This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175H, 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 SU80X175H
The AirTAC SU63-100 Standard Cylinder SU80X175H 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 SAU80X175H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X175H
The AirTAC SU80X175H is a discontinued double-acting profile cylinder with an 80mm bore, 175mm stroke, and a Viton H high-temperature seal rated for 0 to 150 C. Delivering 2513 N of push force at 0.5 MPa, its direct replacement is the SAU80X175H, which preserves the original 3/8 inch port, M20x1.5 rod thread, and SC-series mounting compatibility.
Because this is a high-temperature Viton H variant, it suits harsh environments. Note that this specific SKU lacks a magnet, so it cannot accept position sensors. The newer SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the legacy SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X175H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU80X175H 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 SU80X175H Is Used
Hot Stamp Press Ejection
Handles high-temperature ejection tasks on hot stamping presses, leveraging the Viton H seal to withstand ambient heat while delivering 2513 N of push force at 0.5 MPa.
Heated Product Diversion
Diverts warm molded components along processing lines where standard NBR seals would degrade, providing reliable 175mm stroke actuation in thermal environments.
Industrial Oven Doors
Actuates access doors on industrial ovens up to 150 C, offering robust 80mm bore performance and smooth deceleration via 28mm adjustable air cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X175H with the SAU80X175H
To replace the discontinued SU80X175H, order the SAU80X175H direct equivalent, verifying your 3/8 inch port, M20x1.5 rod thread, and SC-series mounting hardware. Since this SKU has no magnet (-S), it cannot support legacy CS1-B or DS1-B switches; if you require sensing on the SAU replacement, you must select the -S option and upgrade to the current CMSG, DMSG, or EMSG sensor family. For sizing alternatives, dropping to a 63mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100mm provides 3927 N. Remember that a standard cylinder does not hold load without live air; the 28mm adjustable cushions only decelerate the piston near stroke end, so install an external rod lock or pilot-operated check valve for secure load holding. If you need self-switching capability, explore the SAUF built-in-valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X175H
- ✓ 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 SU80X175H FAQ
Yes, the AirTAC SU80X175H is discontinued and end-of-life. The direct replacement is the SAU80X175H. It features the same 80mm bore, 175mm stroke, 3/8 inch port, Viton H high-temperature seal, and SC-series mounting accessories. You can install the SAU model directly into your existing fixture without modifying the mounting footprint.
This 80mm bore cylinder delivers 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 specific SKU lacks a magnet, it cannot accept position sensors. If sensing is required on the SAU replacement, you must order the -S version and use current CMSG, DMSG, or EMSG switches instead of the legacy CS1-B or DS1-B.
