About the Airtac SAI100 Standard Air Cylinder SAI100BX250S
The AirTAC SAI100X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for high-thrust actuation over a 250 mm stroke. The extruded aluminum barrel eliminates external tie rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. Equipped with a built-in magnet (-S), the cylinder seamlessly integrates with CMSE and DMSE sensor switches fitted into the dual side grooves. Fluid ports feature PT tapered threads, and the standard TPU seals accommodate operating pressures from 0.15 to 1.0 MPa.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX250S Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N push force at 0.5 MPa to form and stamp thick metal components in automated fabrication lines.
Plastic Injection Molding
Utilizes the SUS304 rod and 250 mm stroke to extract large molded parts from machinery, resisting high-temperature and humid workshop conditions.
Pallet Handling
Drives heavy payload diverters and lifting mechanisms on conveyor systems, relying on ISO 15552 dimensions for straightforward machine integration.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX250S the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application demands substantial thrust that smaller bores cannot provide, such as stepping up from a 80 mm bore which yields 2513 N at 0.5 MPa. If precise positioning or holding a load without continuous air pressure is required, note that the standard adjustable air cushions only decelerate the piston at stroke ends. For dead-end holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
With a 250 mm stroke, the unsupported rod length is moderate, but operators should still verify side-load conditions. For applications involving heavy lateral forces, pair this cylinder with external guides or utilize a guided cylinder carriage to prevent premature rod-bearing wear. Replacement interchangeability requires matching the 100 mm bore, 250 mm stroke, G1/2 port, and appropriate mounting accessories like FA flange or TC trunnion.
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 SAI100BX250S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X250-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing setups matching the 100 mm bore, 250 mm stroke, and G1/2 port configuration without modifying the mounting interface.
