Airtac SAI50 Standard Cylinder SAI50BX650
The AirTAC SAI50 Standard Cylinder SAI50BX650 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 650mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAI50 Standard Cylinder SAI50BX650
The AirTAC SAI50X650 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and utilizes a PT tapered port thread. With a 650 mm stroke, it is tailored for extended travel distances in automated machinery.
Unlike basic models, this variant omits the internal magnet, meaning it is not compatible with CMSE or DMSE reed switches out of the box. If your workflow demands holding a load securely without sustained air pressure, consider integrating the SAIL locking variant or an external pilot-operated check valve, as the standard adjustable air cushions only decelerate the piston near stroke end.

Where the Airtac SAI50 Standard Cylinder SAI50BX650 Is Used
Material Handling
Drives long-travel diverters and package pushers on automated sorting lines requiring a 650 mm reach.
Assembly Automation
Actuates large-format component placement fixtures where a 982 N push force is sufficient for positioning.
Palletizing
Indexes lightweight pallet layers or acts as a horizontal transfer barrier in high-bay storage systems.
Is the Airtac SAI50 Standard Cylinder SAI50BX650 the Right Cylinder?
Generating 982 N at just 0.5 MPa, this 50 mm bore provides a balanced middle ground between the lighter 40 mm bore (628 N) and the heavier 63 mm bore (1559 N). For this 650 mm stroke, managing side load is critical because long unsupported rods are highly susceptible to bending. To prevent premature rod-bearing wear, mount an external guide rail or select a guided cylinder carriage.
As a true ISO 15552 profile extrusion, it serves as a direct replacement for any cylinder matching those mounting-interface dimensions. When ordering, confirm the PT port, the 50 mm bore, the 650 mm stroke, and your preferred mounting accessory like an FA flange or TC trunnion.
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.
