This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X205TC, 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 SU63X205TC
The AirTAC SU63-100 Standard Cylinder SU63X205TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 205mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X205TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X205TC
The AirTAC SU63X205TC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 205 mm stroke. It produces 1559 N push force at 0.5 MPa via a 3/8 inch port. AirTAC replaced this end-of-life unit with the SAU63X205TC, a direct replacement retaining the exact bore, stroke, output force, port size, and TC mounting interface.
This nonstandard 205 mm stroke exceeds the catalog standard but is fully supported. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet, so it cannot accept sensors; the SAU upgrade uses CMSG/DMSG/EMSG switches for -S variants.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X205TC 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 SAU63X205TC 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 SU63X205TC Is Used
Package Diversion
Actuates routing gates on packaging lines, using the 1559 N push force at 0.5 MPa to deflect heavy cartons reliably.
Pallet Handling
Provides the extended 205 mm throw needed to position pallets on TC-mounted stops, with a 79 kg vertical lift margin.
Clamp Actuation
Secures workpieces during machining, where the compact profile body saves space compared to standard ISO cylinders.
Replacing the Airtac SU63-100 Standard Cylinder SU63X205TC with the SAU63X205TC
To replace this discontinued SU63X205TC, order the SAU63X205TC. Confirm the 63 mm bore, 205 mm stroke, 3/8 inch port (default PT thread), M16x1.5 rod thread, and the SC-series TC mounting accessory. Because this nonstandard 205 mm stroke exceeds the 1500 mm standard catalog limit, verify guide support to prevent rod bending under side loads. If sizing alternatives, the neighboring 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. This plain cylinder cannot hold a load without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for vertical holding. The SAU family also offers the SAUF variant with a built-in 4M solenoid valve, an option the SU line lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU63X205TC
- ✓ 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 SU63X205TC FAQ
Yes, the SU63X205TC is discontinued. The direct replacement is the AirTAC SAU63X205TC. It matches the 63 mm bore, 205 mm stroke, 3/8 inch port, output force, and TC mounting. The SAU body is identical, but if you previously used a magnet-equipped -S variant, note the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 3/8 inch port feeds a piston delivering 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet and cannot accept sensors. The air cushions only decelerate the load near stroke end; they do not hold position on air loss.
