This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X860S, 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.

The AirTAC SU32~50 Standard Cylinder SU32X860S is a double-acting profile-type standard cylinder with a Ø32mm bore and 860mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X860S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X860S is a discontinued double-acting profile cylinder with an 860 mm stroke. It delivers 402 N push force at 0.5 MPa and features a 1/8" port. AirTAC replaced this legacy unit with the SAU32X860S, a direct replacement sharing the exact same bore, stroke, force, port size, and SC-series mounting.
Because the 860 mm stroke exceeds the 32 mm bore's 500 mm standard limit, this is a nonstandard stroke requiring external guide support to prevent rod bending. The SAU upgrade retains the compact extruded aluminum body but switches the -S magnet compatibility from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in valve option.

| Max (@1.0 MPa) | 82 kgf | |
The SAU32X860S 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.
Clears finished small parts from a 32 mm bore machining center over a long 860 mm ejection distance.
To replace this discontinued SU32X860S, order the SAU32X860S. Verify your 1/8" port threads (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, TC). Since this 860 mm stroke exceeds the 32 mm bore's 500 mm standard maximum, add external linear guides to prevent rod bending under side loads. If sizing alternatives, a 40 mm bore yields 628 N push at 0.5 MPa, while dropping pressure reduces force. The -S magnet on your original SU worked with CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors. Note that a plain cylinder drifts without live air; 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
Yes, the AirTAC SU32X860S is discontinued. The direct replacement is the SAU32X860S. It shares the identical 32 mm bore, 860 mm stroke, 1/8" port, output force, and SC-series mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32 mm bore has a 1/8" port and generates 402 N push / 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The air cushion is 21 mm at both ends, and speed ranges from 30-800 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X860S replacement — usually within 7-8 hours.
