This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X175, 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 SU63X175
The AirTAC Airtac SU63-100 Standard Cylinder SU63X175 is a double-acting profile-type standard cylinder with a Ø63mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X175, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X175
The AirTAC SU63X175 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 175 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this legacy unit with the SAU63X175 direct replacement, matching the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because the body is an extruded aluminum profile, it is shorter and more compact than an ISO 15552 cylinder of the same bore. Note that this non-magnet SKU cannot accept a sensor, and the SAU upgrade switches to CMSG/DMSG/EMSG switches while adding a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X175 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 SAU63X175 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 SU63X175 Is Used
Package Diverting
Actuates diverting arms on packaging lines where the 1559 N push force at 0.5 MPa easily redirects moderate-weight cartons.
Pallet Stopping
Functions as a robust end-stop for pallets on roller conveyors, utilizing the 175 mm stroke to clear the path when retracted.
Replacing the Airtac SU63-100 Standard Cylinder SU63X175 with the SAU63X175
To replace this discontinued SU63X175, order the SAU63X175. Confirm the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are retained. Because this is a no-magnet SKU, it cannot take a sensor; if you need position detection, the SAU replacement requires current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. For sizing both ways, a 50 mm bore offers 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. At 175 mm stroke, side-load and rod-bending risks are low, but ensure proper guide alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU63X175
- ✓ 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 SU63X175 FAQ
Yes, the AirTAC SU63X175 is discontinued. The direct replacement is the SAU63X175. It shares the identical 63 mm bore, 175 mm stroke, 1559 N output force at 0.5 MPa, 3/8 inch port, and SC-series mounting, fitting the same application.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf theoretical max at 1.0 MPa. This specific non-magnet SKU cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
