This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X215S, 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 SU63X215S
The AirTAC SU63-100 Standard Cylinder SU63X215S is a double-acting profile-type standard cylinder with a Ø63mm bore and 215mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X215S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X215S
The AirTAC SU63X215S is a discontinued double-acting profile-type cylinder with a 63 mm bore and a 215 mm non-standard stroke. It delivers 1559 N of push force at 0.5 MPa (318 kgf maximum at 1.0 MPa) and uses a 3/8" port with an M16x1.5 rod thread. AirTAC replaced this legacy unit with the SAU63X215S, a direct replacement retaining the exact same profile body, stroke, output force, port size, and SC-series mounting.
Because the 215 mm stroke is non-standard, verify lead times when ordering the SAU equivalent. Note that the SU-S magnet functioned with legacy CS1-B/DS1-B switches, whereas the SAU replacement utilizes the current CMSG/DMSG/EMSG sensor family. Furthermore, the SAU line introduces a SAUF variant featuring a built-in 4M solenoid valve, an integrated self-switching option the SU series never offered.

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 SAU63X215S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU63X215S Is Used
Mid-Tonnage Part Clamping
Ideal for securing heavy machined components during milling or drilling, utilizing the 1559 N push force at 0.5 MPa to hold parts firmly against fixture stops.
Package Diverting
Drives diverter arms on packaging lines to route heavy cartons, with the 215 mm stroke providing the exact reach needed to clear adjacent conveyor lanes.
Pallet Lift Gates
Actuates safety gates or low-rise lift stops at palletizing stations, where the non-standard 215 mm stroke matches specific machinery guard clearances.
Replacing the Airtac SU63-100 Standard Cylinder SU63X215S with the SAU63X215S
To replace the discontinued SU63X215S, order the SAU63X215S and confirm the 63 mm bore, 215 mm non-standard stroke, 3/8" port, and M16x1.5 rod thread. Specify the thread standard (PT, G, or NPT) and your SC-series mounting accessories (LB, FA, FB, CA, CB, TC, or TCM1). Because this SKU includes the -S magnet, you must upgrade your sensors: the old CS1-B/DS1-B switches will not fit the SAU, so select current CMSG, DMSG, or EMSG reed switches. If your application requires integrated flow control, explore the SAUF variant which adds a built-in 4M solenoid valve. For sizing alternatives, dropping to a 50 mm bore reduces push force to 982 N at 0.5 MPa, while stepping up to an 80 mm bore increases it to 2513 N. Finally, since 215 mm exceeds standard increments, ensure your guidance handles any side-load to prevent rod bending, and remember that a plain cylinder drifts on air loss—use an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X215S
- ✓ 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 SU63X215S FAQ
Yes, the AirTAC SU63X215S is discontinued and end-of-life. The direct replacement is the SAU63X215S. It shares the identical 63 mm bore, 215 mm stroke, 318 kgf maximum force, 3/8" port, and SC-series mounting, so it fits the same application without mechanical modifications.
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf maximum at 1.0 MPa. Because this SU model has the -S magnet, it originally used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to the current CMSG, DMSG, or EMSG sensor family.
