About the Airtac SAI100 Standard Air Cylinder SAI100BX35S
The AirTAC SAI100X35-S is a double-acting ISO 15552 profile cylinder engineered for high-force automation. Delivering a robust 3927 N of push force at just 0.5 MPa, it is designed to handle heavy loads within a compact 35 mm stroke. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that conforms to strict ISO 15552 mounting dimensions.
This specific configuration features a SUS304 stainless steel piston rod (material code B), ensuring superior corrosion resistance in harsh environments. Equipped with a magnet (-S), the cylinder integrates seamlessly with CMSE and DMSE reed switches fitted into the dual-side sensor grooves. Fluid connections use PT tapered threads, matching the G1/2 port standard for this 100 mm bore size.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX35S Is Used
Heavy-Duty Stamping
Generates 3927 N of thrust at 0.5 MPa for short-stroke metal forming and embossing tasks.
Pallet Clamping
Holds heavy pallets securely in place during machining or packaging operations using the 35 mm stroke.
Press Fit Assembly
Delivers the necessary blunt force to seat bearings and bushings into housings without over-traveling.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX35S the Right Cylinder?
Select this 100 mm bore when an application demands more power than the 80 mm variant, which provides 2513 N at 0.5 MPa. The 35 mm short stroke is optimal for high-force clamping or pressing tasks where travel distance is minimal. Because the stroke is under 300 mm, side-load bending stress on the rod bearing is naturally limited.
If the machinery requires the load to remain suspended or held without continuous air pressure, a standard SAI cylinder will drift and drop. In these cases, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. This model serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders, utilizing standard FA/FB flange or TC trunnion mounts.
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 SAI100 Standard Air Cylinder SAI100BX35S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If your system runs at 0.7 MPa, the push force increases to 5497 N.
No, the standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston, but it cannot hold a load without live pressure. For vertical holding, use the SAIL variant with an air-released lock.
