This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1650S, 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 SU80X1650S
The AirTAC SU63-100 Standard Cylinder SU80X1650S is a double-acting profile-type standard cylinder with a Ø80mm bore and 1650mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1650S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1650S
The AirTAC SU80X1650S is a discontinued double-acting profile-type cylinder with an 80mm bore and a 1650mm stroke. Because 1650mm exceeds the 1500mm maximum standard stroke for this bore, it is a non-standard, made-to-order length. It delivers 2513 N of push force at 0.5 MPa. AirTAC replaced the SU line with the SAU family; the SAU80X1650S is the direct replacement, matching the body, bore, stroke, force, 3/8" port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this SU -S model. The SAU line also adds a SAUF variant with a built-in 4M solenoid valve. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1650S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X1650S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×1650 | 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 SU80X1650S Is Used
Long-Reach Transfer
Pushes heavy pallets along a 1.6m conveyor line using the 2513 N push force at 0.5 MPa, requiring external guides to support the extended rod.
Large Press Feed
Feeds heavy sheet metal into a press over a long distance, relying on adjustable 28mm cushions to decelerate the payload smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1650S with the SAU80X1650S
To replace this discontinued SU80X1650S, order the SAU80X1650S direct. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) stay the same. The -S magnet means you must upgrade from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. At 0.5 MPa, push is 2513 N and pull is 2268 N; if undersizing, a 63mm bore yields 1559 N push. Because the 1650mm stroke exceeds the 1500mm standard max, expect a made-to-order unit. At this length, prevent rod bending by guiding the load externally. The air cushion only decelerates near stroke end; add a pilot-operated check valve to hold loads. The SAUF valve-integrated option can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1650S
- ✓ 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 SU80X1650S FAQ
Yes, the SU80X1650S is discontinued. The direct replacement is the SAU80X1650S. It matches the 80mm bore, 1650mm stroke, 2513 N force, 3/8" port, and SC-series mounting. The only change is that your legacy CS1-B/DS1-B sensors must be upgraded to CMSG/DMSG/EMSG switches.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa push is 3518 N; the theoretical max is 513 kgf at 1.0 MPa. The 1650mm stroke is non-standard (max standard is 1500mm). The 3/8" port cylinder runs 30-800 mm/s. It does not hold load without live air; use an external rod lock.
