This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1200, 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 SU63X1200 is a double-acting profile-type standard cylinder with a Ø63mm bore and 1200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1200, which matches its bore, stroke, force and mounting.
The AirTAC SU63X1200 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 1200 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. The direct replacement is the SAU63X1200, matching the bore, stroke, force, port and SC-series mounting.
This extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore. The SAU upgrade uses CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated option; this no-magnet SU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1200 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 SAU63X1200 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×1200 | 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.
Pushes heavy pallets laterally across a 1.2 m transfer line using the 1559 N push force at 0.5 MPa, requiring external guides to prevent rod bending over the long stroke.
Ejects formed metal parts from a press bed, utilising the adjustable 21 mm air cushions at both ends to decelerate the 20 mm rod smoothly at stroke limits.
To replace this SU63X1200, order the SAU63X1200. Confirm the 3/8" port, M16x1.5 rod thread, PT/G/NPT thread choice, and SC-series mounting (LB/FA/FB/CA/CB). Since this SKU lacks a magnet (-S), it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if you add the -S option. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. For the 1200 mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant offers a built-in 4M valve if needed.
Replacement checklist
Yes, the AirTAC SU63X1200 is discontinued. The direct replacement is the SAU63X1200. It shares the identical 63 mm bore, 1200 mm stroke, 1559 N force, 3/8" port, and SC-series mounting accessories. You can install the SAU without modifying the machine.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a 318 kgf maximum at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if you order the -S option.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X1200 replacement — usually within 7-8 hours.
