This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X185, 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 SU63X185
The AirTAC SU63-100 Standard Cylinder SU63X185 is a double-acting profile-type standard cylinder with a Ø63mm bore and 185mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X185, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X185
The AirTAC SU63X185 is a discontinued double-acting profile-type cylinder with a 63mm bore and 185mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, making it a robust choice for medium-force tasks. AirTAC replaced this end-of-line unit with the SAU63X185, a direct alternative retaining the exact body, 3/8" port, M16x1.5 rod thread, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches, and adds a SAUF built-in 4M valve option the SU line lacked. Note this non-magnet SKU cannot accept a sensor, and the cushion only decelerates; use a rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X185 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 SAU63X185 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 SU63X185 Is Used
Package Diversion
Drives a medium-duty diverter arm on a packaging line, utilizing the 1559N push force at 0.5MPa to reliably redirect heavy cartons without hesitation.
Clamp Actuation
Secures workpieces during machining operations, providing consistent 1402N pull force at 0.5MPa while the compact profile body saves valuable fixture space.
Replacing the Airtac SU63-100 Standard Cylinder SU63X185 with the SAU63X185
To replace the SU63X185, order the SAU63X185, confirming the 3/8" port, PT/G/NPT thread, and SC-series mounts (LB/FA/FB/CA/CB). Because this 185mm stroke is under the 300mm threshold, side-load rod bending is less critical, but always guide the load. Size both ways: drop to a 50mm bore for 982N push, or step up to an 80mm bore for 2513N. This non-magnet version cannot take a sensor; if detection is needed, specify an -S SAU model and migrate to CMSG/DMSG/EMSG switches. The cushion only decelerates; for load holding on air loss, add an external pilot-operated check valve or rod lock. The SAUF valve-integrated variant is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X185
- ✓ 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 SU63X185 FAQ
Yes, the AirTAC SU63X185 is discontinued. The direct replacement is the SAU63X185. It matches the 63mm bore, 185mm stroke, 1559N push force, 3/8" port, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
At 0.5MPa it provides 1559N push and 1402N pull; at 0.7MPa push is 2182N, and the theoretical max is 318kgf at 1.0MPa. This specific SKU lacks a magnet and cannot accept a sensor. If sensing is required, order an -S SAU model and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
