About the Airtac SAI63 Standard Cylinder SAI63BX700S
The AirTAC SAI63X700-S is a double-acting ISO 15552 profile cylinder engineered for a 63mm bore and 700mm stroke. It generates 1559 N of push force at 0.5 MPa, making it well-suited for high-cycle automation requiring substantial linear motion over an extended distance. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that matches standardized ISO 15552 mounting dimensions.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It is equipped with a magnetic piston (-S) to integrate seamlessly with CMSE and DMSE series reed switches, fitting directly into the dual sensor grooves machined into both sides of the barrel. Ports feature PT tapered threads for secure, pressure-tight pneumatic connections.

Where the Airtac SAI63 Standard Cylinder SAI63BX700S Is Used
Extended Material Handling
Drives long-travel pushers on sorting lines, utilizing the 700mm stroke to transfer heavy pallets or products between adjacent conveyor belts.
Automated Assembly Line
Provides the 1559 N thrust required to press bearings or pins over a wide operational envelope, with the SUS304 rod enduring factory humidity.
Vertical Lift Gates
Actuates heavy access doors or lifting platforms, relying on external linear guides to manage the side-load dynamics of the 700mm stroke.
Is the Airtac SAI63 Standard Cylinder SAI63BX700S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your push force from 982 N to 1559 N at 0.5 MPa, while stepping down from the 80mm bore (2513 N) saves footprint and air consumption without sacrificing moderate thrust. At a 700mm stroke, the unsupported rod length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and cylinder failure, strictly guide the load externally or utilize a guided cylinder module.
Because this is a double-acting pneumatic actuator, it cannot maintain a locked position if air pressure drops or the valve centers; the piston will drift. For vertical loads requiring fail-safe holding, utilize the SAIL (air-released lock) variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it acts as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, matching the 63mm bore, 700mm stroke, G3/8 port, and standard mounting accessories like TC trunnions or LB foot brackets.
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 SAI63 Standard Cylinder SAI63BX700S FAQ
At a 0.5 MPa operating pressure, this 63mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
It is dimensionally interchangeable with any true ISO 15552 profile cylinder. However, it is double-acting and will drift if air pressure is lost; for position holding, use the SAIL lock variant or an external rod lock.
