This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100BX60, 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 SI100BX60
The AirTAC Airtac SI100 Standard Cylinder SI100BX60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100BX60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100BX60
The AirTAC SI100BX60 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 60mm stroke. It delivers a push force of 3927 N at 0.5 MPa via a G1/2 port. This SKU uses a SUS304 stainless piston rod (the -B option) for corrosion resistance, but lacks a magnet, so it cannot accept a position switch.
You must order the direct replacement SAI100BX60. It shares the exact ISO 15552 mounting interface, bore, stroke, force, port and accessories. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100BX60 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100BX60 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100BX60 Is Used
Heavy-Duty Pressing
Drives high-force stamping and forming operations, utilising the 3927 N push capacity at 0.5 MPa to seat bearings and assemble heavy components.
Pallet Dispenser
Actuates robust pallet handling mechanisms in automated warehouses, where the SUS304 stainless rod resists moisture and environmental wear.
Logistics Diverter
Pushes heavy parcels across sorting lines, handling the dynamic loads of high-speed distribution with a 60mm stroke and adjustable end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100BX60 with the SAI100BX60
To replace this SI100BX60 with the SAI100BX60, verify the ISO 15552 mounting interface, the 60mm stroke, and the G1/2 port (PT/G/NPT thread options). Because this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if you need switches. Sizing both ways: the 100mm bore yields 3927 N push at 0.5 MPa, while the neighbouring 80mm bore provides 2513 N. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates. Use an external pilot check valve, or explore the SAIL or BSAI lock variants for secure holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100BX60
- ✓ 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 SI100BX60 FAQ
Yes, the SI100BX60 is discontinued. The direct replacement is the AirTAC SAI100BX60. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 60mm stroke, 3927 N force, G1/2 port, and mounting accessories.
This double-acting cylinder has a G1/2 port. The thrust figures are: 3927 N push and 3681 N pull at 0.5 MPa; 5497 N push at 0.7 MPa; 7068 N push at 0.9 MPa; and a theoretical maximum force of 801 kgf at 1.0 MPa.
