This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X140H, 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 SU80X140H is a double-acting profile-type standard cylinder with a Ø80mm bore and 140mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X140H, which matches its bore, stroke, force and mounting.
The AirTAC SU80X140H is a discontinued double-acting profile-type cylinder with an 80mm bore, 140mm stroke, and high-temperature Viton H (FKM) seals rated for 0 to 150 C. It delivers 2513 N push and 2268 N pull at 0.5 MPa, utilizing a 25mm rod and 3/8" port. AirTAC replaced this end-of-life unit with the SAU80X140H, a direct alternative retaining the exact body, force, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in 4M solenoid valve option absent from the SU line. Note this non-magnet SKU cannot accept a sensor, and the cylinder will drift without live air—use an external rod lock for holding.

| Max (@1.0 MPa) | 513 kgf | |
The SAU80X140H 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.
Ejecting molded parts from hot zones up to 150 C using the Viton H seal, delivering 2513 N push at 0.5 MPa to clear heavy components reliably.
Applying 3518 N of force at 0.7 MPa for stamping or forming operations, utilizing the 140mm stroke to cycle medium-duty tooling.
Routing heavy pallets on a 3/8" port pneumatic line, safely handling working loads near 1508 N without requiring external boosters.
To replace this SU80X140H, order the SAU80X140H direct equivalent, verifying the 80mm bore, 140mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because this is a non-magnet (-H only) SKU, it cannot accept a sensor; if detection is needed, a separate -S SAU model is required, which uses CMSG/DMSG/EMSG switches rather than legacy CS1-B/DS1-B. For force context, stepping down to a 63mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100mm provides 3927 N. The Viton H seal handles 0-150 C environments. Since the cushion only decelerates and the piston drifts on air loss, apply a pilot-operated check valve or rod lock for load holding. The SAUF valve-integrated variant is available if local switching is desired.
Replacement checklist
Yes, the AirTAC SU80X140H is discontinued. The direct replacement is the SAU80X140H. It matches the 80mm bore, 140mm stroke, 3/8" port, 2513 N force, and SC-series mounting, but uses current CMSG/DMSG/EMSG sensors and offers a SAUF built-in valve option.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The Viton H seal allows operation from 0 to 150 C. As a non-magnet SKU, it cannot accept sensors, and it will not hold a load without live air.
