This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X305SH, 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 SU50X305SH
The AirTAC SU32~50 Standard Cylinder SU50X305SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 305mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X305SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X305SH
The AirTAC SU50X305SH is a discontinued double-acting profile-type cylinder with a 50mm bore, 305mm stroke, and Viton H high-temperature seals (0-150 C). Delivering 982 N push at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU50X305SH, matching the 1/4" port, M16x1.5 rod thread, and SC-series mounting.
Two key upgrades exist in the SAU swap: the legacy CS1-B/DS1-B sensors are replaced by current CMSG/DMSG/EMSG switches, and the new SAUF variant offers a built-in 4M solenoid valve the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X305SH 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 SAU50X305SH 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 SU50X305SH Is Used
Hot End Ejection
Uses the Viton H seals to withstand 150 C ambient heat while pushing parts out of a molding station with 982 N force.
High-Temp Diverting
Actuates a diverter gate over 305mm to route heated components, benefiting from the compact profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU50X305SH with the SAU50X305SH
To replace this SU50X305SH, order the SAU50X305SH. Confirm the 50mm bore, 305mm stroke, 1/4" port (PT/G/NPT), and SC-series mounting (LB/FA/FB/CA/CB). Because the original has an -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. The -H Viton seal provides 0-150 C heat resistance. Sizing both ways: a 40mm bore yields 628 N push, while a 63mm bore yields 1559 N. For the 305mm stroke, use external guides to prevent rod bending and side-load wear. This cylinder will not hold a load without live air; use an external rod lock or pilot-operated check valve for holding, as the cushion only decelerates. If you need self-switching, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU50X305SH
- ✓ 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 SU50X305SH FAQ
Yes, the SU50X305SH is discontinued. The direct replacement is the SAU50X305SH. It matches the 50mm bore, 305mm stroke, 982 N force, 1/4" port, and SC-series mounting. You must upgrade your sensors: the old CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG switches on the SAU.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. The -H seal option allows operation from 0 to 150 C. The 1/4" port size is fixed by the bore, and speed ranges from 30-800 mm/s.
