About the Airtac SAI100 Standard Air Cylinder SAI100BX260S
The AirTAC SAI100X260-S is a double-acting profile cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 cylinders. It delivers a robust 3927 N push force and 3681 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks over its 260 mm stroke.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance and features a built-in magnet (-S) that enables direct mounting of CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX260S Is Used
Heavy Machinery Clamping
Ideal for securing large metal castings during machining, using its 3927 N push force to hold workpieces firmly against fixture stops.
Pallet Diverting
Provides reliable lateral pushing power on automated conveyor lines to sort or redirect heavy palletized goods over a 260 mm distance.
Press Operations
Excellent for light-duty pressing and assembly tasks where consistent force and adjustable end-of-stroke air cushions protect the tooling.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX260S the Right Cylinder?
Providing 3927 N at 0.5 MPa, this 100 mm bore offers substantial thrust for heavy loads; if your application requires less force, stepping down to an 80 mm bore yields 2513 N. Because this model features a 260 mm stroke, maintaining proper alignment is critical to prevent rod-bearing bending under side loads. Utilizing external guides or a fully guided cylinder will ensure smooth operation and extend seal life.
This standard SAI variant relies entirely on live air pressure to hold its position; if air is lost, the piston drifts. For applications requiring true position holding without constant pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. Replacement and interchangeability specs: 100 mm bore, 260 mm stroke, G1/2 port (PT tapered thread), compatible with FA/FB flange or TC trunnion mounts, and includes a magnet for sensors.
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 SAI100BX260S 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 SAI series is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders. It uses a G1/2 port and supports standard FA, FB, and TC mounting accessories.
