This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X450SH, 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 SU63X450SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X450SH, which matches its bore, stroke, force and mounting.
The AirTAC SU63X450SH is a discontinued double-acting profile-type cylinder with a 63mm bore, 450mm stroke, and a high-temperature Viton H seal rated for 0 to 150 C. Generating 1559 N of push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore while sharing AirTAC SC-series mounting accessories. The direct replacement is the SAU63X450SH, matching the bore, stroke, 3/8" port, output force, and M16x1.5 rod thread.
The -S magnet on this legacy unit operated with CS1-B/DS1-B switches, but the SAU successor transitions to CMSG/DMSG/EMSG sensors. Additionally, the SAU family introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

The SAU63X450SH 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.
Pushes molded parts out of a heated press zone over the 450mm travel, requiring external guides to prevent rod bending.
Raises 79 kg loads vertically in packaging lines, necessitating a pilot-operated check valve to hold the load if air pressure drops.
To replace the SU63X450SH, order the SAU63X450SH direct equivalent, verifying the 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware (LB/FA/FB/CA/CB). Because this unit has a 450mm stroke, external guides are strongly recommended to prevent rod bending and side-load damage. If sizing alternatives, a 50mm bore yields 982 N push at 0.5 MPa, while an 80mm bore provides 2513 N. Note that the -H Viton seal supports 0-150 C environments. The -S magnet requires CMSG/DMSG/EMSG sensors on the new SAU body (legacy CS1-B/DS1-B will not fit). For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If valve integration is desired, explore the SAUF variant.
Replacement checklist
Yes, the SU63X450SH is discontinued. The direct replacement is the SAU63X450SH, which matches the 63mm bore, 450mm stroke, 3/8" port, force, and SC-series mounting. The SAU body is fully compatible, but the -S magnet now requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 63mm bore features a 3/8" port and M16x1.5 rod thread. It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
