This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X500STC, 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 SU63X500STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X500STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X500STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X500STC
The AirTAC SU63X500STC is a discontinued double-acting profile-type cylinder with a 63mm bore and 500mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. AirTAC replaced this EOL unit with the SAU63X500STC, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
When upgrading, note the SAU uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, and the SAUF variant adds a built-in valve the SU lacked. The 500mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X500STC 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 SAU63X500STC 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 SU63X500STC Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using the 1559N thrust at 0.5MPa, with TC mounting allowing rigid centerline support.
Vertical Lift Gate
Raises a 79kg materials gate through the 500mm stroke, requiring external linear guides to prevent rod bending on the 63mm bore body.
Press Ejection
Ejects formed metal parts from a press bed, relying on adjustable 21mm air cushions to decelerate the payload smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU63X500STC with the SAU63X500STC
To replace the SU63X500STC, order the SAU63X500STC. Confirm the 3/8" port, M16x1.5 rod thread, and TC mounting accessory are retained. If moving down to a 50mm bore, expect only 982N push at 0.5MPa; stepping up to an 80mm bore yields 2513N. Because the stroke is 500mm, use external guides to prevent rod bending. This TC-mounted cylinder does not hold loads without live air; use a pilot-operated check valve or rod lock for safety. The SAU's -S magnet switches to CMSG/DMSG/EMSG sensors, and the SAUF offers an integrated valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X500STC
- ✓ 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 SU63X500STC FAQ
Yes, the SU63X500STC is discontinued. The direct replacement is the SAU63X500STC, which shares the same 63mm bore, 500mm stroke, 3/8" port, output force, and TC mounting.
It provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
