This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X630, 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 SU32~50 Standard Cylinder SU50X630
The AirTAC SU32~50 Standard Cylinder SU50X630 is a double-acting profile-type standard cylinder with a Ø50mm bore and 630mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X630, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X630
The AirTAC SU50X630 is a discontinued double-acting profile-type cylinder with a 50mm bore and 630mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X630, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors (replacing the old CS1-B/DS1-B) and adds an optional SAUF built-in 4M valve. This non-magnet SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X630 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X630 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 SU32~50 Standard Cylinder SU50X630 Is Used
Long-Stroke Diversion
Pushes packages across a 630mm lane on a sorting conveyor, utilizing the 982 N thrust at 0.5 MPa to overcome guide friction.
Replacing the Airtac SU32~50 Standard Cylinder SU50X630 with the SAU50X630
To replace this discontinued SU50X630, order the SAU50X630 direct equivalent. Confirm your 1/4" port, M16x1.5 rod thread, and SC-series mounting. Because this is a non-S SKU, it lacks a magnet and cannot hold a sensor; if you need position detection, select an SAU-S model and use CMSG/DMSG/EMSG switches. For the 630mm stroke, use an external guide to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock for held loads. Neighbouring bores: 40mm yields 628 N push, while 63mm yields 1559 N at 0.5 MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU50X630
- ✓ 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 SU32~50 Standard Cylinder SU50X630 FAQ
Yes, the SU50X630 is discontinued. The direct replacement is the AirTAC SAU50X630. It shares the same 50mm bore, 630mm stroke, 1/4" port, output force, and SC-series mounting, so it drops right into the same application.
This 50mm bore cylinder delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N at 0.7 MPa, and a 200 kgf theoretical max at 1.0 MPa. This specific SKU has no magnet (-S) and cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches.
