This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1630STC, 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 SU80X1630STC
The AirTAC SU63-100 Standard Cylinder SU80X1630STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 1630mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1630STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1630STC
The AirTAC SU80X1630STC is a discontinued double-acting profile-type cylinder with an 80mm bore and a 1630mm stroke. Because this stroke exceeds the 1500mm standard maximum for this bore, it was produced as a non-standard, made-to-order unit. It delivers a thrust of 2513 N at 0.5 MPa and features a 3/8" port. AirTAC replaced the SU line with the SAU family, making the SAU80X1630STC the direct replacement. It shares the same extruded aluminum body, bore, stroke, output force, port size, and SC-series TC mounting accessories.
Buyers gain specific advantages by moving to the SAU. The original -S magnet on this unit functioned with legacy CS1-B/DS1-B switches, but the SAU replacement utilizes the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU series never offered.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X1630STC 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 SU80X1630STC Is Used
Long-Reach Transfer
Pushes heavy pallets along a 1.6m conveyor line where the 2513 N thrust at 0.5 MPa handles substantial accumulated weight over the extended distance.
High-Bay Extraction
Reaches deep into storage racks to extract 128 kg vertical loads, utilizing the full 1630mm stroke while requiring external guides to prevent rod bending.
Material Ejection
Cycles long-stroke ejection arms on a manufacturing floor, relying on the TC mount to secure the compact profile body during rapid 30-800 mm/s movements.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1630STC with the SAU80X1630STC
To replace this discontinued SU80X1630STC, order the SAU80X1630STC. Confirm the 80mm bore, the 1630mm non-standard made-to-order stroke, the 3/8" port, the M20x1.5 rod thread, and the SC-series TC mounting interface. Because this unit has an -S magnet, you must upgrade your sensors: the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG switches on the SAU. When sizing, check neighboring bores and forces (this 80mm bore provides 2513 N push at 0.5 MPa or 3518 N at 0.7 MPa). A plain cylinder does not hold a load without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve for held loads. Finally, at 1630mm, the rod is highly susceptible to bending; use external guides to prevent side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1630STC
- ✓ 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 SU80X1630STC FAQ
Yes, the SU80X1630STC is discontinued. The direct replacement is the AirTAC SAU80X1630STC. It matches the original 80mm bore, 1630mm non-standard stroke, 3/8" port, output force, and SC-series TC mounting. You simply order the SAU equivalent.
The 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Because this model includes an -S magnet, note that the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
