This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175S, 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.

The AirTAC SU63-100 Standard Cylinder SU80X175S is a double-acting profile-type standard cylinder with a Ø80mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X175S, which matches its bore, stroke, force and mounting.
The AirTAC SU80X175S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 175 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU80X175S, a direct equivalent retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
The SAU upgrade transitions the -S magnet option to modern CMSG/DMSG/EMSG sensors, replacing the older CS1-B/DS1-B switches. It also introduces the SAUF variant with a built-in 4M solenoid valve, a feature the original SU line lacked.

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X175S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Secures large steel weldments during machining, utilizing the 2513 N push force at 0.5 MPa to prevent workpiece shifting under high cutting loads.
Actuates heavy diverter arms on conveyor lines, where the 128 kg vertical lift capacity and 175 mm stroke smoothly redirect loaded pallets.
Ejects formed metal parts from hydraulic presses, relying on adjustable 28 mm air cushions to decelerate the 25 mm rod at stroke end.
To replace this SU80X175S, order the SAU80X175S by confirming the 80 mm bore, 175 mm stroke, 3/8" port, M20x1.5 rod thread, and PT thread type. Because this SKU includes the -S magnet, you must switch from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. If sizing alternatives, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. A plain cylinder drifts without live air, so add an external rod lock or pilot-operated check valve for load holding. The SAUF built-in-valve option is available if you need self-switching. At 175 mm stroke, side-load alignment is manageable, but ensure proper guide rails to prevent rod bending.
Replacement checklist
Yes, the AirTAC SU80X175S is discontinued. The direct replacement is the SAU80X175S. It shares the identical 80 mm bore, 175 mm stroke, 2513 N output force, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X175S replacement — usually within 7-8 hours.
