This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X310S, 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 SU63X310S
The AirTAC SU63-100 Standard Cylinder SU63X310S is a double-acting profile-type standard cylinder with a Ø63mm bore and 310mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X310S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X310S
The AirTAC SU63X310S is a discontinued double-acting profile-type cylinder with a 63mm bore and 310mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, operating at 30-800mm/s through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X310S, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
The extruded aluminum profile is more compact than a same-bore ISO 15552 unit. Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU successor upgrades 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 SAU63X310S 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 SAU63X310S 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 SU63X310S Is Used
Pallet Stops
Halts inbound pallets using the 1402N pull force, relying on the adjustable 21mm cushions to soften end-of-stroke impacts.
Clamp Actuation
Secures workpieces during machining, providing up to 318kgf theoretical clamping at 1.0MPa within a compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X310S with the SAU63X310S
To replace this SU63X310S, order the SAU63X310S, confirming the 63mm bore, 310mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). If sizing alternatives, dropping to a 50mm bore reduces push to 982N at 0.5MPa, while an 80mm bore increases it to 2513N. The 310mm stroke requires external guides to prevent rod bending under side loads. Note the -S magnet switches from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. Air cushions only decelerate the piston; they do not hold loads, so add an external rod lock or pilot-operated check valve for fail-safe holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X310S
- ✓ 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 SU63X310S FAQ
Yes, the SU63X310S is discontinued. The direct replacement is the AirTAC SAU63X310S. It shares the same 63mm bore, 310mm stroke, 1559N output force at 0.5MPa, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
The 63mm bore provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf theoretical max at 1.0MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
