This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X30S, 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 SU63X30S is a double-acting profile-type standard cylinder with a Ø63mm bore and 30mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X30S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X30S is a discontinued double-acting profile-type cylinder featuring a 63 mm bore, 30 mm stroke, and a piston magnet for position sensing. AirTAC replaced this legacy unit with the SAU63X30S, a direct alternative retaining the exact bore, stroke, output force, 3/8" port, and SC-series mounting.
The compact extruded aluminum body is shorter than a same-bore ISO 15552 cylinder. Because this SU model includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. Furthermore, the SAU family introduces the SAUF variant with a built-in 4M solenoid valve, an integrated self-switching option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×30 | 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.
Ideal for holding heavy metal castings during machining, utilizing the 1559 N push force to secure parts firmly against a fixture bed.
Provides robust 30 mm actuation to push heavy cartons off a main production line onto a secondary packaging routing lane.
Acts as a high-strength physical stop block to halt pallets at a specific workstation, handling the impact via adjustable air cushions.
To replace this SU63X30S, order the SAU63X30S, verifying the 63 mm bore, 30 mm stroke, M16x1.5 rod thread, and 3/8" port (default PT, with G or NPT available). Retain your existing SC-series mounting brackets, as the profile body and accessory dimensions are unchanged. If sizing alternatives, the neighboring 50 mm bore offers 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. For the -S magnet option, note the required sensor family change from legacy CS1-B/DS1-B to the modern CMSG/DMSG/EMSG switches on the SAU. A plain cylinder does not hold load without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve for vertical holding. If pneumatics need local control, explore the SAUF valve-integrated variant.
Replacement checklist
Yes, the SU63X30S is discontinued and end-of-life. The direct replacement is the AirTAC SAU63X30S. It shares the identical 63 mm bore, 30 mm stroke, output force, 3/8" port, and SC-series mounting, so it fits the same application directly.
It delivers 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, it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X30S replacement — usually within 7-8 hours.
