This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X500TC, 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 SU50X500TC
The AirTAC SU32~50 Standard Cylinder SU50X500TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 500mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X500TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X500TC
The AirTAC SU50X500TC is a discontinued double-acting profile-type cylinder with a 50mm bore and 500mm stroke. AirTAC replaced this unit with the SAU50X500TC, a direct replacement retaining the exact 1/4" port, M16x1.5 rod thread, TC mounting interface, and compact extruded aluminum body.
Because this specific SKU lacks a magnet, it cannot accept a position switch. If sensing is required, the SAU upgrade family supports modern CMSG/DMSG/EMSG switches (replacing the legacy CS1-B/DS1-B), and the SAUF variant even integrates a built-in 4M solenoid valve. Note that on a 500mm stroke, external guides are recommended to prevent rod bending under side loads, and an external rod lock is required to hold a load securely.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X500TC 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 SAU50X500TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X500TC Is Used
Long-Stroke Diversion
Drives a 500mm diverting arm on a packaging line to route products into secondary lanes using the 982 N push force at 0.5 MPa.
Pallet Push-Off
Actuates a push-off mechanism to slide stacked cartons onto a pallet, utilizing the TC mount for stable mid-stroke traversal.
Replacing the Airtac SU32~50 Standard Cylinder SU50X500TC with the SAU50X500TC
To replace the discontinued SU50X500TC, order the SAU50X500TC. Verify your 1/4" port thread (PT, G, or NPT) and confirm the TC mounting accessory matches your SC-series bracket. Since this SKU has no magnet (-S), it cannot support sensors; if you need position detection, specify an SAU50X500TC-S and upgrade to CMSG/DMSG/EMSG switches. For sizing, the 50mm bore provides 982 N push at 0.5 MPa; if you need more force, step up to the 63mm bore (1559 N), or drop to 40mm (628 N) for lighter loads. With a 500mm stroke, use external guides to mitigate rod-bending side loads. For load holding on air loss, add a pilot-operated check valve or external rod lock, as the cushions only decelerate at stroke ends.
Replacement checklist
- ✓ Same bore / stroke → SAU50X500TC
- ✓ 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 SU50X500TC FAQ
Yes, the SU50X500TC is discontinued. The direct replacement is the AirTAC SAU50X500TC. It shares the same 50mm bore, 500mm stroke, 1/4" port, TC mounting, and output force. The body profile is identical, so it fits the same space.
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 air cushions only decelerate the piston near stroke end; they do not hold the load. For load holding on air loss, you must use an external rod lock or pilot-operated check valve.
