This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X650SLB, 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 SU63X650SLB
The AirTAC SU63-100 Standard Cylinder SU63X650SLB 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 SAU63X650SLB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X650SLB
The AirTAC SU63X650SLB is a discontinued double-acting profile cylinder with a 63 mm bore and 650 mm stroke. It delivers 1559 N push force at 0.5 MPa and features a 3/8" port with an M16x1.5 rod thread. AirTAC replaced this legacy unit with the SAU63X650SLB, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series LB mounting interface.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the SU's legacy CS1-B/DS1-B switches, and offers a new SAUF built-in valve variant. Remember that a standard cylinder drifts without live air; the cushions only decelerate, so use an external rod lock for load holding. At 650 mm, add external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X650SLB 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 SAU63X650SLB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 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 SU63X650SLB Is Used
Long-Stroke Diverting
Pushes heavy pallets laterally across transfer lines using the 650 mm stroke and 1559 N force, guided externally to prevent rod bending.
Heavy Part Ejection
Clears dense machined components from press beds, utilizing the compact profile body and adjustable 21 mm cushions to soften end-of-stroke impacts.
Replacing the Airtac SU63-100 Standard Cylinder SU63X650SLB with the SAU63X650SLB
To replace this discontinued SU63X650SLB, order the SAU63X650SLB, confirming the 63 mm bore, 650 mm stroke, 3/8" port, and LB mounting are retained. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N. The -S magnet means you must upgrade from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. For the 650 mm stroke, use external guides to prevent rod bending under side loads. This cylinder does not hold load on air loss; install a pilot-operated check valve or rod lock. The SAUF valve-integrated option can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X650SLB
- ✓ 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 SU63X650SLB FAQ
Yes, the AirTAC SU63X650SLB is discontinued. The direct replacement is the SAU63X650SLB. It matches the 63 mm bore, 650 mm stroke, 1559 N force, 3/8" port, and SC-series LB mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. It pushes 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. Because this SU63X650SLB has a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
