This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X110S, 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 SU63X110S is a double-acting profile-type standard cylinder with a Ø63mm bore and 110mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X110S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X110S is a discontinued double-acting profile cylinder with a 63mm bore and 110mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same size while sharing AirTAC SC-series mounting accessories.
The direct replacement is the SAU63X110S, which preserves the original bore, stroke, output force, port size, and mounting hardware. Two key upgrades exist: the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches found on this SU -S model, and the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X110S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X110S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×110 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Actuates routing gates on 24V packaging lines where the 110mm stroke provides ample travel to redirect parcels without excessive cycle time.
Deploys heavy-duty end stops on gravity roller conveyors, using the 1559 N push force at 0.5 MPa to halt accumulated pallets safely.
Secures aluminum extrusions during CNC machining operations, relying on the 20mm piston rod and compact profile body to fit tight tooling envelopes.
To replace this SU63X110S, order the SAU63X110S and verify your 3/8" port threads (PT, G, or NPT) alongside your SC-series mounting brackets (LB, FA, FB, CA, CB, or TC). Because this SKU includes the -S magnet, you must swap your old CS1-B/DS1-B reed switches for the modern CMSG/DMSG/EMSG sensor family. If sizing a new application, the 63mm bore pushes 1559 N at 0.5 MPa; stepping down to a 50mm bore yields 982 N, while an 80mm bore provides 2513 N. Note that a plain cylinder drifts on air loss—the 21mm adjustable cushions only decelerate near stroke end, so install an external rod lock or pilot-operated check valve for held loads. If you need automated self-switching, explore the SAUF valve-integrated option.
Replacement checklist
Yes, the AirTAC SU63X110S is discontinued. The direct replacement is the SAU63X110S, which matches the 63mm bore, 110mm stroke, 3/8" port, force, and SC-series mounting. You simply order the SAU equivalent.
The 63mm bore generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X110S replacement — usually within 7-8 hours.
