About the Airtac SAI63 Standard Cylinder SAI63BX210
The AirTAC SAI63X210 is a double-acting ISO 15552 profile cylinder engineered for rigorous industrial automation. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit paired with a 210 mm stroke excels in mid-range actuation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in wet or chemically exposed environments. It utilizes PT tapered port threads and lacks a piston magnet. For operations requiring end-position holding under pressure loss, consider the SAIL locking variant.

Where the Airtac SAI63 Standard Cylinder SAI63BX210 Is Used
Material Forming
Provides the 1559 N force needed at 0.5 MPa for medium-duty bending, clamping, and stamping operations.
Package Diverting
Actuates sorting arms and diverter gates on high-speed packaging lines with a reliable 210 mm travel.
Corrosive Environments
The SUS304 stainless steel rod withstands washdowns and chemical exposure in food or pharmaceutical processing.
Is the Airtac SAI63 Standard Cylinder SAI63BX210 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm option upgrades your 0.5 MPa push force from 982 N to 1559 N, while stepping up to the 80 mm bore yields 2513 N. The 210 mm stroke falls below the 300 mm threshold, minimizing severe rod-bearing bending, but you should still avoid excessive side loads.
As a standard ISO 15552 profile cylinder, it serves as a direct replacement for any cylinder matching this bore, 210 mm stroke, G3/8 port, and PT thread interface. Mounting accessories include FA flanges or TC trunnions. Because this unit lacks a piston magnet, position sensing via CMSE or DMSE switches is not possible without modifying the configuration. Remember that standard air cushions only decelerate the piston near stroke ends; they do not hold loads when air pressure is removed.
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.
