This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1500S, 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 SU63X1500S
The AirTAC SU63-100 Standard Cylinder SU63X1500S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1500S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1500S
The AirTAC SU63X1500S is a discontinued double-acting profile-type cylinder with a 63mm bore and 1500mm stroke. Delivering 1559N push at 0.5MPa via a 3/8" port, it is replaced directly by the SAU63X1500S. This upgrade retains the exact body dimensions, force, and SC-series mounting.
The SAU direct offers the new SAUF valve-integrated variant and upgrades the -S magnet from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1500S 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 SAU63X1500S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU63X1500S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×1500 | 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.
Where the Airtac SU63-100 Standard Cylinder SU63X1500S Is Used
Long-Reach Transfer
Pushes heavy pallets along a 1500mm conveyor path using the 1559N @0.5MPa thrust, guided externally to prevent rod bending.
Material Ejection
Ejects molded parts from a large press bed, relying on adjustable 21mm cushions to decelerate the 63mm piston at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1500S with the SAU63X1500S
To replace this SU63X1500S, order the SAU63X1500S direct, confirming the 3/8" port, M16x1.5 rod thread, and SC-series mounting. The -S magnet requires upgrading to CMSG/DMSG/EMSG sensors. Sizing both ways: a 50mm bore yields 982N [email protected], while an 80mm bore yields 2513N. For this 1500mm long stroke, use external guides to prevent rod bending and side-load damage. The cylinder will not hold a load without air; add a pilot-operated check valve. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1500S
- ✓ 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 SU63X1500S FAQ
Yes, the AirTAC SU63X1500S is discontinued. The direct replacement is the SAU63X1500S, which shares the same 63mm bore, 1500mm stroke, 3/8" port, output force, and SC-series mounting.
The 63mm bore provides 1559N push and 1402N pull @0.5MPa, 2182N @0.7MPa, and a 318kgf max @1.0MPa. The -S magnet on the old SU worked with CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
