This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X185S, 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 SU63X185S
The AirTAC SU63-100 Standard Cylinder SU63X185S 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 SAU63X185S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X185S
The AirTAC SU63X185S is a discontinued double-acting profile-type cylinder with a 63mm bore and 185mm stroke. Delivering 1559N push force at 0.5MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this legacy unit with the SAU63X185S, a direct upgrade retaining the exact 3/8-inch port, M16x1.5 rod thread, output force, and SC-series mounting.
When migrating to the SAU63X185S, your -S magnet equipped model will require current CMSG/DMSG/EMSG sensors, as the older CS1-B/DS1-B switches are obsolete. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X185S 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 SAU63X185S 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 SU63X185S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×185 | 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 SU63X185S Is Used
Package Diverting
Actuates routing gates on 50-80kg parcel lines, using the 1559N thrust to push cartons firmly into secondary sorting chutes.
Pallet Stop Arms
Controls heavy pallet flow on roller conveyors, dropping a 185mm stroke stop pin to arrest inbound loads safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X185S with the SAU63X185S
To replace the SU63X185S, order the SAU63X185S direct equivalent, verifying your 3/8-inch port, M16x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes the -S magnet, you must upgrade your position sensing from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. If sizing alternatives, the neighboring 50mm bore yields 982N push at 0.5MPa, while the 80mm bore provides 2513N. Note that a plain cylinder drifts without live air; the 21mm cushions only decelerate at stroke ends, so fit an external rod lock or pilot-operated check valve for secure load holding. For applications needing integrated flow control, consider the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU63X185S
- ✓ 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 SU63X185S FAQ
Yes, the AirTAC SU63X185S is discontinued and end-of-life. The direct replacement is the SAU63X185S. It shares the identical 63mm bore, 185mm stroke, 3/8-inch port, output force, and SC-series mounting, so it fits the same application directly.
At 0.5MPa it provides 1559N push and 1402N pull force, rising to 2182N push at 0.7MPa, with a theoretical max of 318kgf at 1.0MPa. Because this is the -S magnet version, note that the SAU replacement requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
