This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1150S, 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.
Airtac SU63-100 Standard Cylinder SU63X1150S
The AirTAC SU63-100 Standard Cylinder SU63X1150S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1150S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1150S
The AirTAC SU63X1150S is a discontinued double-acting profile-type cylinder with a 63mm bore and 1150mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, operating at 30-800mm/s through a 3/8" port. AirTAC replaced this end-of-life unit with the SAU63X1150S, a direct upgrade retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU replacement modernizes the sensor groove, switching from the legacy CS1-B/DS1-B switches used on this -S SKU to the current CMSG/DMSG/EMSG family. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1150S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X1150S 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.
Where the Airtac SU63-100 Standard Cylinder SU63X1150S Is Used
Long-Reach Diversion
Actuates routing gates on extended conveyor lines where the 1150mm stroke shifts heavy pallets laterally between processing lanes.
High-Bay Pusher
Uses the 1559N push force at 0.5MPa to eject totes from deep storage racks, requiring external guides to manage the long rod extension.
Material Transfer Arm
Drives extended transfer carriages in automated assembly, benefiting from the compact profile body to save machine footprint.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1150S with the SAU63X1150S
To replace this discontinued SU63X1150S, order the SAU63X1150S direct equivalent, confirming the 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Because the 1150mm stroke exceeds the 1500mm standard maximum, it is a nonstandard stroke requiring verification. At 0.5MPa, the 63mm bore yields 1559N push; if undersizing, a 50mm bore provides 982N, and if oversizing, an 80mm bore offers 2513N. The -S magnet means you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this long 1150mm stroke, use an external guide to prevent rod bending and side-load damage. A plain cylinder drifts without air; use an external rod lock or pilot-operated check valve for load holding. The SAUF variant adds a built-in 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1150S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU63-100 Standard Cylinder SU63X1150S FAQ
Yes, the AirTAC SU63X1150S is discontinued. The direct replacement is the SAU63X1150S. It shares the same 63mm bore, 1150mm stroke, 3/8" port, output force, and SC-series mounting, but the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
At 0.5MPa it provides 1559N push and 1402N pull; at 0.7MPa push is 2182N; at 0.9MPa push is 2805N; with a theoretical max of 318kgf at 1.0MPa. Note that the air cushion only decelerates the load; it does not hold position on air loss, so an external rod lock is required for holding.
