This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X670SH, 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 SU40X670SH
The AirTAC SU32~50 Standard Cylinder SU40X670SH is a double-acting profile-type standard cylinder with a Ø40mm bore and 670mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X670SH, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X670SH
The AirTAC SU40X670SH is a discontinued double-acting profile-type cylinder with a 40mm bore and 670mm stroke. Delivering 628 N push and 528 N pull at 0.5 MPa, its direct replacement is the SAU40X670SH. The SAU retains the identical extruded aluminium body, 1/4" port, M12x1.25 rod thread, and SC-series mounting, ensuring a seamless swap.
Because this SKU includes the -H seal, it supports 0-150 C high-temperature operation via Viton FKM. The -S magnet originally paired with legacy CS1-B/DS1-B switches, but the SAU successor upgrades to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X670SH 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 SAU40X670SH 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 SU40X670SH Is Used
Hot-End Product Transfer
Pushes packaged goods along a heat-exposed conveyor using the 670mm stroke and Viton -H seals rated for 150 C environments.
Thermoforming Ejection
Acts as a double-acting ejector in molding lines, delivering 628 N of push force while enduring ambient thermal radiation.
Replacing the Airtac SU32~50 Standard Cylinder SU40X670SH with the SAU40X670SH
To replace this SU40X670SH, order the SAU40X670SH. Verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting (LB, FA, FB, CA, CB, TC). The -H Viton seal is retained for 150 C environments. If stepping up to a 50mm bore, the push force at 0.5 MPa increases to 982 N; stepping down to 32mm drops it to 402 N. The -S magnet means you must migrate from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. At 670mm, this long stroke demands external guiding to prevent rod bending under side loads. Note: the cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU40X670SH
- ✓ 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 SU40X670SH FAQ
Yes, the SU40X670SH is discontinued. The direct replacement is the SAU40X670SH. It shares the identical 40mm bore, 670mm stroke, 1/4" port, output force, and SC-series mounting accessories. You simply order the SAU equivalent.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it pushes 879 N, reaching a theoretical max of 128 kgf at 1.0 MPa. The -S magnet on this legacy model worked with CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
