About the Airtac SAI50 Standard Cylinder SAI50BX800S
The AirTAC SAI50X800-S is a double-acting ISO 15552 profile cylinder engineered for long-trroke linear actuation. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for moving moderate loads over an 800 mm span.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual barrel grooves. It utilizes PT tapered ports and supports high-temperature Viton (H) seals if your thermal environment demands it.

Where the Airtac SAI50 Standard Cylinder SAI50BX800S Is Used
Long-Stroke Material Transfer
Pushes products or pallets across an 800 mm gap on a packaging line, utilizing the 982 N push force to overcome friction.
High-Reach Diverting
Actuates a diverting arm at elevation, where the SUS304 rod provides necessary resilience against ambient moisture.
Automated Door Operation
Opens and closes large machine safety doors, relying on adjustable air cushions to soften the impact at full extension.
Is the Airtac SAI50 Standard Cylinder SAI50BX800S the Right Cylinder?
Selecting this 50 mm bore over a smaller 40 mm option steps the thrust up from 628 N to 982 N at 0.5 MPa, providing extra margin for heavier 800 mm strokes. If your application requires even less force, stepping down to a 32 mm bore yields 402 N but may struggle with long-stroke inertia.
Because this model features an 800 mm stroke, the unsupported rod is highly susceptible to bending under side loads. Utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear. Furthermore, standard air cushions only decelerate the piston at end-of-stroke; they will not hold a load vertically if air pressure drops. For secure position holding, consider the SAIL lock variant.
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 SAI50 Standard Cylinder SAI50BX800S FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X800-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders with a 50 mm bore and 800 mm stroke, matching the PT port and mounting accessories.
