This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X50SH, 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 SU80X50SH is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X50SH, which matches its bore, stroke, force and mounting.
The AirTAC SU80X50SH is a discontinued double-acting profile-type cylinder with an 80mm bore, 50mm stroke, and a Viton H high-temperature seal rated for 0-150 C. Delivering 2513 N of push force at 0.5 MPa, it features a 3/8" port and a Ø25 mm piston rod. AirTAC replaced this end-of-line unit with the SAU80X50SH, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches used on this -S magnet model. The new SAUF variant even integrates a built-in 4M solenoid valve, an option the SU line never offered. Remember, the adjustable air cushion only decelerates the piston; it does not hold the load if air pressure drops.

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.
Handles the ejection of molded parts from hot stamping presses, utilizing the Viton H seal to withstand ambient radiant heat up to 150 C while delivering 2513 N of push force.
Actuates diverter arms on oven exit conveyors, where the compact profile body fits tight machinery guards and the 50mm stroke rapidly redirects product.
To replace this SU80X50SH, order the SAU80X50SH, confirming the 80mm bore, 50mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting hardware are identical. Because this SKU includes the -S magnet, you must upgrade your sensing setup: the SAU body uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reed sensors. The -H Viton seal correctly matches your 0-150 C high-temperature environment. When sizing, the 80mm bore yields 2513 N push and 2268 N pull at 0.5 MPa; if you need less force, stepping down to a 63mm bore provides 1559 N push. A plain double-acting cylinder drifts when air is removed, so fit an external rod lock or pilot-operated check valve if the load must be held. The SAUF valve-integrated version is also worth considering if you want to simplify piping.
Replacement checklist
Yes, the AirTAC SU80X50SH is discontinued. The direct replacement is the SAU80X50SH. It shares the identical 80mm bore, 50mm stroke, 3/8" port, Viton H high-temp seal, and SC-series mounting. The only change is that your legacy CS1-B/DS1-B sensors must be replaced with CMSG/DMSG/EMSG switches on the new SAU model.
This double-acting cylinder features a 3/8" port and a Ø25 mm piston rod. At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa the push force is 3518 N, and the theoretical maximum output is 513 kgf at 1.0 MPa. The adjustable air cushion stroke is 28 mm at each end.
