This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X250SH, 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 SU63X250SH
The AirTAC SU63-100 Standard Cylinder SU63X250SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X250SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X250SH
The AirTAC SU63X250SH is a discontinued double-acting profile cylinder with a 63 mm bore and 250 mm stroke. It delivers 1559 N push force at 0.5 MPa. AirTAC replaced it with the SAU63X250SH, a direct upgrade retaining the exact bore, stroke, force, 3/8" port, and SC-series mounting.
This legacy SU features a piston magnet for CS1-B/DS1-B switches; the SAU replacement transitions to CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF valve-integrated variant. The H seal allows 0-150 C high-temp operation.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X250SH 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 SAU63X250SH 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 SU63X250SH Is Used
Hot Stamp Ejection
Uses the 1559 N push force and Viton H high-temp seals to eject stamped parts from 150 C press beds without seal degradation.
Heated Product Diversion
Diverts warm packaged goods along a 250 mm stroke, safely handling the ~79 kg vertical-lift margin while matching existing SC mounts.
Pallet Stop Gate
Acts as a high-force 63 mm bore stop gate for pallets, dropping in seamlessly via SC-series accessories where the old SU was installed.
Replacing the Airtac SU63-100 Standard Cylinder SU63X250SH with the SAU63X250SH
To replace the SU63X250SH, order the SAU63X250SH, matching the 63 mm bore, 250 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU has the S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The H designation specifies Viton seals for 0-150 C environments. If sizing alternatives, the 80 mm bore yields 2513 N push at 0.5 MPa, while the 50 mm bore yields 982 N. A plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock for held loads. At 250 mm stroke, ensure guide alignment to prevent rod bending. The SAUF offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X250SH
- ✓ 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 SU63X250SH FAQ
Yes, the AirTAC SU63X250SH is discontinued. The direct replacement is the SAU63X250SH. It matches the 63 mm bore, 250 mm stroke, 1559 N force, 3/8" port, and SC-series mounting. You simply order the SAU equivalent.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf max at 1.0 MPa. The built-in magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
