This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X400FA, 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 SU63X400FA
The AirTAC Airtac SU63-100 Standard Cylinder SU63X400FA is a double-acting profile-type standard cylinder with a Ø63mm bore and 400mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X400FA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X400FA
The AirTAC SU63X400FA is a discontinued double-acting profile-type cylinder with a 63 mm bore and 400 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, scaling to 2805 N at 0.9 MPa (theoretical max 318 kgf). The direct replacement is the SAU63X400FA, matching the 3/8" port, M16x1.5 rod thread, and FA mounting interface.
This extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore, reusing AirTAC SC-series accessories. Because this SKU lacks a magnet, it cannot accept a sensor. Note the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X400FA 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 SAU63X400FA 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 SU63X400FA Is Used
Pallet Diversion
Pushes heavy pallets onto secondary packaging lines using the 1559 N @0.5 MPa thrust, guided externally to handle the 400 mm stroke.
Component Ejection
Ejects formed metal parts from hydraulic presses, relying on the adjustable 21 mm air cushions to decelerate the rod at stroke ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X400FA with the SAU63X400FA
To replace this SU63X400FA, order the SAU63X400FA, confirming the 63 mm bore, 400 mm stroke, 3/8" port, and SC-series FA mount. The SAU body, force, and cushioning (21 mm adjustable) are identical. If sizing neighbors, a 50 mm bore yields 982 N push @0.5 MPa, while an 80 mm bore yields 2513 N. Since this is a 400 mm stroke, use an external guide to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. This no-magnet SKU cannot take a switch.
Replacement checklist
- ✓ Same bore / stroke → SAU63X400FA
- ✓ 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 SU63X400FA FAQ
Yes, the SU63X400FA is discontinued. The direct replacement is the SAU63X400FA, offering the same 63 mm bore, 400 mm stroke, 3/8" port, FA mount, and output force. The SAU also introduces a SAUF variant with a built-in 4M solenoid valve.
It delivers 1559 N push and 1402 N pull @0.5 MPa, 2182 N @0.7 MPa, 2805 N @0.9 MPa, and a 318 kgf max @1.0 MPa. This specific SKU has no magnet and cannot accept a sensor. If sensing is needed, the SAU replacement supports CMSG/DMSG/EMSG switches.
