This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X765, 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 Airtac SU63-100 Standard Cylinder SU63X765 is a double-acting profile-type standard cylinder with a Ø63mm bore and 765mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X765, which matches its bore, stroke, force and mounting.
The AirTAC SU63X765 is a discontinued double-acting profile-type cylinder. It delivers 1559 N push and 1402 N pull at 0.5 MPa, scaling to a theoretical maximum of 318 kgf at 1.0 MPa. The direct replacement is the SAU63X765, matching the 63 mm bore, 765 mm stroke, 3/8" port, and SC-series mounting. This extruded aluminium body is shorter than an ISO 15552 cylinder of the same size.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. The SAU upgrade switches to current CMSG/DMSG/EMSG switches and adds a SAUF built-in valve option. Note that air cushions only decelerate; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X765 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 318 kgf | |
The SAU63X765 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.
Pushes heavy packages across a 765 mm transfer belt using its 1559 N push force at 0.5 MPa, requiring external guides to prevent rod bending.
Ejects moulded parts from a press using the 318 kgf maximum theoretical force, relying on adjustable 21 mm cushions for end-of-stroke deceleration.
To replace this discontinued SU63X765, order the SAU63X765. Confirm the 3/8" port (default PT thread), M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). If you previously used a magnet, the SAU requires CMSG/DMSG/EMSG sensors since this no-S SKU cannot take a switch. For loads exceeding 935 N, consider neighbouring bores (80 mm yields 2513 N push at 0.5 MPa). At 765 mm stroke, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, add an external pilot-operated check valve, as cushions only decelerate. The SAUF variant offers a built-in valve if needed.
Replacement checklist
Yes, the SU63X765 is discontinued. The direct replacement is the AirTAC SAU63X765. It matches the 63 mm bore, 765 mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting accessories. You can swap it directly without changing your mechanical footprint.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 318 kgf max at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor. If sensing is required, the SAU63X765 replacement supports CMSG/DMSG/EMSG switches (the SU line used legacy CS1-B/DS1-B).
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X765 replacement — usually within 7-8 hours.
