This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X370S, 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 SU80X370S
The AirTAC SU63-100 Standard Cylinder SU80X370S is a double-acting profile-type standard cylinder with a Ø80mm bore and 370mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X370S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X370S
The AirTAC SU80X370S is a discontinued double-acting profile-type cylinder with an 80 mm bore and 370 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this unit with the SAU80X370S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
Because the 370 mm stroke is long, use an external guide to prevent rod bending under side loads. The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches on this -S model, and offers a new SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X370S 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 SAU80X370S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X370S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×370 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU80X370S Is Used
Pallet Diversion
Pushes heavy pallets off a main conveyor line using the 2513 N push force at 0.5 MPa, with the 370 mm stroke clearing the belt width.
Material Press
Holds composite sheets in a curing press, utilizing the 28 mm adjustable air cushions at both ends to decelerate the heavy 80 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X370S with the SAU80X370S
To replace this discontinued SU80X370S, order the SAU80X370S. Confirm your 3/8 inch port, M20x1.5 rod thread, and SC-series mounting. If moving down to a 63 mm bore, the push force drops to 1559 N at 0.5 MPa; moving up to 100 mm yields 3927 N. The -S magnet means a sensor family change: your old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. For the 370 mm stroke, add external guides to absorb side loads and prevent rod bending. A plain cylinder drifts without air; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X370S
- ✓ 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 SU80X370S FAQ
Yes, the SU80X370S is discontinued. The direct replacement is the SAU80X370S. It shares the same 80 mm bore, 370 mm stroke, 2513 N force, 3/8 inch port, and SC-series mounting. The SAU also adds an optional SAUF built-in valve variant the SU lacked.
The SAU80X370S matches the SU forces: 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf max at 1.0 MPa. Because your old model has an -S magnet, the legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors on the SAU.
