This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32BX170, 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 SI32 Standard Air Cylinder SI32BX170
The AirTAC SI32 Standard Air Cylinder SI32BX170 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32BX170, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX170
The AirTAC SI32BX170 is a discontinued double-acting ISO 15552 profile cylinder with a 32 mm bore and 170 mm stroke. It delivers 402 N push force at 0.5 MPa through a G1/8 port. The direct replacement is the SAI32BX170, matching the interface, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU uses a SUS304 stainless rod (-B) and has no magnet, so it cannot take a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX170 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32BX170 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX170 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight machined components out of a fixture.
Corrosive Environment Sorting
The SUS304 stainless piston rod operates smoothly in damp washdown areas where standard carbon steel rods would degrade.
Material Diverting
Cycles at 30-800 mm/s to actuate small diverter gates on a packaging line without requiring magnetic feedback.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX170 with the SAI32BX170
To replace this SI32BX170 with the SAI32BX170, verify the ISO 15552 mounting interface, 170 mm stroke, and G1/8 port. This unit lacks a magnet (-S), meaning no CS1-B/DS1-B sensor can be fitted; order an -S version if position detection is needed. The SUS304 stainless rod suits corrosive settings. For higher force, the 40 mm bore yields 628 N push at 0.5 MPa. Note that plain cylinders drift without air; for load holding, use an external pilot check valve or the SAIL lock variant. At 170 mm stroke, rod bending is low, but ensure guide alignment to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX170
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32BX170 FAQ
Yes, the SI32BX170 is discontinued. The direct replacement is the SAI32BX170. It is dimensionally interchangeable per ISO 15552, matching the 32 mm bore, 170 mm stroke, G1/8 port, and mounting accessories.
It features a G1/8 port and provides 402 N push / 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The air cushion decelerates the load but does not hold it without live air.
