This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X145, 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 SU63X145
The AirTAC Airtac SU63-100 Standard Cylinder SU63X145 is a double-acting profile-type standard cylinder with a Ø63mm bore and 145mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X145, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X145
The AirTAC SU63X145 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 145 mm stroke. Delivering 1559 N push force at 0.5 MPa, its direct replacement is the SAU63X145. This upgrade preserves the original 3/8" port, M16x1.5 rod thread, and SC-series mounting dimensions, ensuring a seamless retrofit without altering your existing framework.
Because this specific SKU lacks a magnet, it cannot accept position sensors. The SAU series modernizes this by utilizing current CMSG/DMSG/EMSG switches on its -S variants, replacing the legacy CS1-B/DS1-B units. For applications needing integrated flow control, the SAUF variant offers a built-in 4M solenoid valve that the SU line never featured.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X145 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 SAU63X145 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 SU63X145 Is Used
Package Diverting
Ideal for pushing medium-weight cartons off a main transport line, utilizing the 1559 N push force at 0.5 MPa to reliably overcome side friction.
Pallet Stopping
Functions as a robust end-stop for inbound pallets on low-profile roller conveyors, absorbing kinetic energy via its 21 mm adjustable air cushions.
Clamp Actuation
Drives medium-duty workholding clamps on machining fixtures, providing secure holding pressure without requiring the full 1.0 MPa capacity.
Replacing the Airtac SU63-100 Standard Cylinder SU63X145 with the SAU63X145
To replace the discontinued SU63X145, order the SAU63X145 and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this original SKU has no magnet (-S), it cannot support sensing; if your upgrade requires position feedback, specify an SAU63X145S and switch to the modern CMSG/DMSG/EMSG sensor family. Sizing both ways: dropping to a 50 mm bore reduces push force to 982 N at 0.5 MPa, while stepping up to an 80 mm bore increases it to 2513 N. Remember that a standard cylinder does not hold load on air loss—the cushion only decelerates near stroke end—so add an external rod lock or pilot-operated check valve for suspended loads. For higher flow demands, explore the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X145
- ✓ 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 SU63X145 FAQ
Yes, the AirTAC SU63X145 is discontinued and end-of-life. The direct replacement is the SAU63X145. It shares the identical 63 mm bore, 145 mm stroke, output force, 3/8" port, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull force, increasing to 2182 N push at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept magnetic sensors; the SAU -S replacement uses CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
