This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X575, 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 SU63X575
The AirTAC SU63-100 Standard Cylinder SU63X575 is a double-acting profile-type standard cylinder with a Ø63mm bore and 575mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X575, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X575
The AirTAC SU63X575 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 575 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X575, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept position sensors. The SAU upgrade adds a sensor groove for current CMSG/DMSG/EMSG switches (the SU line used legacy CS1-B/DS1-B) and introduces the SAUF built-in 4M valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X575 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 SAU63X575 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 SU63X575 Is Used
Long-Stroke Diversion
Pushes heavy pallets 575 mm across a transfer line using the 1559 N thrust at 0.5 MPa, requiring external guides to absorb side loads.
Mid-Force Clamping
Secures large fabrications during machining, applying up to 318 kgf maximum holding force at 1.0 MPa within a compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X575 with the SAU63X575
To replace the SU63X575, order the SAU63X575 and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. This non-magnetic SKU cannot support switches; if sensing is needed, specify an SAU with a magnet and use CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For higher loads, the adjacent 80 mm bore provides 2513 N push at 0.5 MPa, while the 50 mm bore offers 982 N if downsizing. A plain cylinder drifts without live air, so use an external rod lock or pilot-operated check valve for load holding. At 575 mm, the stroke demands external guide rails to prevent rod bending under side loads. The SAUF variant integrates a valve if faster actuation is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X575
- ✓ 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 SU63X575 FAQ
Yes, the AirTAC SU63X575 is discontinued. The direct replacement is the SAU63X575. It matches the 63 mm bore, 575 mm stroke, 1559 N force, 3/8" port, and SC-series mounting accessories, so it fits the same application without modification.
At 0.5 MPa it provides 1559 N push and 1402 N pull, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take sensors. The SAU replacement supports CMSG/DMSG/EMSG switches, whereas the old SU used CS1-B/DS1-B sensors.
