This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X700, 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 SU63X700
The AirTAC Airtac SU63-100 Standard Cylinder SU63X700 is a double-acting profile-type standard cylinder with a Ø63mm bore and 700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X700, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X700
The AirTAC SU63X700 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 700 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X700 direct replacement, retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor. If you previously used an -S variant, note the SAU upgrade transitions from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X700 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 SAU63X700 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 SU63X700 Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways on a 63 mm bore line using the 700 mm stroke, relying on the 1559 N push force at 0.5 MPa to overcome friction.
Heavy Clamping Fixture
Secures large metal castings during machining, using the 2182 N push force at 0.7 MPa to hold the part rigidly against cutting forces.
Replacing the Airtac SU63-100 Standard Cylinder SU63X700 with the SAU63X700
To replace this SU63X700, order the SAU63X700. Confirm your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). This non-magnet SKU cannot take a switch; if sensing is needed, order the SAU63X700S and migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG switches. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. For load holding, add an external rod lock or pilot-operated check valve, as cushions only decelerate. With a 700 mm stroke, use external guides to prevent rod bending under side loads. Consider the SAUF valve-integrated variant for self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X700
- ✓ 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 SU63X700 FAQ
Yes, the AirTAC SU63X700 is discontinued. The direct replacement is the SAU63X700. It shares the same 63 mm bore, 700 mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application directly.
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 theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet (-S) and cannot accept a sensor. If you need sensing, the SAU replacement uses CMSG/DMSG/EMSG switches.
