This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X75CB, 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 SU40X75CB
The AirTAC Airtac SU32~50 Standard Cylinder SU40X75CB is a double-acting profile-type standard cylinder with a Ø40mm bore and 75mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X75CB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X75CB
The AirTAC SU40X75CB is a discontinued double-acting profile-type cylinder with a 40mm bore and 75mm stroke. It delivers 628N push and 528N pull at 0.5MPa through a 1/4" port. The direct replacement is the SAU40X75CB, matching the bore, stroke, force, port and SC-series CB mounting.
This extruded aluminium body is more compact than an ISO 15552 equivalent. Note this non-magnetic SKU cannot take a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X75CB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X75CB 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 SU40X75CB Is Used
Clamp Actuation
Provides 628N of push force at 0.5MPa to secure medium workpieces in machining or welding fixtures.
Package Diversion
Drives a 75mm stroke diverter arm to route small to mid-size cartons on packaging lines.
Gating Mechanism
Operates lightweight access gates or sorting flaps using the compact CB mounting bracket.
Replacing the Airtac SU32~50 Standard Cylinder SU40X75CB with the SAU40X75CB
To replace this discontinued SU40X75CB, order the SAU40X75CB direct equivalent, verifying the 40mm bore, 75mm stroke, 1/4" port, M12x1.25 rod thread and CB mounting. Because this specific SKU lacks a magnet, it cannot accept a sensor; if position detection is needed on the SAU, specify the -S option and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing alternatives, a 32mm bore provides 402N push at 0.5MPa, while a 50mm bore offers 982N. Remember that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU40X75CB
- ✓ 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 SU40X75CB FAQ
Yes, the SU40X75CB is discontinued. The direct replacement is the SAU40X75CB. It matches the 40mm bore, 75mm stroke, 628N push force at 0.5MPa, 1/4" port and SC-series CB mounting.
At 0.5MPa it provides 628N push and 528N pull; at 0.7MPa it pushes 879N, and the theoretical maximum is 128kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches.
