This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X450TC, 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 SU50X450TC
The AirTAC SU32~50 Standard Cylinder SU50X450TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 450mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X450TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X450TC
The AirTAC SU50X450TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 450mm stroke. It delivers 982 N push force at 0.5 MPa via a 1/4 inch port. AirTAC replaced this unit with the SAU50X450TC, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
Buyers gain two upgrades: the SAU uses current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M solenoid valve option. This non-magnet SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X450TC 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 SAU50X450TC 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 SU50X450TC Is Used
Material Diversion
Drives a 50 kg diverter arm along a packaging line, utilizing the 450mm stroke to push cartons cleanly between adjacent conveyor belts.
Vertical Lift Gate
Raises a lightweight access gate up to 450mm, safely operating within the 589 N working load limit to manage gravity during descent.
Component Ejection
Ejects machined parts from a fixture using a TC mount, relying on the 982 N push force at 0.5 MPa to clear stamped metal blanks reliably.
Replacing the Airtac SU32~50 Standard Cylinder SU50X450TC with the SAU50X450TC
To replace this discontinued SU50X450TC, order the SAU50X450TC. Verify your 1/4 inch port, M16x1.5 rod thread, and TC mounting. This non-magnet SKU cannot take a switch. If stepping up, the 63mm bore yields 1559 N push at 0.5 MPa; stepping down to 40mm gives 628 N. Because the stroke is 450mm, use an external guide to prevent rod bending under side loads. Note: air cushions only decelerate; use a rod lock or pilot check valve to hold loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X450TC
- ✓ 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 SU50X450TC FAQ
Yes, the AirTAC SU50X450TC is discontinued. The direct replacement is the SAU50X450TC. It matches the 50mm bore, 450mm stroke, 1/4 inch port, output force, and TC mounting accessories, fitting the same application directly.
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. This specific SKU lacks a magnet, so it cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches.
