This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100SN, 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 SU63X100SN
The AirTAC Airtac SU63-100 Standard Cylinder SU63X100SN is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X100SN
The AirTAC SU63X100SN is a discontinued double-acting profile-type cylinder with a 63 mm bore and 100 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X100SN, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting.
This SU unit includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU series lacked. The NBR seal supports standard -20 to +70 C operation.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X100SN 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 SAU63X100SN 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 SU63X100SN Is Used
Package Diverting
Pushes medium-weight cartons off a main transport line using the 1559 N push force, with the 100 mm stroke clearing side guides quickly.
Clamp Actuation
Secures aluminum extrusions or steel brackets during machining operations, providing stable holding via the 1402 N pull force.
Pallet Stopper
Acts as a pneumatic stop gate for incoming pallets, absorbing impact using the adjustable 21 mm air cushions at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X100SN with the SAU63X100SN
To replace this SU63X100SN, order the SAU63X100SN, confirming the 63 mm bore, 100 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new SAU cylinder. If your application needs integrated airflow control, consider the SAUF valve-integrated variant. When sizing, the 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa; if you need less force, a 50 mm bore provides 982 N push, while an 80 mm bore offers 2513 N. A plain cylinder does not hold load without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAU63X100SN
- ✓ 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 SU63X100SN FAQ
Yes, the SU63X100SN is discontinued. The direct replacement is the AirTAC SAU63X100SN. It shares the identical 63 mm bore, 100 mm stroke, 1559 N output force, 3/8" port, and SC-series mounting, so it fits the same application without mechanical modifications.
At 0.5 MPa, it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, with a theoretical maximum of 318 kgf at 1.0 MPa. Because this is an -S magnet model, it originally used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors instead.
