This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50SH, 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 SU50X50SH
The AirTAC SU32~50 Standard Cylinder SU50X50SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50SH
The AirTAC SU50X50SH is a discontinued double-acting profile-type cylinder with a 50mm bore, 50mm stroke, and a Viton H high-temperature seal (0-150 C). It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X50SH, a direct replacement retaining the exact bore, stroke, output force, and SC-series mounting.
When upgrading to the SAU50X50SH, the body dimensions and 20 mm piston rod are unchanged, but the sensor family changes: this SU's -S magnet works with legacy CS1-B/DS1-B switches, whereas the SAU uses current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X50SH 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 SAU50X50SH 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 SU50X50SH Is Used
Hot End Ejection
Uses the Viton H seal to withstand 150 C ambient heat while pushing parts with 982 N at 0.5 MPa.
Divert Arm Actuation
Short 50 mm stroke provides rapid diverting force on packaging lines, fitting neatly into SC mounts.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50SH with the SAU50X50SH
To replace the SU50X50SH, order the SAU50X50SH. Confirm the 1/4" port, M16x1.5 rod thread, PT thread standard, and your SC-series mounting hardware (LB/FA/FB/CA/CB) all carry over directly. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must be swapped to CMSG/DMSG/EMSG sensors on the new cylinder. The -H Viton seal allows 0-150 C operation, so verify your ambient temperature requires it. If sizing alternatives, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore yields 1559 N. A plain cylinder drifts without live air; the 21 mm cushions only decelerate, so add an external rod lock or pilot-operated check valve for load holding. At 50 mm stroke, side-load bending is minimal, but ensure rigid guidance for heavy loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50SH
- ✓ 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 SU50X50SH FAQ
Yes, the SU50X50SH is discontinued. The direct replacement is the SAU50X50SH. It shares the same 50 mm bore, 50 mm stroke, 1/4" port, and SC-series mounting, but the SAU uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
It has a 1/4" port. The force ratings are: 982 N push and 825 N pull at 0.5 MPa; 1374 N push at 0.7 MPa; 1767 N push at 0.9 MPa; and a theoretical maximum of 200 kgf at 1.0 MPa.
