This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X75TC, 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 SU63X75TC
The AirTAC SU63-100 Standard Cylinder SU63X75TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X75TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X75TC
The AirTAC SU63X75TC is a discontinued double-acting profile-type cylinder with a 63 mm bore, 75 mm stroke, and a 3/8" port. It delivers 1559 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU63X75TC, a direct replacement retaining the exact bore, stroke, output force, port size, and TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade introduces the SAUF variant with a built-in valve, which the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X75TC 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 SAU63X75TC 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 SU63X75TC Is Used
Carton Diverting
Drives a 75 mm stroke diverter arm on a packaging line, using the 1559 N push force at 0.5 MPa to push heavy cardboard cartons reliably onto secondary tracks.
Pallet Stopper Gate
Acts as a pneumatic stop for roller conveyors handling loaded pallets, with the TC mount providing a stable pivot and the compact profile saving overhead space.
Clamp Actuation
Secures medium-weight aluminum castings during CNC machining, delivering 2182 N of clamping thrust at 0.7 MPa within a tight 75 mm clamping envelope.
Replacing the Airtac SU63-100 Standard Cylinder SU63X75TC with the SAU63X75TC
To replace this discontinued SU63X75TC, order the SAU63X75TC keeping the 63 mm bore, 75 mm stroke, 3/8" port, M16x1.5 rod thread, and TC mounting. If stepping up or down, adjacent bores are 50 mm (982 N push @0.5 MPa) and 80 mm (2513 N push @0.5 MPa). This non-magnetic SKU cannot hold a position switch; if sensing is needed, specify an SAU with a magnet and update to CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss—the cushion only decelerates—so use a rod lock for held loads. For high-cycle automation, consider the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X75TC
- ✓ 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 SU63X75TC FAQ
Yes, the SU63X75TC is discontinued. The direct replacement is the SAU63X75TC. It shares the identical 63 mm bore, 75 mm stroke, 3/8" port, output force, and TC mounting hardware, so it bolts right in. The SAU also adds the option of a built-in valve (SAUF variant) the SU lacked.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N; at 0.9 MPa it pushes 2805 N; with a theoretical max of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a position switch; legacy SU sensors were CS1-B/DS1-B, while the SAU replacement uses CMSG/DMSG/EMSG switches.
