This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX95, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100BX95
The AirTAC Airtac SI100 Standard Cylinder SI100BX95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 95mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX95, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX95
The AirTAC SI100BX95 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore, 95mm stroke, and a SUS304 stainless steel rod. Delivering 3927 N push force at 0.5 MPa, it is replaced by the SAI100BX95 direct. This upgrade shares the exact ISO 15552 mounting interface, G1/2 port, and 801 kgf max force. The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure, and adds SAIL, SAIF, and BSAI variants the SI lacked.
As a non-magnetic SKU, this cylinder cannot take a sensor. Note that 95mm is a non-standard stroke. The cushion only decelerates; use SAIL or BSAI for load holding.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100BX95 Is Used
Stainless Rod Clamping
Ideal for machining fixtures requiring corrosion resistance, using the SUS304 rod to clamp heavy castings with 3927 N of force at 0.5 MPa.
Heavy Product Diversion
Provides robust 100mm bore push force for diverting large pallets or heavy goods on packaging lines, operating at speeds up to 800 mm/s.
Pallet Lift Stops
Acts as a high-force mechanical stop in automated storage systems, handling dynamic impacts with its 36mm adjustable air cushions at both ends.
Replacing the Airtac SI100 Standard Cylinder SI100BX95 with the SAI100BX95
To replace this discontinued SI100BX95, order the SAI100BX95. Confirm the ISO 15552 mounting interface, the 100mm bore, the 95mm non-standard stroke, the G1/2 port, and your mounting accessory. Because this SKU lacks a magnet (-S), it cannot accept a CS1-B or DS1-B sensor; if sensing is needed, switch to an SAI100X*S equivalent. The stainless SUS304 rod is retained. If sizing up or down, neighboring bores are 80mm (2513 N [email protected]) and 125mm (6136 N [email protected]). For load holding without live air, a plain cylinder drifts; use an external pilot check valve or the SAIL/BSAI lock variants. With a 95mm stroke, side-load risks are low, but always verify rod-bending limits if guiding heavy loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX95
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100BX95 FAQ
Yes, the AirTAC SI100BX95 is discontinued. The direct replacement is the SAI100BX95. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 95mm stroke, G1/2 port, and mounting interface.
This double-acting cylinder has a G1/2 port. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
