This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X800, 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 SU63X800
The AirTAC Airtac SU63-100 Standard Cylinder SU63X800 is a double-acting profile-type standard cylinder with a Ø63mm bore and 800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X800, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X800
The AirTAC SU63X800 is a discontinued double-acting profile-type cylinder with an 800 mm stroke and 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a theoretical 318 kgf. The direct replacement is the SAU63X800, matching the exact bore, stroke, output force, 3/8" port, and SC-series mounting. The extruded aluminium profile body is more compact than an ISO 15552 cylinder of the same size.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in 4M solenoid valve variant the SU line lacked. Because this specific SKU lacks a magnet, it cannot accept a magnetic switch. Note that an 800 mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X800 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 SAU63X800 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 SU63X800 Is Used
Long-Stroke Diversion
Pushes heavy pallets 800 mm laterally across high-speed packaging conveyors where the 1559 N push force at 0.5 MPa handles loaded transfers reliably.
Large Door Actuation
Opens and closes heavy industrial machine guard doors over an 800 mm travel distance, utilising the 21 mm adjustable air cushions to decelerate the 63 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X800 with the SAU63X800
To replace the discontinued SU63X800, order the SAU63X800 direct equivalent, verifying the 63 mm bore, 800 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). If sizing alternatives, the adjacent 80 mm bore yields 2513 N push at 0.5 MPa, while the 50 mm bore provides 982 N. For this 800 mm stroke, add external guides to prevent rod bending from side loads. A plain cylinder drifts on air loss since cushions only decelerate; use an external rod lock or pilot-operated check valve for load holding. If self-switching is needed, the SAUF variant integrates a 4M valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU63X800
- ✓ 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 SU63X800 FAQ
Yes, the AirTAC SU63X800 is discontinued and end-of-life. The direct replacement is the SAU63X800. It shares the identical 63 mm bore, 800 mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting accessories, fitting the same application directly.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N at 0.7 MPa, and 2805 N at 0.9 MPa. This specific SKU has no magnet and cannot take a sensor. If you previously used a -S magnet on the SU line with CS1-B/DS1-B switches, the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
