This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X525S, 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 SU63X525S
The AirTAC SU63-100 Standard Cylinder SU63X525S is a double-acting profile-type standard cylinder with a Ø63mm bore and 525mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X525S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X525S
The AirTAC SU63X525S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 525 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a 318 kgf theoretical maximum. AirTAC replaced this unit with the SAU63X525S, a direct sharing the exact bore, stroke, output force, 3/8" port, and SC-series mounting hardware.
This extruded aluminium profile body is more compact than a same-bore ISO 15552 unit. The SAU upgrade retains these mechanics but shifts -S magnet sensors to the modern CMSG/DMSG/EMSG family from the legacy CS1-B/DS1-B. The SAU line also introduces the SAUF built-in 4M solenoid valve option, which the SU series lacked.

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 SAU63X525S 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 SU63X525S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a high-speed line using the 1559 N push force at 0.5 MPa, with the 525 mm stroke clearing wide conveyor frames.
Long Reach Ejection
Extends 525 mm to eject finished metal parts from a press bed, requiring external guide rails to absorb side-load impacts and prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU63X525S with the SAU63X525S
To replace the SU63X525S, order the SAU63X525S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because the -S magnet is present, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need integrated flow control, explore the SAUF variant with its built-in valve. For sizing alternatives, a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. At 525 mm, this long stroke demands external guide rails to prevent rod bending under side loads. Finally, the cushions only decelerate; use an external rod lock or pilot-operated check valve to hold loads securely without live air.
Replacement checklist
- ✓ Same bore / stroke → SAU63X525S
- ✓ 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 SU63X525S FAQ
Yes, the AirTAC SU63X525S is discontinued and end-of-life. The direct replacement is the SAU63X525S. It shares the identical 63 mm bore, 525 mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting, so it drops straight into the same application.
This double-acting cylinder pushes 1559 N and pulls 1402 N at 0.5 MPa, pushes 2182 N at 0.7 MPa, and reaches a 318 kgf maximum at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU, you must switch to current CMSG/DMSG/EMSG sensors.
