This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X80TC, 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 SU63X80TC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X80TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X80TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X80TC
The AirTAC SU63X80TC is a discontinued double-acting profile-type cylinder featuring an 80 mm stroke and a 63 mm bore. It delivers 1559 N of push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X80TC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
This compact extruded-aluminium body is shorter than a same-bore ISO 15552 unit. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. The SAU successor adds a built-in valve option (SAUF) the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X80TC 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 SAU63X80TC 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 SU63X80TC Is Used
Package Diverting
Drives a TC-mounted diverting arm on a packaging line, using the 1559 N push force at 0.5 MPa to redirect heavy cartons reliably.
Pallet Stopping
Acts as a robust end-stop for incoming pallets on a roller conveyor, absorbing kinetic energy via its adjustable 21 mm air cushions.
Clamp Actuation
Secures medium-weight workpieces in a machining fixture, providing stable clamping without requiring continuous load-holding pressure.
Replacing the Airtac SU63-100 Standard Cylinder SU63X80TC with the SAU63X80TC
To replace this SU63X80TC, order the SAU63X80TC and verify your 3/8" port, M16x1.5 rod thread, and TC mounting accessory. Since this SKU has no magnet, it cannot support sensing; if you need position detection on the new unit, add an -S suffix and note that the SAU uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, the 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa; neighbouring bores (50 mm / 80 mm) offer 982 N and 2513 N push respectively at the same pressure. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU63X80TC
- ✓ 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 SU63X80TC FAQ
Yes, the AirTAC SU63X80TC is discontinued and end-of-life. The direct replacement is the SAU63X80TC. It matches the original 63 mm bore, 80 mm stroke, 1559 N output force, 3/8" port, and TC mounting interface, fitting the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, and the theoretical maximum is 318 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept a sensor; if sensing is required on the SAU replacement, an -S version must be ordered, which uses CMSG/DMSG/EMSG switches.
