This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X375, 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 SU80X375
The AirTAC Airtac SU63-100 Standard Cylinder SU80X375 is a double-acting profile-type standard cylinder with a Ø80mm bore and 375mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X375, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X375
The AirTAC SU80X375 is a discontinued double-acting profile-type cylinder with an extruded aluminium barrel and adjustable air cushions at both ends. Delivering a push force of 2513 N at 0.5 MPa, this compact unit is shorter than an ISO 15552 cylinder of the same bore and shares AirTAC SC-series mounting accessories.
The direct replacement is the SAU80X375, matching the 80mm bore, 375mm stroke, output force, 3/8" port and mounting footprint. The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X375 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 SAU80X375 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 SU80X375 Is Used
Heavy Clamp Press
Secures large workpieces under fabrication, applying 2513 N of thrust at 0.5 MPa while the adjustable end cushions decelerate the 25mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X375 with the SAU80X375
To replace this discontinued SU80X375, order the SAU80X375 direct equivalent, verifying the 80mm bore, 375mm stroke, 3/8" port, M20x1.5 rod thread and SC-series mounting. If sizing neighbours, the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N. Because this SKU lacks a magnet (-S), it cannot accept a sensor; the SAU family uses CMSG/DMSG/EMSG switches. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. Finally, the 375mm stroke demands external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X375
- ✓ 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 SU80X375 FAQ
Yes, the AirTAC SU80X375 is discontinued and end-of-life. The direct replacement is the SAU80X375. It provides identical 80mm bore, 375mm stroke, output force, 3/8" port, and SC-series mounting compatibility, fitting the exact 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 has no magnet (-S) and cannot take a sensor; if sensing is required, the SAU replacement uses CMSG/DMSG/EMSG switches.
