This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X300TC, 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 SU80X300TC
The AirTAC SU63-100 Standard Cylinder SU80X300TC is a double-acting profile-type standard cylinder with a Ø80mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X300TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X300TC
The AirTAC SU80X300TC is a discontinued double-acting profile-type cylinder with an 80 mm bore and 300 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at a 513 kgf theoretical maximum. The direct replacement is the SAU80X300TC, preserving the 3/8" port, M20x1.5 rod thread, and TC mounting interface.
The SAU upgrade adopts CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option the SU lacked. This no-magnet SKU cannot accept a switch, and the extruded aluminium body remains more compact than an ISO 15552 equivalent.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X300TC 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 SAU80X300TC 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 SU80X300TC Is Used
Pallet Diversion
Routes heavy pallets on a packaging line using the 2513 N push force at 0.5 MPa, while the TC mount handles the pivot requirements.
Press Ejection
Pushes finished parts out of a light press, relying on the 28 mm adjustable air cushions to decelerate the 25 mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X300TC with the SAU80X300TC
To replace the SU80X300TC, order the SAU80X300TC direct equivalent, verifying the 80 mm bore, 300 mm stroke, 3/8" port, and TC mounting accessory from the SC-series. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore provides 3927 N. Because this is a no-magnet SKU, it cannot support a magnetic sensor. At 300 mm stroke, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU80X300TC
- ✓ 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 SU80X300TC FAQ
Yes, the AirTAC SU80X300TC is discontinued and end-of-life. The direct replacement is the SAU80X300TC. It shares the identical 80 mm bore, 300 mm stroke, 3/8" port, output force, and SC-series TC mounting, so it fits the same application directly.
At 0.5 MPa it provides 2513 N push and 2268 N pull, rising to 3518 N at 0.7 MPa, with a 513 kgf maximum at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor. The older SU-S variants used CS1-B/DS1-B switches, while the SAU replacement uses CMSG/DMSG/EMSG sensors.
