This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X700TC, 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 SI63X700TC
The AirTAC Airtac SI63 Standard Cylinder SI63X700TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X700TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X700TC
The AirTAC SI63X700TC is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 700mm stroke. Delivering 1559 N push force at 0.5 MPa via a G3/8 port, it is directly replaced by the SAI63X700TC. This direct upgrade shares the exact TC trunnion mount, M16x1.5 rod thread and dimensions.
The SAI features an upgraded piston seal with two Y-shaped elements for low start-up pressure. Note this SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAI63X700TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI63 Standard Cylinder SI63X700TC Is Used
Long-Stroke Material Push
Transfers parts across 700mm gaps on an assembly line, utilizing the 1559 N push force at 0.5 MPa to clear heavy billets reliably.
Trunnion-Mounted Press
Employs the ISO 15552 TC trunnion mount to pivot and apply 2182 N force at 0.7 MPa for seating components in heavy fixtures.
Pallet Diversion
Actuates a 700mm routing gate to redirect pallets, requiring an external guide to manage side-load during the extended stroke.
Replacing the Airtac SI63 Standard Cylinder SI63X700TC with the SAI63X700TC
To replace the SI63X700TC, order the SAI63X700TC. Verify the ISO 15552 TC trunnion interface, 63mm bore, 700mm stroke, G3/8 port (PT/G/NPT) and M16x1.5 thread. Because this 700mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. If sizing alternatives, neighbouring bores (50mm/80mm) offer 982 N / 2513 N push at 0.5 MPa. This plain cylinder drifts on air loss; for load holding use an external pilot check valve, or specify the SAIL (air-released lock) or BSAI (clamp-lock) variants. The SAIF variant adds a built-in 4M valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X700TC
- ✓ 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 SI63X700TC FAQ
Yes, the SI63X700TC is discontinued. The direct replacement is the SAI63X700TC. It is dimensionally interchangeable per ISO 15552, retaining the same 63mm bore, 700mm stroke, G3/8 port, TC trunnion mount and output force.
The 63mm bore uses a G3/8 port and features a 20mm rod with an M16x1.5 thread. It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Speed is 30-800 mm/s.
