This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175TC, 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 SU80X175TC 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 SAU80X175TC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X175TC is a discontinued double-acting profile-type cylinder with an 80mm bore and 175mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating via a 3/8 port with a 25mm rod. AirTAC replaced this EOL unit with the SAU80X175TC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement requires current CMSG/DMSG/EMSG switches rather than legacy CS1-B/DS1-B parts. The SAU family also introduces a SAUF valve-integrated option absent in the SU line.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X175TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X175TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×175 | Stroke length in mm. |
| -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.
Uses the TC mount to push heavy pallets sideways on a packaging line, relying on the 2513N thrust at 0.5MPa to overcome friction.
Drives the opening and closing of material handling roller gates where the compact profile body saves space compared to standard ISO cylinders.
Ejects formed metal parts from a press bed, utilizing the 28mm adjustable air cushions to decelerate the 25mm rod at stroke ends.
To replace the SU80X175TC, order the SAU80X175TC, confirming the 80mm bore, 175mm stroke, 3/8 port, M20x1.5 rod thread, and TC mounting are retained. This non-magnetic SKU cannot support switches; if you need position detection, the SAU upgrade uses CMSG/DMSG/EMSG sensors. For higher flow control, explore the SAUF built-in-valve variant. Sizing context: a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
Yes, the SU80X175TC is discontinued. The direct replacement is the SAU80X175TC. It shares the same 80mm bore, 175mm stroke, 3/8 port, 513kgf max force, and TC mounting, fitting the same application directly.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa it pushes 3518N, with a theoretical max of 513kgf at 1.0MPa. It cannot hold a load without live air—the cushion only decelerates—so use an external rod lock for vertical holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X175TC replacement — usually within 7-8 hours.
