This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X700SLB, 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 SU63X700SLB
The AirTAC Airtac SU63-100 Standard Cylinder SU63X700SLB 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 SAU63X700SLB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X700SLB
The AirTAC SU63X700SLB is a discontinued double-acting profile cylinder with a 63mm bore and 700mm stroke. Delivering 1559N push at 0.5MPa via a 3/8" port, it is replaced directly by the SAU63X700SLB. This direct successor matches the exact body, force, and LB mounting footprint.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X700SLB 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 SAU63X700SLB 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 SU63X700SLB Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across a 700mm transfer gap using the 1559N thrust at 0.5MPa.
Multi-Stage Ejection
Extends 700mm to clear large machined castings from a fixture before the next cycle begins.
Replacing the Airtac SU63-100 Standard Cylinder SU63X700SLB with the SAU63X700SLB
To replace this SU63X700SLB, order the SAU63X700SLB keeping the 63mm bore, 700mm stroke, 3/8" port, and LB mounting. If sizing alternatives, the adjacent 50mm bore yields 982N push while the 80mm provides 2513N at 0.5MPa. For the -S magnet, note the SAU requires CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B. At 700mm stroke, prevent rod bending by supporting the load with external guides. A plain cylinder drifts on air loss; the cushions only decelerate. For load holding, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X700SLB
- ✓ 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 SU63X700SLB FAQ
Yes, the SU63X700SLB is discontinued. The direct replacement is the SAU63X700SLB. It matches the 63mm bore, 700mm stroke, 1559N force, 3/8" port, and LB mounting. You must upgrade your sensors: the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 3/8" port bore delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa with adjustable 21mm cushions at both ends.
