This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X75SLB, 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 SI32X75SLB
The AirTAC SI32 Standard Air Cylinder SI32X75SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X75SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X75SLB
The AirTAC SI32X75SLB is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 75mm stroke. Delivering 402N push force at 0.5MPa through a G1/8 port, it is directly replaced by the SAI32X75SLB. This direct upgrade retains the exact ISO 15552 mounting interface, LB foot bracket, and M10x1.25 rod thread for seamless fixture integration.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. This unit includes a piston magnet for CS1-B/DS1-B sensors, and Viton H seals can raise the operating temperature to 150C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X75SLB 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 | — |

Where the Airtac SI32 Standard Air Cylinder SI32X75SLB Is Used
Package Diverting
Provides reliable 75mm stroke actuation to sort or divert small cartons on a packaging line at speeds up to 800mm/s.
Clamp Actuation
Generates 402N of thrust to secure small workpieces during secondary machining or light assembly processes.
Replacing the Airtac SI32 Standard Air Cylinder SI32X75SLB with the SAI32X75SLB
To replace the SI32X75SLB, order the SAI32X75SLB. Verify the ISO 15552 LB foot mounting, 75mm stroke, G1/8 port, and the -S magnet for legacy CS1-B/DS1-B switches (the SAI uses current AirTAC switches). For sizing down, a 32mm bore at 0.5MPa gives 402N push and 345N pull; sizing up to 40mm increases push to 628N. Note that plain cylinders drift on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL lock and SAIF integrated 4M valve variants (bores 32-100) that the SI line lacked.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X75SLB
- ✓ 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 SI32X75SLB FAQ
Yes, the AirTAC SI32X75SLB is discontinued. The direct replacement is the SAI32X75SLB. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 75mm stroke, G1/8 port, and LB foot mounting interface.
The 32mm bore features a G1/8 port and M10x1.25 rod thread. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum force of 82kgf at 1.0MPa.
