This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X805S, 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 SU63X805S is a double-acting profile-type standard cylinder with a Ø63mm bore and 805mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X805S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X805S is a discontinued double-acting profile-type cylinder with an 805 mm stroke and a 63 mm bore. It delivers 1559 N of push force at 0.5 MPa (2182 N at 0.7 MPa) and features a 3/8" port with a 20 mm piston rod. AirTAC replaced this end-of-life unit with the SAU63X805S, a direct alternative retaining the exact same body dimensions, output, and SC-series mounting compatibility.
Because of the long 805 mm stroke, external guides are recommended to prevent rod bending under side loads. The -S magnet on this legacy model pairs with CS1-B/DS1-B switches, whereas the SAU replacement utilizes the current CMSG/DMSG/EMSG sensor family. Note that the air cushion only decelerates the piston; an external rod lock is required to hold a load.

The SAU63X805S 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 products across a 800 mm wide conveyor belt, utilizing the full 805 mm stroke with external guides to prevent rod bending.
Acts as a lateral ejector for palletized goods, leveraging the 1559 N push force at 0.5 MPa to slide heavy loads onto an adjacent lane.
To replace the discontinued SU63X805S, order the SAU63X805S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. If your application needs a smaller bore, the 50 mm version provides 982 N push at 0.5 MPa; for higher force, the 80 mm bore yields 2513 N. Because this is an 805 mm stroke, you must use external guides to prevent rod bending and premature seal wear. The -S suffix means a magnet is present: expect to upgrade from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAU. For load holding on air loss, add a pilot-operated check valve or external rod lock, as the cushion only decelerates. If you want to simplify plumbing, the SAUF variant integrates a 4M solenoid valve directly on the cylinder body.
Replacement checklist
Yes, the AirTAC SU63X805S is discontinued. The direct replacement is the SAU63X805S. It shares the identical 63 mm bore, 805 mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting, so it drops directly into the same application.
The 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf theoretical max at 1.0 MPa. The -S magnet on the SU worked with 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 SAU63X805S replacement — usually within 7-8 hours.
