This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X630SH, 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 SU50X630SH
The AirTAC SU32~50 Standard Cylinder SU50X630SH 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 SAU50X630SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X630SH
The AirTAC SU50X630SH 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, featuring a 1/4" port and M16x1.5 rod thread. The direct replacement is the SAU50X630SH, matching the exact bore, stroke, output force, port size, and SC-series mounting accessories.
This unit includes a high-temperature Viton H seal (0-150 C) and a piston magnet for legacy CS1-B/DS1-B switches; the SAU successor upgrades sensors to CMSG/DMSG/EMSG and offers a new SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X630SH 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 SAU50X630SH 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 SU50X630SH Is Used
High-Temp Diverting
Actuating diverter gates on hot material conveyors where the Viton H seal withstands ambient temperatures up to 150 C.
Extended Reach Ejection
Pushing molded parts out of a hot press area over a 630mm distance, requiring external guides to prevent rod bending.
Thermal Processing Transfer
Moving components into heat treat zones, utilizing the 982 N push force to handle 50 kg loads with a safe margin.
Replacing the Airtac SU32~50 Standard Cylinder SU50X630SH with the SAU50X630SH
To replace this discontinued SU50X630SH, order the SAU50X630SH direct equivalent, verifying the 50mm bore, 630mm stroke, 1/4" port, M16x1.5 thread, and SC-series mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. The -H Viton seal handles up to 150 C. For sizing alternatives, a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. With a 630mm stroke, use external guides to prevent rod bending and side loads. The cylinder does not hold load without air; add an external rod lock for vertical applications.
Replacement checklist
- ✓ Same bore / stroke → SAU50X630SH
- ✓ 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 SU50X630SH FAQ
Yes, the SU50X630SH is discontinued. The direct replacement is the AirTAC SAU50X630SH, which shares the same 50mm bore, 630mm stroke, 1/4" port, force, and SC-series mounting.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. The -S magnet works with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
