This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75H, 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 SU32X75H
The AirTAC SU32~50 Standard Cylinder SU32X75H is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X75H, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X75H
The AirTAC SU32X75H is a discontinued double-acting profile-type cylinder with a 32mm bore and 75mm stroke. Featuring a Viton H seal for 0-150C environments, it delivers 402N push force at 0.5MPa. The direct replacement is the SAU32X75H, matching the bore, stroke, 1/8" port, and SC-series mounting.
This compact extruded-aluminum body is shorter than an ISO 15552 equivalent. The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF valve-integrated option, while this no-magnet SKU cannot accept switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75H 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 SAU32X75H 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 SU32X75H Is Used
Hot End Ejection
Ideal for pushing small parts out of heated molds using the Viton H 0-150C seal, delivering a safe 241N working load at 0.5MPa.
Compact Clamping
The short extruded profile body clamps small workpieces in tight machining cells where an ISO 15552 cylinder would not fit.
Diverting Arms
Provides a fast 75mm stroke to actuate lightweight routing gates on packaging lines, reusing existing AirTAC SC-series mounts.
Replacing the Airtac SU32~50 Standard Cylinder SU32X75H with the SAU32X75H
To replace this discontinued SU32X75H, order the SAU32X75H. Confirm the 32mm bore, 75mm stroke, 1/8" port, M10x1.25 rod thread, and high-temperature Viton H seal (0-150C). Because this SKU lacks a magnet (-S), it cannot accept position sensors; the SAU upgrade uses CMSG/DMSG/EMSG switches if you add the -S option. For sizing, the 40mm bore offers higher force (628N push at 0.5MPa), while the 25mm bore is smaller. The 75mm stroke is under the 300mm side-load threshold, but always guide the load to prevent rod bending. A plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding. The SAUF variant adds a built-in 4M solenoid valve if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X75H
- ✓ 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 SU32X75H FAQ
Yes, the SU32X75H is discontinued. The direct replacement is the SAU32X75H. It matches the 32mm bore, 75mm stroke, 1/8" port, output force, and SC-series mounting accessories, fitting the same application directly.
At 0.5MPa it pushes 402N and pulls 345N; at 0.7MPa it pushes 563N, with a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet, so it cannot take sensors. The SAU replacement supports CMSG/DMSG/EMSG switches if you order the -S variant.
