This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X400SH, 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 SU63X400SH
The AirTAC SU63-100 Standard Cylinder SU63X400SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 400mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X400SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X400SH
The AirTAC SU63X400SH is a discontinued double-acting profile-type cylinder with a 63 mm bore and 400 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this unit with the SAU63X400SH, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series mounting. This extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.
Because this SKU includes the -S magnet and -H Viton seal, it operated with legacy CS1-B/DS1-B switches at up to 150 C. The SAU successor switches to CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X400SH 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 SAU63X400SH 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 SU63X400SH Is Used
High-Temp Diverting
Actuating diverter gates on hot material conveyors where the Viton H seal survives ambient heat up to 150 C.
Extended Stroke Ejection
Pushing molded parts out of a hot press zone over a 400 mm distance using the 1559 N thrust at 0.5 MPa.
Guided Tooling Shift
Indexing heavy machining fixtures laterally, requiring external guide rails to manage side loads on the long rod.
Replacing the Airtac SU63-100 Standard Cylinder SU63X400SH with the SAU63X400SH
To replace this discontinued SU63X400SH, order the SAU63X400SH direct equivalent, confirming the 63 mm bore, 400 mm stroke, 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware. You must also address the sensor family change: the -S magnet on this legacy unit used CS1-B/DS1-B switches, while the SAU replacement requires CMSG/DMSG/EMSG sensors. The -H seal means you need high-temperature Viton FKM rubber rated for 0 to 150 C. If sizing alternatives, the adjacent 50 mm bore yields 982 N push at 0.5 MPa, and the 80 mm bore yields 2513 N. For the 400 mm stroke, use external guides to prevent rod bending and side-load damage. Remember that a standard cylinder drifts without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve to hold loads safely.
Replacement checklist
- ✓ Same bore / stroke → SAU63X400SH
- ✓ 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 SU63X400SH FAQ
Yes, the SU63X400SH is discontinued. The direct replacement is the SAU63X400SH. It matches the 63 mm bore, 400 mm stroke, 1559 N force, 3/8 inch port, and SC-series mounting. The main change is that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU model.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. The -H seal option uses Viton FKM to raise the operating temperature range from -20 to +70 C up to 0-150 C. Operating pressure is 0.15-1.0 MPa.
