This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X380, 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 SU63X380
The AirTAC SU63-100 Standard Cylinder SU63X380 is a double-acting profile-type standard cylinder with a Ø63mm bore and 380mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X380, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X380
The AirTAC SU63X380 is a discontinued double-acting profile-type cylinder with a 63mm bore and 380mm stroke. Delivering 1559N push force at 0.5MPa, it is replaced by the direct replacement SAU63X380, which preserves the exact body dimensions, 3/8" port, M16x1.5 rod thread and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade introduces CMSG/DMSG/EMSG switches for -S variants and a SAUF built-in-valve option. Note that air cushions only decelerate; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X380 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 SAU63X380 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 SU63X380 Is Used
Package Diverting
Handles 380mm strokes to push heavy cartons between conveyor lanes, utilizing the 1559N push force at 0.5MPa to reliably shift loads without stalling.
Pallet Stopper Gate
Acts as a robust pneumatic stop for pallets on roller conveyors, where the 63mm bore provides enough thrust to halt momentum while external guides absorb side impacts.
Component Ejection
Ejects machined parts from a fixture over a 380mm distance, requiring external load guidance to prevent rod bending during the extended ejection cycle.
Replacing the Airtac SU63-100 Standard Cylinder SU63X380 with the SAU63X380
To replace this discontinued SU63X380, order the SAU63X380, confirming the 3/8" port, PT thread, and SC-series mounting. Since this is a non-magnet SKU, it cannot support sensing; if needed, specify an SAU -S model and upgrade to CMSG/DMSG/EMSG switches. For the 380mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss, so add a pilot-operated check valve or rod lock to hold loads. If downsizing, a 50mm bore yields 982N push at 0.5MPa; upsizing to 80mm provides 2513N. The SAUF variant integrates a 4M valve if pneumatics need simplifying.
Replacement checklist
- ✓ Same bore / stroke → SAU63X380
- ✓ 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 SU63X380 FAQ
Yes, the SU63X380 is discontinued. The direct replacement is the AirTAC SAU63X380, which matches the 63mm bore, 380mm stroke, 3/8" port, force output, and SC-series mounting accessories.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf max at 1.0MPa. This specific SKU has no magnet, so it cannot take a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
