About the Airtac SAI50 Standard Cylinder SAI50BX700
The AirTAC SAI50X700 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 700mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring extended travel. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies the mounting of switches and accessories.
This specific configuration includes a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for humid or wash-down environments. It utilizes PT tapered port threads and does not include a magnet for proximity sensors. For applications needing end-position sensing, the -S variant would be required to house CMSE or DMSE switches in the dual-side barrel grooves.

Where the Airtac SAI50 Standard Cylinder SAI50BX700 Is Used
Extended Material Handling
Drives long-travel pushers on conveyor lines, utilizing the 700mm stroke to transfer packages between sorting zones efficiently.
Automated Assembly Elevators
Raises and lowers tooling platforms in automated machinery where the 982N force capacity easily handles the payload weight.
Corrosion-Resistant Actuation
Ideal for packaging lines in humid environments, leveraging the SUS304 stainless steel rod to prevent rust and ensure long service life.
Is the Airtac SAI50 Standard Cylinder SAI50BX700 the Right Cylinder?
Selecting this 50mm bore cylinder is appropriate when your application requires around 982N of force at 0.5 MPa, stepping up from the 40mm bore (628N) or down from the 63mm bore (1559N). The 700mm stroke is a standard length, but at this extended travel, the unsupported rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod bearing failure, use an external guide rail or a fully guided cylinder to absorb lateral forces.
As a standard double-acting cylinder, the SAI50X700 relies on live air pressure to move and hold the load; it will drift if air is exhausted or the valve is centered. The adjustable air cushions at both ends decelerate the piston near the stroke limits but do not function as a mechanical lock. If your process requires true position holding without continuous air pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model provides a direct replacement for any ISO 15552 mounting interface utilizing a 50mm bore, 700mm stroke, and G1/4 ports.
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 SAI50BX700 FAQ
At 0.5 MPa, the SAI50X700 provides 982N of push force and 825N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver a theoretical maximum force of 200 kgf.
Yes, the SAI50X700 is built to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same 50mm bore and 700mm stroke. It is not a tie-rod cylinder, ensuring a clean exterior profile.
