This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X165S, 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 SU63X165S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X165S is a double-acting profile-type standard cylinder with a Ø63mm bore and 165mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X165S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X165S
The AirTAC SU63X165S is a discontinued double-acting profile-type cylinder with a 63mm bore and 165mm stroke. Because 165mm is not a standard factory stroke, it was supplied as a non-standard length (typically machined from a 175mm base). Generating 1559N push and 1402N pull at 0.5MPa via a 3/8" port, it is replaced direct by the SAU63X165S. The SAU retains the exact extruded aluminium body, M16x1.5 rod thread, and SC-series mounting accessories.
Two key upgrades exist in the SAU swap: the legacy CS1-B/DS1-B reed switches on this -S magnet model are superseded by current CMSG/DMSG/EMSG sensors, and the SAU line introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered. Note that a plain cylinder drifts without live air; the cushions only decelerate.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X165S 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 SAU63X165S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×165 | 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 SU63X165S Is Used
Package Diverting
Actuates routing gates on 50kg class conveyor lines, using the 1559N thrust to push parcels smoothly without overshooting.
Pallet Stopper
Serves as a robust pneumatic stop for medium-weight pallets, decelerating loads with its 21mm adjustable cushions.
Clamp Actuation
Drives mid-sized machining clamps requiring a 165mm reach, securely holding workpieces within a compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X165S with the SAU63X165S
To replace this SU63X165S, order the SAU63X165S. Verify your 3/8" port tubing, the M16x1.5 rod thread, and your SC-series mounting brackets (LB/FA/FB/CA/CB), as all are unchanged. Because this unit has the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the CMSG/DMSG/EMSG family. If you need integrated air control, consider the SAUF valve-cylinder variant. For sizing alternatives, dropping to a 50mm bore yields 982N push at 0.5MPa, while stepping up to an 80mm bore provides 2513N. At 165mm stroke the side-load risk is low, but always guide the load to prevent rod bending. Finally, remember the air cushions only decelerate; for static holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X165S
- ✓ 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 SU63X165S FAQ
Yes, the SU63X165S is discontinued. The direct replacement is the SAU63X165S. It shares the identical 63mm bore, 165mm stroke, 3/8" port, output force, and SC-series mounting, so it drops straight into the same application.
The SAU63X165S outputs 1559N push and 1402N pull at 0.5MPa, 2182N at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because your SU model has the -S magnet, you must swap legacy CS1-B/DS1-B switches for the modern CMSG/DMSG/EMSG sensor family on the SAU.
