This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X510SH, 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 SU50X510SH
The AirTAC SU32~50 Standard Cylinder SU50X510SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 510mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X510SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X510SH
The AirTAC SU50X510SH is a discontinued double-acting profile-type cylinder with a 50mm bore and 510mm stroke. The direct replacement is the SAU50X510SH, matching the exact bore, stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting.
This -H variant uses Viton seals for 0-150 C environments. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked. The 510mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X510SH 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 SAU50X510SH 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 SU50X510SH Is Used
Hot End Diversion
Uses the Viton -H seal to withstand 150 C ambient heat while pushing 982 N at 0.5 MPa to route parts on a conveyor.
Pallet Push-Off
The 510mm stroke pushes totes to an adjacent lane; add external guides to prevent rod bending over this long travel.
High-Temp Transfer
Shifts workpieces between ovens with a 60 kg safe vertical lift margin, relying on the 1/4" port for rapid actuation.
Replacing the Airtac SU32~50 Standard Cylinder SU50X510SH with the SAU50X510SH
To replace this SU50X510SH, order the SAU50X510SH direct: it preserves the 50mm bore, 510mm stroke, 1/4" port, and SC-series mounting. If sizing alternatives, a 40mm bore gives 628 N push while a 63mm bore yields 1559 N at 0.5 MPa. Because the 510mm stroke is long, use external guides to prevent rod bending under side loads. The -H Viton seal handles 0-150 C heat. The -S magnet switches from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. The cushion only decelerates; for load holding on air loss, install an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X510SH
- ✓ 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 SU50X510SH FAQ
Yes, the SU50X510SH is discontinued. The direct replacement is the SAU50X510SH. It shares the same 50mm bore, 510mm stroke, output force, 1/4" port, and SC-series mounting accessories. You can order the SAU50X510SH directly as a physical replacement.
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 on this legacy SU used CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
