This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X160H, 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 SI63 Standard Cylinder SI63X160H
The AirTAC Airtac SI63 Standard Cylinder SI63X160H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X160H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X160H
The AirTAC SI63X160H is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 160 mm stroke. It delivers 1559 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the SAI63X160H, matching the interface, force, and port exactly.
Because this SKU lacks an -S magnet, it cannot accept a CS1-B/DS1-B sensor. The SAI upgrade uses two Y-shaped piston seals for low start-up pressure. For high heat, the -H Viton seal allows 0-150 C operation.

Where the Airtac SI63 Standard Cylinder SI63X160H Is Used
Hot Stamp Ejection
Uses the -H Viton seal to withstand 150 C radiated heat while pushing 1559 N to eject stamped parts from a press bed.
High-Temp Diverting
Executes 160 mm strokes to divert heavy packages on an oven-adjacent line, relying on the robust G3/8 pneumatic supply.
Clamp Actuation
Provides 2182 N of clamping force at 0.7 MPa to secure metal workpieces near thermal processing equipment.
Replacing the Airtac SI63 Standard Cylinder SI63X160H with the SAI63X160H
To replace the SI63X160H, order the SAI63X160H. Verify the ISO 15552 mounting interface, G3/8 port, M16x1.5 rod thread, and 30 mm cushions. Since this is a no-S SKU, it cannot hold a sensor. For load holding, note that a plain cylinder drifts on air loss; use an external pilot check valve or the SAIL/BSAI lock variant. At 0.5 MPa, the 63 mm bore yields 1559 N push; sizing down to 50 mm gives 982 N, while sizing up to 80 mm provides 2513 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X160H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI63 Standard Cylinder SI63X160H FAQ
Yes, the SI63X160H is discontinued. The direct replacement is the SAI63X160H. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 160 mm stroke, G3/8 port, and mounting interface.
The 63 mm bore features a G3/8 port and delivers 1559 N push / 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Speed is 30-800 mm/s.
