This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X350STC, 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 SU32X350STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X350STC, which matches its bore, stroke, force and mounting.
The AirTAC SU32X350STC is a discontinued double-acting profile-type cylinder with a 32 mm bore and 350 mm stroke, delivering 402 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU32X350STC, a direct alternative retaining the exact bore, stroke, output force, 1/8" port, and SC-series TC mounting interface.
The compact extruded aluminium body is shorter than an ISO 15552 cylinder of the same bore. This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors, while the SAU line also introduces a SAUF built-in 4M valve variant the SU lacked.

The SAU32X350STC 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.
Actuates a lightweight routing gate on a packaging line, using the 350 mm stroke to shift small parcels between adjacent belts.
Pushes completed plastic mouldings out of a press area, leveraging the 402 N push force to clear light components safely.
Functions as an automated stopper pin in a 32 mm bore assembly cell, holding items in place for a robotic pick before retracting.
To replace this SU32X350STC, order the SAU32X350STC, confirming the 32 mm bore, 350 mm stroke, 1/8" port (default PT thread), M10x1.25 rod end, and TC mounting accessory are retained. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors on the new SAU. If you need higher force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa; if you need less, investigate smaller profiles. For the 350 mm stroke, use an external guide to prevent rod bending and side-load damage. The air cushions only decelerate the piston near stroke end; they do not hold the load. For static holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
Yes, the SU32X350STC is discontinued. The direct replacement is the AirTAC SAU32X350STC. It matches the 32 mm bore, 350 mm stroke, 1/8" port, and TC mounting interface. The only change is that the -S magnet on the SAU works with current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting 32 mm bore cylinder has a 1/8" air port. The thrust is 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X350STC replacement — usually within 7-8 hours.
