This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175STC, 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 SU80X175STC 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 SAU80X175STC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X175STC is a discontinued double-acting profile cylinder with an 80mm bore and 175mm stroke. The direct replacement is the SAU80X175STC, retaining the same 3/8" port, M20x1.5 rod thread, and 28mm cushions.
Upgrading to the SAU keeps the compact extruded aluminium body and TC mounting interface, but the legacy CS1-B/DS1-B sensors on this -S model must change to the current CMSG/DMSG/EMSG family. The SAU line also introduces the SAUF built-in 4M solenoid valve variant, a self-switching option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X175STC 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 SAU80X175STC 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.
Provides the 2513N push force needed to divert heavy pallets on a 3/8" ported pneumatic line without requiring a full ISO 15552 footprint.
Ejects formed parts from a press using the 28mm adjustable air cushions to decelerate the 25mm rod smoothly at the end of each 175mm stroke.
To replace this discontinued SU80X175STC, order the SAU80X175STC direct equivalent, verifying the 80mm bore, 175mm stroke, 3/8" port, and TC mounting accessory are retained. Because this SKU includes the -S magnet, note that your existing CS1-B/DS1-B switches must be swapped to CMSG/DMSG/EMSG sensors on the new cylinder. Sizing both ways: a 63mm bore provides 1559N push at 0.5MPa, while a 100mm bore offers 3927N, giving you room to adjust if the 2513N output is borderline. Remember that a standard cylinder drifts without live air, as the 28mm cushions only decelerate the piston; use an external rod lock or pilot-operated check valve for secure load holding. At 175mm stroke, side-load risks are low, but always ensure proper guide alignment to prevent rod bending.
Replacement checklist
Yes, the SU80X175STC is discontinued. The direct replacement is the SAU80X175STC, which matches the 80mm bore, 175mm stroke, 3/8" port, and TC mounting interface. You must upgrade the -S magnet sensors from the old CS1-B/DS1-B to the new CMSG/DMSG/EMSG family.
At 0.5MPa it pushes 2513N and pulls 2268N. At 0.7MPa push is 3518N, and at 0.9MPa it is 4523N. The theoretical maximum is 513kgf at 1.0MPa. It operates at 30-800mm/s, uses a 25mm rod with M20x1.5 thread, and has 28mm adjustable cushions at both ends.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X175STC replacement — usually within 7-8 hours.
