This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X375, 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 SU63X375
The AirTAC Airtac SU63-100 Standard Cylinder SU63X375 is a double-acting profile-type standard cylinder with a Ø63mm bore and 375mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X375, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X375
The AirTAC SU63X375 is a discontinued double-acting profile-type cylinder with a 63mm bore and 375mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this EOL unit with the SAU63X375, a direct upgrade retaining the exact body, stroke, force, and SC-series mounting.
The SAU upgrade adds a built-in 4M solenoid valve option (SAUF) the SU lacked. This specific SKU has no magnet (-S) and cannot accept a sensor; if you previously used an -S model, note the SAU uses CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X375 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 SAU63X375 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 SU63X375 Is Used
Pallet Diversion
Pushes heavy pallets onto auxiliary transfer lines using 1559N of thrust at 0.5MPa, with the 375mm stroke clearing wide conveyor frames.
Component Ejection
Ejects dense machined parts from a fixture, using adjustable end cushions to decelerate the 20mm rod smoothly over the 375mm travel.
Replacing the Airtac SU63-100 Standard Cylinder SU63X375 with the SAU63X375
To replace this discontinued SU63X375, order the SAU63X375 direct: verify the 3/8" port, M16x1.5 rod thread, PT/G/NPT thread standard, and your SC-series mounts (LB/FA/FB/CA/CB). This SKU lacks a magnet, so it cannot take a sensor; if you need position detection, specify an SAU63X375-S and migrate to CMSG/DMSG/EMSG switches. Bore 63 provides 1559N push at 0.5MPa; if undersized, step up to bore 80 (2513N). For the 375mm stroke, use an external guide to prevent rod bending and side-load wear. The cylinder will not hold a load on air loss—use an external rod lock or pilot-operated check valve. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X375
- ✓ 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 SU63X375 FAQ
Yes, the AirTAC SU63X375 is discontinued and end-of-life. The direct replacement is the SAU63X375. It shares the same 63mm bore, 375mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it drops directly into the same application.
At 0.5MPa it provides 1559N push and 1402N pull; at 0.7MPa it pushes 2182N; at 0.9MPa it pushes 2805N; and the theoretical max is 318kgf at 1.0MPa. This specific SKU has no magnet (-S) and cannot accept a sensor. If sensing is required, order the SAU63X375-S replacement, which uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
