This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD32X450S, 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 SUD Series Double Rod Cylinder SUD32X450S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X450S is a double-acting profile-type standard cylinder with a Ø32mm bore and 450mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD32X450S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X450S
The AirTAC SUD32X450S is a double-acting, double-rod profile cylinder featuring a 32 mm bore, 450 mm stroke, and a 1/8 inch port. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This model is discontinued and end-of-life; the direct replacement is the SAUD32X450S, which retains the same bore, stroke, force, port, and FA/LB mounting.
The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam. This SUD32X450S includes a piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X450S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUD32X450S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUD Series Double Rod Cylinder SUD32X450S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×450 | Stroke length in mm. |
| -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 SUD Series Double Rod Cylinder SUD32X450S Is Used
Gripping Transfer Unit
Uses the equal both ways force to grip and move components on a conveyor without stroke direction affecting clamp pressure.
Dual-Tool Drive Station
The second protruding rod drives an auxiliary cam or secondary mechanism simultaneously from the rear end of the cylinder.
Vertical Lift Stopper
Provides stable anti-rotation lifting of an 18 kg payload using the back rod as a guided cam for a packaging line diverter.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X450S with the SAUD32X450S
To replace the discontinued SUD32X450S, drop in the SAUD32X450S directly; body, bore, stroke, equal both ways force, and FA/LB mounting remain unchanged. When sizing both ways, verify that 345 N @0.5 MPa is sufficient, or step up to the neighboring 40 mm bore for 528 N. Choose a double rod when you need anti-rotation or a back rod to drive a second tool. If your SUD used the -S magnet for CS1-B/DS1-B switches, upgrade to CMSG/DMSG/EMSG sensors for the SAUD. For this 450 mm stroke, add external guides to prevent rod bending and side-load wear. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X450S
- ✓ 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 SUD Series Double Rod Cylinder SUD32X450S FAQ
Yes, the SUD32X450S is discontinued. The direct replacement is the SAUD32X450S, which matches the 32 mm bore, 450 mm stroke, 1/8 inch port, and equal both ways force. You only need to upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The double-rod design ensures force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Operating speed is 30-800 mm/s.
