This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X450STC, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU63-100 Standard Cylinder SU63X450STC
The AirTAC SU63-100 Standard Cylinder SU63X450STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X450STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X450STC
The AirTAC SU63X450STC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 450 mm stroke. Delivering 1559 N push force at 0.5 MPa (318 kgf max at 1.0 MPa), it features a 3/8" port and an extruded aluminum body that is shorter than an ISO 15552 unit of the same bore. AirTAC replaced this EOL unit with the SAU63X450STC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF variant with a built-in 4M solenoid valve the original SU lacked. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X450STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU63X450STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU63-100 Standard Cylinder SU63X450STC Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using the 1559 N push force at 0.5 MPa, with TC mounting allowing rigid center-trunnion pivot to absorb angular motion.
Press Ejection
Ejects formed metal components from a hydraulic press, requiring the 318 kgf maximum theoretical output and the 21 mm adjustable end cushions to soften stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU63X450STC with the SAU63X450STC
To replace this discontinued SU63X450STC, order the SAU63X450STC direct: it matches the 63 mm bore, 450 mm stroke, 3/8" port, M16x1.5 rod thread, and TC mounting interface. If your fixture lacks a magnet, a no-S SKU cannot accept any sensor. When sizing both ways, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. Because the stroke is 450 mm, prevent rod bending by supporting the load with an external guide to avoid excessive side-load. If you need true load holding on air loss, add a pilot-operated check valve or external rod lock, as the adjustable cushion only decelerates. For faster cycling, the SAUF variant integrates a valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU63X450STC
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU63X450STC FAQ
Yes, the SU63X450STC is discontinued. The direct replacement is the SAU63X450STC. It shares the identical 63 mm bore, 450 mm stroke, 3/8" port, output force, and SC-series TC mounting, so it drops right into the same application.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf max at 1.0 MPa. Because this is an -S model with a magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
