This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X175N, 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 SU63X175N
The AirTAC SU63-100 Standard Cylinder SU63X175N 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 SAU63X175N, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X175N
The AirTAC SU63X175N is a discontinued double-acting profile-type cylinder with a 63 mm bore and 175 mm stroke. Because this legacy unit is end-of-life, the direct replacement is the SAU63X175N, which preserves the exact body profile, 3/8" port, M16x1.5 rod thread and SC-series mounting. This NBR-sealed variant operates from -20 to +70 C, generating 1559 N of push force at 0.5 MPa.
Two key upgrades exist in the SAU line: it supports modern CMSG/DMSG/EMSG sensors, whereas this older SU chassis used CS1-B/DS1-B switches. Additionally, the SAU family introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X175N 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 SAU63X175N 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 SU63X175N Is Used
Mid-Tonnage Pressing
Applies the 1559 N push force at 0.5 MPa for seating bearings, stamping light sheet metal, or securely clamping heavy machined components during secondary operations.
Pallet Diversion
Utilizes the 175 mm stroke to push heavy pallets onto secondary packaging lines, leveraging the 3/8" port for rapid cycling within the 30-800 mm/s range.
Replacing the Airtac SU63-100 Standard Cylinder SU63X175N with the SAU63X175N
To replace this discontinued SU63X175N, order the SAU63X175N direct equivalent, verifying the 3/8" port, M16x1.5 rod thread and SC-series mounting hardware. Because this specific SKU lacks a magnet (-S), it cannot accept a magnetic sensor; if sensing is required, you must transition to an SAU-S model and adopt the current CMSG/DMSG/EMSG switch family. 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, while an 80 mm bore offers 2513 N. Note that a standard cylinder drifts without live air, so fit an external rod lock or pilot-operated check valve for load holding. At 175 mm stroke, side-load and rod-bending risks are moderate, but ensure adequate guide support.
Replacement checklist
- ✓ Same bore / stroke → SAU63X175N
- ✓ 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 SU63X175N FAQ
Yes, the SU63X175N is discontinued. The direct replacement is the AirTAC SAU63X175N, which matches the 63 mm bore, 175 mm stroke, 3/8" port, force output and SC-series mounting accessories.
The 63 mm bore delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a 318 kgf maximum at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept sensors; the SAU replacement uses CMSG/DMSG/EMSG switches.
