This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X70S, 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 SU80X70S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X70S is a double-acting profile-type standard cylinder with a Ø80mm bore and 70mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X70S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X70S
The AirTAC SU80X70S is a discontinued double-acting profile-type cylinder with an 80mm bore and 70mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, operating via a 3/8 port with a 25mm rod. AirTAC replaced this unit with the SAU80X70S, a direct upgrade sharing the exact bore, stroke, output force, port size, and SC-series mounting footprint.
The SAU replacement upgrades your legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches, and introduces the SAUF built-in 4M solenoid valve option the SU line lacked. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X70S 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 SAU80X70S 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 SU80X70S Is Used
Heavy Press Ejection
Provides robust push force to eject dense stamped metal parts from a hydraulic press bed, utilizing the 70mm stroke for rapid, short-cycle clearing.
Pallet Diverting
Actuates heavy-duty lane diverters on high-throughput packaging lines, easily handling the side-load of shifting loaded pallets at 30-800 mm/s.
Replacing the Airtac SU63-100 Standard Cylinder SU80X70S with the SAU80X70S
To replace this SU80X70S, order the SAU80X70S. Confirm your 80mm bore, 70mm stroke, 3/8 port, and M20x1.5 rod thread. Because this SKU has the -S magnet, your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new cylinder. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore provides 3927N. A plain cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant can simplify cycling if you lack a separate valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X70S
- ✓ 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 SU80X70S FAQ
Yes, the SU80X70S is discontinued. The direct replacement is the AirTAC SAU80X70S. It matches the 80mm bore, 70mm stroke, 2513N force at 0.5MPa, 3/8 port, and SC-series mounting, but requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
The 3/8 port feeds a 25mm rod delivering 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a theoretical max of 513 kgf at 1.0MPa. The cylinder lacks a load-holding brake; the 28mm adjustable cushion only decelerates the piston near stroke end.
