This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X380TC, 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 SU63X380TC
The AirTAC SU63-100 Standard Cylinder SU63X380TC 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 SAU63X380TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X380TC
The AirTAC SU63X380TC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 380 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and shares AirTAC SC-series mounting. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a theoretical 318 kgf at 1.0 MPa.
The direct replacement is the SAU63X380TC, matching the 3/8" port, M16x1.5 rod thread, and TC mounting. Note this SKU lacks a magnet, so it cannot accept a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches for -S variants and adds a SAUF valve-integrated option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X380TC 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 SAU63X380TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×380 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X380TC Is Used
Pallet Handling
Extends a TC-mounted stop gate in pallet flow systems, leveraging the 1559 N push force at 0.5 MPa to halt heavy goods.
Component Ejection
Ejects machined parts from a CNC enclosure over a 380 mm distance, relying on adjustable end cushions to decelerate the 20 mm rod.
Replacing the Airtac SU63-100 Standard Cylinder SU63X380TC with the SAU63X380TC
To replace this discontinued SU63X380TC, order the SAU63X380TC. Verify the 63 mm bore, 380 mm stroke, 3/8" port, M16x1.5 rod thread, and TC mounting accessory. Because this SKU has no -S magnet, it cannot take a sensor; if sensing is needed, order the SAU63X380TC-S and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing both ways: a 50 mm bore gives 982 N push @0.5 MPa, while an 80 mm bore yields 2513 N. For the 380 mm stroke, use an external guide to prevent rod bending and side-load wear. The air cushion only decelerates; for load holding on air loss, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X380TC
- ✓ 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 SU63X380TC FAQ
Yes, the SU63X380TC is discontinued. The direct replacement is the SAU63X380TC. It provides the same 63 mm bore, 380 mm stroke, 3/8" port, TC mounting, and output force. The SAU body is fully compatible with existing AirTAC SC-series accessories.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept a sensor. If sensing is required, the SAU63X380TC-S replacement uses CMSG/DMSG/EMSG switches.
