This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1800, 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 SU63X1800
The AirTAC SU63-100 Standard Cylinder SU63X1800 is a double-acting profile-type standard cylinder with a Ø63mm bore and 1800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1800, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1800
The AirTAC SU63X1800 is a discontinued double-acting profile-type cylinder with an 1800 mm stroke and 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa. Because 1800 mm exceeds the 1500 mm standard maximum for this bore, it is a non-standard, made-to-order unit. The direct replacement is the SAU63X1800, matching the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in 4M valve option the SU lacked. This bare SKU has no magnet, so it cannot accept a switch. Note that 1800 mm strokes require external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X1800 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 SAU63X1800 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 SU63X1800 Is Used
Long-Stroke Material Push
Transfers heavy pallets across a 1.8-meter conveyor gap, utilizing the 1559 N push force at 0.5 MPa with external guides to prevent rod bending.
High-Bay Ejection
Ejects packaged goods from vertical storage racks where a 79 kg safe vertical lift capacity and extended reach are required for automated retrieval.
Large Door Actuation
Opens and closes heavy industrial machinery safety doors over a 1800 mm span, relying on adjustable 21 mm end cushions to decelerate the load smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1800 with the SAU63X1800
To replace this discontinued SU63X1800, order the SAU63X1800 direct equivalent, verifying the 3/8 inch port, M16x1.5 thread, and SC-series mounting. If sizing alternatives, the adjacent 80 mm bore yields 2513 N push at 0.5 MPa, while the 50 mm bore yields 982 N. Because this is a bare cylinder without a magnet (-S), it cannot accept legacy CS1-B/DS1-B or modern CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss, as the 21 mm cushions only decelerate; use an external rod lock or pilot-operated check valve for load holding. At 1800 mm, external guides are mandatory to prevent side-load rod bending. The SAUF variant adds a built-in valve if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1800
- ✓ 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 SU63X1800 FAQ
Yes, the AirTAC SU63X1800 is discontinued and end-of-life. The direct replacement is the SAU63X1800. It offers the same 63 mm bore, 1800 mm stroke, output force, 3/8 inch port, and SC-series mounting. You simply order the SAU equivalent.
This double-acting cylinder provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf maximum at 1.0 MPa. This specific SKU lacks a magnet, meaning it cannot accept position sensors. The SAU replacement uses CMSG/DMSG/EMSG switches for the -S variant.
