This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X40S, 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 SU63X40S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X40S is a double-acting profile-type standard cylinder with a Ø63mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X40S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X40S
The AirTAC SU63X40S is a discontinued double-acting profile cylinder with a 63 mm bore and 40 mm stroke. Delivering 1559 N push force at 0.5 MPa via a 3/8" port, it is replaced direct by the SAU63X40S. This upgrade retains the exact extruded body dimensions, M16x1.5 rod, and SC-series mounting. The compact profile body is notably shorter than an ISO 15552 unit of the same bore.
Because the -S suffix denotes a magnet for legacy CS1-B/DS1-B switches, upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF valve-integrated variant, an option the original SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X40S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X40S 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 SU63X40S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×40 | 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 SU63X40S Is Used
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure heavy workpieces during machining operations.
Package Diverting
Short 40 mm stroke quickly pushes cartons off a main belt line into secondary sorting chutes.
Pallet Stops
Acts as a robust pneumatic stop gate for heavy pallets entering a robotic stretch-wrap cell.
Replacing the Airtac SU63-100 Standard Cylinder SU63X40S with the SAU63X40S
To replace this SU63X40S, order the SAU63X40S direct equivalent, confirming the 63 mm bore, 40 mm stroke, 3/8" port, and PT thread. The SC-series mounting accessories transfer over directly. If your build relied on the -S magnet, note that legacy CS1-B/DS1-B switches are obsolete; you must migrate to CMSG/DMSG/EMSG sensors for the SAU. Downsize to a 50 mm bore if you only need 982 N push at 0.5 MPa, or upsize to 80 mm for 2513 N. A plain cylinder drifts without live air, so use an external rod lock or pilot-operated check valve for held loads. The 40 mm stroke is short enough to avoid rod-bending side-load issues.
Replacement checklist
- ✓ Same bore / stroke → SAU63X40S
- ✓ 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 SU63X40S FAQ
Yes, the SU63X40S is discontinued. The direct replacement is the AirTAC SAU63X40S. It shares the identical 63 mm bore, 40 mm stroke, 3/8" port, output force, and SC-series mounting hardware, so it fits the same application without mechanical modifications.
The cylinder delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because your SU63X40S uses a magnet (-S) for legacy CS1-B/DS1-B switches, the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
