This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1500STC, 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 SU80X1500STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 1500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1500STC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X1500STC is a discontinued double-acting profile-type cylinder featuring an 80mm bore, 1500mm stroke, and a built-in magnet for legacy CS1-B/DS1-B switches. It delivers 2513N push force at 0.5MPa and uses a 3/8" port with M20x1.5 rod threading.
The direct replacement is the SAU80X1500STC, retaining the same bore, stroke, output force, 3/8" port, and SC-series TC mounting. The SAU upgrade switches to modern CMSG/DMSG/EMSG sensors and introduces the SAUF built-in 4M solenoid valve variant.

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.
Drives heavy pallets across extended conveyor sections where 1500mm travel and 2513N push force at 0.5MPa are required for continuous packaging lines.
Acts as a depalletizing pusher at elevated heights, utilizing the TC mount and 80mm bore to shift loads safely up to a 1508N working threshold.
Indexes heavy automotive sub-assemblies between stations, relying on adjustable 28mm cushions to decelerate high-mass movements at stroke ends.
To replace this SU with the SAU80X1500STC, confirm the 80mm bore, 1500mm stroke, 3/8" port, M20x1.5 thread, and TC mounting interface. Because the original has a magnet (-S), note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For load sizing, neighbouring bores are 63mm (1559N [email protected]) and 100mm (3927N [email protected]). A plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock for holding. At 1500mm stroke, prevent rod bending by guiding the load externally. If faster actuation is needed, consider the SAUF valve-integrated option.
Replacement checklist
Yes, the SU80X1500STC is discontinued. The direct replacement is the SAU80X1500STC, which matches the 80mm bore, 1500mm stroke, 2513N force, 3/8" port, and TC mounting. The SAU body is identical, but its magnet uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
This 80mm bore cylinder has a 3/8" port and delivers 2513N push / 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa. The rod is 25mm with an M20x1.5 thread, and speed ranges 30-800mm/s.
