This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X50STC, 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 SU63X50STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X50STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X50STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X50STC
The AirTAC SU63X50STC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 50 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this end-of-line unit with the SAU63X50STC, a direct alternative retaining the exact profile body, output, and SC-series TC mounting interface.
The SAU body is more compact than an ISO 15552 cylinder of the same bore. Note the sensor family change: this SU -S magnet used legacy CS1-B/DS1-B switches, while the SAU takes current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF built-in valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X50STC 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 SAU63X50STC 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 SU63X50STC Is Used
Package Diverting
Short 50 mm stroke pushes diverter arms on a 3/8 inch air line to route medium-weight parcels reliably.
Clamping Jigs
Supplies 1559 N at 0.5 MPa to secure aluminum extrusions during machining operations.
Replacing the Airtac SU63-100 Standard Cylinder SU63X50STC with the SAU63X50STC
To replace this discontinued SU63X50STC, order the SAU63X50STC. Verify your 3/8 inch port, M16x1.5 rod thread, and TC mounting accessory are retained. If downsizing, a 50 mm bore gives 982 N push at 0.5 MPa; if upsizing, an 80 mm bore yields 2513 N. Because the 50 mm stroke is short, rod bending is minimal, but plain cylinders do not hold load without live air—the cushion only decelerates. Use an external rod lock or pilot-operated check valve for suspended loads. Finally, migrate your -S magnet sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG, and consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X50STC
- ✓ 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 SU63X50STC FAQ
Yes, the SU63X50STC is discontinued. The direct replacement is the SAU63X50STC, which matches the 63 mm bore, 50 mm stroke, 3/8 inch port, force, and TC mounting. You must only swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAU.
This double-acting cylinder has a 3/8 inch port. It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa.
