This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X15S, 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 SU63X15S is a double-acting profile-type standard cylinder with a Ø63mm bore and 15mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X15S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X15S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 15 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X15S, a direct upgrade retaining the exact body, stroke, output force, and SC-series mounting footprint.
The SAU replacement modernizes the sensor groove: your legacy CS1-B/DS1-B switches switch to CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M solenoid valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X15S 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 SAU63X15S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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.
Ideal for holding heavy workpieces in machining fixtures where a compact 15 mm stroke and 1559 N force securely lock parts for milling or drilling operations.
Provides robust 63 mm bore push force to snap heavy-duty conveyor sorting gates into position rapidly, handling the high impact of package routing.
Acts as a heavy-duty pneumatic stop in pallet handling lines, using its 15 mm stroke to rise and halt 79 kg loads safely without excessive retraction space.
To replace this SU63X15S, order the SAU63X15S by confirming the 63 mm bore, 15 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the SAU body. If you need higher force, the 80 mm bore provides 2513 N push at 0.5 MPa; if lower force is acceptable, the 50 mm bore offers 982 N. For any load holding, remember the air cushion only decelerates; install an external rod lock or pilot-operated check valve to prevent drift on air loss. If automated actuation is needed, consider the SAUF variant with its integrated valve.
Replacement checklist
Yes, the AirTAC SU63X15S is discontinued and end-of-life. The direct replacement is the SAU63X15S. It shares the identical 63 mm bore, 15 mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull force, rising to 2182 N push at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches used on the SU are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X15S replacement — usually within 7-8 hours.
