extension for indexing and lifting tasks. To match an existing setup, specify the 63 mm bore, 195 mm stroke, PT port thread, and the desired mounting accessory such as an LB foot or TC trunnion.
For loads that must remain suspended or held in place during a loss of air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke end and does not function as a brake. In safety-critical holding scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
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 SAI63BX195 FAQ
