About the Airtac SAI63 Standard Cylinder SAI63BX150S
The AirTAC SAI63X150-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit is built for robust actuation. The 150 mm stroke provides the travel distance needed for mid-range material handling and clamping tasks.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), it supports CMSE and DMSE sensor switches that mount directly into the extruded aluminum barrel grooves. It operates at speeds from 30-800 mm/s and uses a G3/8 port.

Where the Airtac SAI63 Standard Cylinder SAI63BX150S Is Used
Mid-Tonnage Stamping
Provides reliable clamping force for holding sheet metal or composite parts during light stamping and machining operations.
Package Diversion
Drives robust pusher arms on packaging lines to redirect heavier cartons or totes at high cycling speeds.
Material Lifts
Actuates small lifting platforms or shuttle mechanisms where a 150 mm stroke moves workpieces between processing stations.
Is the Airtac SAI63 Standard Cylinder SAI63BX150S the Right Cylinder?
Select this 63 mm bore when an application requires more power than a 50 mm cylinder (which provides 982 N push at 0.5 MPa) but without the larger footprint of an 80 mm unit (2513 N). The 150 mm stroke offers a compact extension length that minimizes rod-bearing stress, though any side load should still be managed with external guides to prevent premature seal wear.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. To match this exact configuration, specify the 63 mm bore, 150 mm stroke, PT tapered G3/8 port, and the -S magnet option. Note that standard SAI cylinders do not hold position upon air loss; use the SAIL variant if pneumatic locking is required.
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 SAI63BX150S FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI series is built to ISO 15552 dimensional standards, making it a direct replacement for other profile cylinders with matching mounting interfaces. Ensure your setup matches the 63 mm bore, 150 mm stroke, and G3/8 port.
