This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X200TC, 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 SI63X200TC
The AirTAC Airtac SI63 Standard Cylinder SI63X200TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X200TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X200TC
The AirTAC SI63X200TC is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 200mm stroke. It delivers 1559N push force at 0.5MPa via a G3/8 port. The direct replacement is the SAI63X200TC, matching the exact TC trunnion mount, interface, and output force.
Upgrading to the SAI brings an advanced two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot accept a sensor; legacy CS1-B/DS1-B switches only fit the -S version.

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 SAI63X200TC 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 SI63X200TC Is Used
Clamp Actuation
Secures heavy workpieces on machining fixtures using the 1559N push force at 0.5MPa, with the TC trunnion absorbing centerline stresses.
Package Diversion
Drives medium-duty sorting gates and pusher arms on assembly lines, benefiting from the 30-800mm/s speed range and 200mm travel.
Replacing the Airtac SI63 Standard Cylinder SI63X200TC with the SAI63X200TC
To replace the SI63X200TC, order the SAI63X200TC. It is dimensionally interchangeable per ISO 15552, retaining the 63mm bore, 200mm stroke, M16x1.5 rod thread, G3/8 port, and TC trunnion mounting. When sizing, neighbouring bores offer alternatives: a 50mm bore yields 982N push at 0.5MPa, while an 80mm bore yields 2513N. Because this plain cylinder lacks a magnet, it cannot take a sensor; if sensing is needed, select an SAI63X200TCS. For load holding, remember the air cushion only decelerates at stroke end and will not hold a load on air loss—use an external pilot check valve or the SAIL/BSAI lock variants. At 200mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X200TC
- ✓ 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 SI63X200TC FAQ
Yes, the AirTAC SI63X200TC is discontinued. The direct replacement is the SAI63X200TC. It matches the ISO 15552 mounting interface, 63mm bore, 200mm stroke, G3/8 port, and TC mount, fitting existing fixtures perfectly.
The 63mm bore features a G3/8 port and M16x1.5 rod thread. It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N at 0.9MPa, and a theoretical max of 318kgf at 1.0MPa.
