About the Airtac SAI50 Standard Cylinder SAI50BX700S
The AirTAC SAI50X700-S 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. With a 50 mm bore and 700 mm stroke, this tie-rod-less extruded aluminum barrel design provides a standardized mounting interface that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in washdown or humid settings. It also features a -S magnet option, allowing seamless integration with CMSE and DMSE sensor switches via the dual-side barrel grooves. The unit is equipped with PT tapered port threads and adjustable air cushions at both ends to manage piston deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50BX700S Is Used
Extended Stroke Material Transfer
Ideal for pushing heavy pallets or workpieces across a 700 mm gap on automated conveyor lines where 982 N of push force is required.
Vertical Lift Gates
Utilized in automated storage and retrieval systems to actuate long-travel lifting mechanisms, benefiting from the SUS304 rod's rust prevention.
Long-Reach Diverters
Serves as a diverter arm in packaging machinery, using the integrated magnet and CMSE sensors to confirm full extension at 700 mm.
Is the Airtac SAI50 Standard Cylinder SAI50BX700S the Right Cylinder?
Selecting this 50 mm bore over a smaller 40 mm variant upgrades your thrust from 628 N to 982 N at 0.5 MPa, providing a substantial capacity increase for heavier payloads. If your application requires even less force, stepping down to a 32 mm bore yields 402 N. The 700 mm stroke provides extensive reach, but long unsupported rods are highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external linear guide or utilize a guided cylinder assembly.
For applications that demand position holding or fail-safe load securement when air pressure is exhausted, the standard SAI profile will not suffice because the piston will drift. In these scenarios, specify the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock, to maintain load integrity. This model guarantees a true ISO 15552 direct replacement match for existing setups specifying a 50 mm bore, 700 mm stroke, G1/4 PT ports, and a magnet.
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 SAI50BX700S 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. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
