This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X300S, 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 SU80X300S
The AirTAC SU63-100 Standard Cylinder SU80X300S 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 SAU80X300S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X300S
The AirTAC SU80X300S is a discontinued double-acting profile cylinder with an 80mm bore and 300mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, utilizing a 25mm rod and 3/8" port. AirTAC replaced this legacy unit with the SAU80X300S, a direct alternative sharing the exact bore, stroke, force, port size, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and offers a new SAUF valve-integrated variant. Note that air cushions only decelerate; an external rod lock is required to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X300S 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 SAU80X300S 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 SU80X300S Is Used
Press Ejection
Ejects dense manufactured parts from machinery, utilizing the compact profile body and adjustable 28mm cushions to soften end-of-stroke impacts.
Replacing the Airtac SU63-100 Standard Cylinder SU80X300S with the SAU80X300S
To replace the SU80X300S, order the SAU80X300S. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB/TC). Because this SKU includes a magnet (-S), you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If sizing alternatives, neighboring bores (63mm or 100mm) offer 1559N or 3927N push at 0.5MPa respectively. For the 300mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts without air; use a pilot-operated check valve for load holding. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X300S
- ✓ 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 SU80X300S FAQ
Yes, the SU80X300S is discontinued. The direct replacement is the AirTAC SAU80X300S. It matches the 80mm bore, 300mm stroke, 2513N force, 3/8" port, and SC-series mounting accessories. You simply order the SAU equivalent.
The SAU80X300S provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. Because your SU model has a magnet (-S), the legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU cylinder.
