About the Airtac SAI100 Standard Air Cylinder SAI100BX290S
The AirTAC SAI100X290-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 3927 N of push force at 0.5 MPa. With a 100 mm bore and 290 mm stroke, this unit is built for substantial actuation tasks requiring significant linear movement.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) that enables direct mounting of CMSE or DMSE series reed switches. The extruded aluminum barrel features integrated sensor grooves on both sides, and the pneumatic ports utilize a PT tapered thread standard.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX290S Is Used
Heavy-Duty Pressing
Provides the 3927 N push force required for seating bearings, stamping light-gauge metal, and assembling heavy mechanical components.
Pallet Diverting
Handles large product loads on conveyor lines, using the 290 mm stroke to push heavy pallets onto secondary processing tracks.
Automated Clamping
Secures bulky workpieces or machinery frames during machining or welding operations where high holding strength is necessary.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX290S the Right Cylinder?
Selecting this 100 mm bore over a smaller 80 mm variant provides a significant thrust upgrade, stepping up from 2513 N to 3927 N at 0.5 MPa. If your application requires less force, dropping to the 80 mm bore can save space and air consumption.
Because this model features a 290 mm stroke, the extended rod is susceptible to bending under side loads. To prevent premature wear on the rod bearing and seals, implement an external guide rail or use a guided cylinder mechanism. Note that the standard adjustable air cushions at both ends only decelerate the piston; they do not hold a load. If pressure is lost, the piston will drift. For position holding without live air pressure, consider the SAIL locking variant or an external rod lock.
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 SAI100BX290S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. It can reach up to 5497 N at 0.7 MPa.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 standards. It serves as a drop-in replacement for other ISO 15552 profile cylinders of the same bore and stroke, matching standard mounting and PT port dimensions.
