This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X650S, 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 SU63X650S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X650S 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 SAU63X650S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X650S
The AirTAC SU63X650S is a discontinued double-acting profile-type cylinder with a 63mm bore and 650mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa. The direct replacement is the SAU63X650S, which preserves the exact bore, stroke, output force, 3/8" port, and SC-series mounting. You can install the SAU without modifying the machine.
The extruded aluminium profile is more compact than an ISO 15552 cylinder of the same bore. Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU successor requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X650S 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 SAU63X650S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU63X650S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×650 | 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 SU63X650S Is Used
Long-Stroke Ejection
Ejects formed parts from deep machinery beds, requiring external guide rails to prevent rod bending over 650mm.
Replacing the Airtac SU63-100 Standard Cylinder SU63X650S with the SAU63X650S
To replace this discontinued SU63X650S, order the SAU63X650S. Confirm the 3/8" port, M16x1.5 rod thread, and PT/G/NPT thread preference. The SC-series mounting accessories (LB/FA/FB/CA/CB) transfer directly. Because this has a 650mm stroke, use an external guide to prevent rod bending and side-load damage. If moving down to a 50mm bore yields insufficient force (982N push at 0.5MPa), keep the 63mm bore; stepping up to 80mm gives 2513N. The -S magnet means you must switch from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. A plain cylinder drifts without live air, so fit an external rod lock for held loads. Consider the SAUF for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU63X650S
- ✓ 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 SU63X650S FAQ
Yes, the SU63X650S is discontinued. The direct replacement is the SAU63X650S. It matches the 63mm bore, 650mm stroke, 3/8" port, output force, and SC-series mounting, so no mechanical changes are needed.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. The -S suffix means it has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors instead.
