This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X175N, 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 SU100X175N
The AirTAC SU63-100 Standard Cylinder SU100X175N is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X175N, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X175N
The AirTAC SU100X175N is a discontinued double-acting profile-type cylinder with a 100mm bore and 175mm stroke. As an end-of-line product, it is directly replaced by the SAU100X175N. This direct successor maintains the exact extruded aluminium body, 1/2" port, M20x1.5 rod thread, and SC-series mounting, delivering a push force of 3927 N at 0.5 MPa. The NBR seal provides a standard -20 to +70 C operating range.
Because this SKU lacks a magnet (-S), it cannot accept position sensors. Furthermore, the SAU upgrade introduces a built-in 4M solenoid valve option (SAUF) that the legacy SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X175N carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X175N 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 SU100X175N Is Used
Heavy Pressing Operations
Applies the 3927 N push force at 0.5 MPa to seat bearings or assemble heavy mechanical components with consistent pressure.
Material Ejection
Ejects moulded or stamped products from machinery, utilizing the 29 mm adjustable air cushions to decelerate the rod at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU100X175N with the SAU100X175N
To replace the SU100X175N, order the SAU100X175N, verifying the 100mm bore, 175mm stroke, 1/2" port, and NBR seals. Since this is a non-magnetic SKU, it cannot accept legacy CS1-B/DS1-B switches, and the SAU replacement would use CMSG/DMSG/EMSG sensors only if you switch to an -S variant. If sizing alternatives, a neighbouring 80mm bore provides 2513 N push at 0.5 MPa, while this 100mm bore reaches 5497 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF valve-integrated body is a new option to explore.
Replacement checklist
- ✓ Same bore / stroke → SAU100X175N
- ✓ 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 SU100X175N FAQ
Yes, the SU100X175N is discontinued. The direct replacement is the SAU100X175N, which matches the 100mm bore, 175mm stroke, 1/2" port, and SC-series mounting accessories.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept position switches; a -S variant would use CS1-B/DS1-B sensors (or CMSG/DMSG/EMSG on the SAU).
