This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X660S, 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 SU63X660S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X660S is a double-acting profile-type standard cylinder with a Ø63mm bore and 660mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X660S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X660S
The AirTAC SU63X660S is a discontinued double-acting profile-type cylinder featuring a 63 mm bore and 660 mm stroke. Delivering 1559 N push force at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this unit with the SAU63X660S, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting.
The -S magnet on this legacy unit worked with CS1-B/DS1-B switches, whereas the SAU successor uses CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF valve-integrated option, which the SU line lacked. Note that standard cushions only decelerate; they do not hold loads pneumatically.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X660S 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 SAU63X660S 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 SU63X660S Is Used
Pallet Diverting
Uses the 1559 N push force at 0.5 MPa to push heavy pallets sideways off a main conveyor line onto a secondary packing branch.
Vertical Lift Gate
Raises a 79 kg mezzanine safety gate using the 660 mm stroke, requiring external guides to prevent rod bending during vertical transit.
Component Ejection
Ejects machined metal parts from a fixture, relying on the 21 mm adjustable air cushions at both ends to decelerate the 660 mm travel smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X660S with the SAU63X660S
To replace the SU63X660S, order the SAU63X660S, confirming the 63 mm bore, 660 mm stroke, 3/8" port (PT/G/NPT), and SC-series mounting hardware. Because the -S magnet is present, prepare to upgrade from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For sizing alternatives, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. At 660 mm, this long stroke demands external guide rails to prevent rod bending under side loads. A plain cylinder drifts without live air, so use an external rod lock or pilot-operated check valve for load holding. If you need integrated control, explore the SAUF variant featuring a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X660S
- ✓ 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 SU63X660S FAQ
Yes, the SU63X660S is discontinued. The direct replacement is the SAU63X660S, which matches the 63 mm bore, 660 mm stroke, 3/8" port, output force, and SC-series mounting. You must only swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches.
It features a 3/8" air port. The force outputs are: 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. The piston speed ranges from 30-800 mm/s.
