This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X1560TC, 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 SI63X1560TC
The AirTAC SI63 Standard Cylinder SI63X1560TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1560mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X1560TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X1560TC
The AirTAC SI63X1560TC is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 1560 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, scaling to 2805 N at 0.9 MPa. The direct replacement is the SAI63X1560TC, matching the TC trunnion mount, G3/8 port, and M16x1.5 rod thread. This 1560 mm length is a non-standard made-to-order stroke exceeding the 1500 mm bore maximum, requiring external guides to prevent rod bending. Because this SKU lacks the -S magnet, it cannot accept position sensors.
Upgrading to the SAI brings an advanced two Y-shaped one-way piston seal for low start-up pressure and extended life, while retaining the exact ISO 15552 mounting dimensions. Note that a standard cylinder drifts on air loss; for load holding, explore the SAIL or BSAI lock variants, or use an external pilot check valve.

Where the Airtac SI63 Standard Cylinder SI63X1560TC Is Used
Long-Stroke Material Transfer
Pushes heavy pallets between machining centers over a 1560 mm span, utilizing the 1559 N push force at 0.5 MPa while external rails support the load.
High-Bay Pusher Arm
Actuates a storage diverter arm requiring a long extension; the TC trunnion mount handles the pivot stress of the extended 63 mm bore cylinder.
Automated Assembly Line Indexing
Shifts large automotive subframes down an assembly line, relying on the 1402 N pull force at 0.5 MPa to retract the 1560 mm stroke mechanism.
Replacing the Airtac SI63 Standard Cylinder SI63X1560TC with the SAI63X1560TC
To replace the SI63X1560TC, order the SAI63X1560TC to guarantee the same ISO 15552 interface, 63 mm bore, 1560 mm stroke, G3/8 port, and TC trunnion mounting. This stroke is non-standard (exceeding the 1500 mm maximum), so expect a made-to-order lead time and definitely specify external guide rails to absorb side loads and prevent rod bending over that distance. If you need to adjust force, neighboring bores are 50 mm (982 N push @0.5 MPa) and 80 mm (2513 N push @0.5 MPa). Because this specific SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, request an SAI with a magnet. A plain cylinder will not hold a load without live air—the cushion only decelerates—so for vertical or suspended loads, specify the SAIL lock, BSAI clamp-lock, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X1560TC
- ✓ 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 SI63X1560TC FAQ
Yes, the AirTAC SI63X1560TC is discontinued. The direct replacement is the SAI63X1560TC. It is dimensionally interchangeable per ISO 15552, retaining the exact same 63 mm bore, 1560 mm stroke, G3/8 port, and TC trunnion mounting interface. The SAI simply upgrades the piston seal to a two Y-shaped one-way element for longer life.
The 63 mm bore features a 20 mm rod, M16x1.5 thread, G3/8 port, and 30 mm adjustable cushions. It operates at 30-800 mm/s. Force ratings are: 1559 N push and 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. Note that 1560 mm is a non-standard stroke exceeding the 1500 mm maximum.
