This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X770, 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 SU63X770
The AirTAC Airtac SU63-100 Standard Cylinder SU63X770 is a double-acting profile-type standard cylinder with a Ø63mm bore and 770mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X770, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X770
The AirTAC SU63X770 is a discontinued double-acting profile-type standard cylinder with a 63 mm bore and 770 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X770, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
This compact extruded aluminium body is shorter than an ISO 15552 cylinder of the same bore. Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade also introduces the SAUF built-in 4M solenoid valve variant, which the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X770 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 SAU63X770 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 SU63X770 Is Used
Long-Stroke Diversion
Pushes heavy packages across a 770 mm transfer zone using 1559 N of thrust at 0.5 MPa, requiring external guides to prevent rod bending.
Pallet Push-Off
Uses the 1402 N pull force at 0.5 MPa to retract a 770 mm actuator after ejecting pallets, fitting AirTAC SC-series mounting brackets.
Material Ejection
Ejects moulded parts from a press over a 770 mm distance, relying on the adjustable 21 mm air cushions to decelerate the 20 mm rod safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X770 with the SAU63X770
To replace the SU63X770, order the SAU63X770 direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware (LB/FA/FB/CA/CB). If sizing alternatives, neighbouring bores are 50 mm (982 N push @0.5 MPa) and 80 mm (2513 N push @0.5 MPa). This 770 mm stroke requires an external guide to prevent rod bending and side-load damage. The cylinder will not hold a load without live air—use an external rod lock or pilot-operated check valve, as the adjustable 21 mm cushions only decelerate at stroke ends. The SAU family also adds the SAUF valve-integrated option if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X770
- ✓ 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 SU63X770 FAQ
Yes, the SU63X770 is discontinued. The direct replacement is the AirTAC SAU63X770. It matches the 63 mm bore, 770 mm stroke, 1559 N push force at 0.5 MPa, 3/8" port, and SC-series mounting accessories. 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 specific SKU lacks a magnet (-S), it cannot accept a sensor. If sensing is required, the SAU63X770S replacement uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
