This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X200SLB, 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 SI32X200SLB
The AirTAC SI32 Standard Air Cylinder SI32X200SLB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X200SLB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32X200SLB
The AirTAC SI32X200SLB is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 200mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is replaced by the SAI32X200SLB. This direct upgrade shares identical mounting, force, and port sizes, fitting existing LB foot brackets seamlessly.
The SAI replacement features an upgraded piston seal with two Y-shaped elements for low start-up pressure and long life. The SAI family also introduces SAIL lock, SAIF valve, and BSAI clamp variants absent in the SI line. Your -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI uses current switches.

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 SI32X200SLB Is Used
Small Part Ejection
Uses the 402N push force to reliably knock small molded parts out of fixtures on an automated press line.
Package Diverting
Actuates a 200mm stroke diverter arm to route lightweight cardboard boxes on a packaging conveyor.
Gripper Actuation
Opens and closes pneumatic grippers handling 20kg vertical loads in material handling stations.
Replacing the Airtac SI32 Standard Air Cylinder SI32X200SLB with the SAI32X200SLB
To replace the SI32X200SLB, order the SAI32X200SLB. It drops into the same LB foot mounting fixture with identical ISO 15552 interface dimensions, 32mm bore, 200mm stroke, M10x1.25 rod thread, and G1/8 port. If you need more force, neighboring bores like the 40mm offer 628N push at 0.5MPa; if less is required, check smaller profiles. For any stroke over 300mm, use a guide to prevent rod bending and side-load wear. Remember, a standard cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32X200SLB
- ✓ 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 SI32X200SLB FAQ
Yes, the SI32X200SLB is discontinued. The direct replacement is the SAI32X200SLB. It shares the same ISO 15552 mounting interface, 32mm bore, 200mm stroke, G1/8 port, and output force, fitting existing LB foot brackets perfectly.
This double-acting cylinder uses a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and 724N push at 0.9MPa. The theoretical maximum force is 82kgf at 1.0MPa.
