This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X650, 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 SU63X650
The AirTAC Airtac SU63-100 Standard Cylinder SU63X650 is a double-acting profile-type standard cylinder with a Ø63mm bore and 650mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X650, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X650
The AirTAC SU63X650 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 650 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, with a 3/8" port. AirTAC replaced this EOL unit with the SAU63X650, a direct replacement retaining the exact bore, stroke, force, port and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option the SU lacked. This non-magnet SKU cannot take a switch. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X650 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 SAU63X650 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 SU63X650 Is Used
Pallet Diversion
Uses the 1559 N push at 0.5 MPa to deflect heavy pallets on a packaging line, while the 650 mm stroke provides full lane clearance.
Long-Stroke Ejection
Pushes machined parts out of a workstation using the 650 mm extension, requiring external guides to prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU63X650 with the SAU63X650
To replace this discontinued SU63X650, order the SAU63X650. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mount (LB/FA/FB/CA/CB). This SKU lacks a magnet, so no sensor fits; if you need position detection, specify an SAU -S model and migrate to CMSG/DMSG/EMSG switches. If dropping to a 50 mm bore yields 982 N push, but a 63 mm bore is safer for drift. At 650 mm stroke, prevent rod bending with an external guide. A plain cylinder drifts on air loss; use a rod lock or pilot check valve to hold loads. The SAUF valve-integrated variant can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X650
- ✓ 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 SU63X650 FAQ
Yes, the SU63X650 is discontinued. The direct replacement is the AirTAC SAU63X650. It matches the 63 mm bore, 650 mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application without mechanical changes.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet (-S), so it cannot accept a sensor. If sensing is needed, an SAU -S variant uses CMSG/DMSG/EMSG switches.
