This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X25CA, 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 SU80X25CA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X25CA is a double-acting profile-type standard cylinder with a Ø80mm bore and 25mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X25CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X25CA
The AirTAC SU80X25CA is a discontinued double-acting profile-type cylinder with an 80 mm bore and 25 mm stroke. It delivers 2513 N push and 2268 N pull force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU80X25CA, a direct replacement retaining the exact bore, stroke, output force, port size and SC-series CA mounting accessory.
Because of its short 25 mm stroke, this unit is highly compact, featuring an extruded aluminum barrel shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet and cannot accept sensors; furthermore, the cushion only decelerates the piston and will not hold a load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X25CA 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 SAU80X25CA 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 SU80X25CA Is Used
Heavy-Duty Clamping
Ideal for securing heavy castings during machining, using the 2513 N push force at 0.5 MPa to hold parts rigidly within a very short 25 mm stroke.
Press Fit Operations
Provides reliable downward thrust for assembling bushings or pins into housings, where high force over a compact displacement is required.
Short-Stroke Ejection
Suits stamping line ejectors that need to quickly push heavy parts out of a die using a brief, powerful 25 mm movement.
Replacing the Airtac SU63-100 Standard Cylinder SU80X25CA with the SAU80X25CA
To replace this discontinued SU80X25CA, order the SAU80X25CA, verifying the 80 mm bore, 25 mm stroke, 3/8" port, M20x1.5 rod thread, and CA mounting. Since this SKU has no -S magnet, it cannot accept position sensors; if sensing is needed, the SAU upgrade requires current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B family. For sizing, the 80 mm bore yields 2513 N push at 0.5 MPa; if less force is acceptable, a 63 mm bore provides 1559 N. A plain cylinder drifts on air loss, so for vertical or held loads install an external rod lock or pilot-operated check valve. The SAU family also offers the SAUF variant with a built-in 4M solenoid valve, an option the SU line never had.
Replacement checklist
- ✓ Same bore / stroke → SAU80X25CA
- ✓ 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 SU80X25CA FAQ
Yes, the SU80X25CA is discontinued. The direct replacement is the AirTAC SAU80X25CA. It features the same 80 mm bore, 25 mm stroke, 2513 N push force at 0.5 MPa, 3/8" port, and CA mounting, so it drops directly into the same application.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept sensors. If sensing is required, the SAU replacement uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B.
