This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X800SH, 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 SU63X800SH
The AirTAC SU63-100 Standard Cylinder SU63X800SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X800SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X800SH
The AirTAC SU63X800SH is a discontinued double-acting profile cylinder with an 800 mm stroke and a 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa, making your direct replacement the SAU63X800SH. This upgrade retains the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting, ensuring a seamless physical fit. The original -H seal specifies high-temperature Viton FKM, allowing operation up to 150 C.
Two functional shifts occur with the SAU: the legacy CS1-B/DS1-B switches used by this -S magnet are replaced by current CMSG/DMSG/EMSG sensors, and the new SAUF variant offers a built-in 4M solenoid valve the SU line never had. Note that an 800 mm stroke demands external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X800SH 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 SAU63X800SH 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 SU63X800SH Is Used
Long-Stroke Diverters
Pushes packages across a 800 mm conveyor lane using the 1559 N push force at 0.5 MPa, requiring external guides to prevent rod bending over the long travel.
Pallet Push-Off
Transfers goods between roller lanes where the 3/8 inch port and SC-series mounts allow seamless retrofitting into existing 63 mm bore fixtures.
Replacing the Airtac SU63-100 Standard Cylinder SU63X800SH with the SAU63X800SH
To replace this discontinued SU63X800SH, order the SAU63X800SH direct equivalent, confirming the 63 mm bore, 800 mm stroke, 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware are retained. If moving down, a 50 mm bore yields 982 N push at 0.5 MPa; if moving up, an 80 mm bore provides 2513 N. Because the -S magnet is present, you must upgrade your legacy CS1-B/DS1-B switches to the CMSG/DMSG/EMSG family. The -H Viton seal supports 0-150 C environments. For the 800 mm stroke, always fit external linear guides to manage side loads and prevent rod bending. Finally, this cylinder will not hold a load without live air—the cushions only decelerate—so install an external rod lock or pilot-operated check valve for secure holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X800SH
- ✓ 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 SU63X800SH FAQ
Yes, the AirTAC SU63X800SH is discontinued. The direct replacement is the SAU63X800SH. It matches the 63 mm bore, 800 mm stroke, 1559 N force at 0.5 MPa, 3/8 inch port, and SC-series mounting. You simply order the SAU equivalent.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf maximum at 1.0 MPa. Because this model includes the -S magnet, the legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the SAU replacement.
