This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD50X60S, 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 Airtac SUD Series Double Rod Cylinder SUD50X60S is a double-acting profile-type standard cylinder with a Ø50mm bore and 60mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD50X60S, which matches its bore, stroke, force and mounting.
The AirTAC SUD50X60S is a double-acting, double-rod profile cylinder featuring a 50mm bore and 60mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. This discontinued model is directly replaced by the SAUD50X60S, which retains the exact 1/4" port, M16x1.5 rod thread, and 21mm adjustable cushions.
Because the second rod drives a sensor cam and resists rotation, double-rod designs excel in multi-tool actuation. The built-in magnet (-S) supports legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. Note that cushions only decelerate; use an external rod lock for load holding.

The SAUD50X60S 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.
Simultaneously drives two opposing tools from one compact profile body, utilizing the equal both-ways force to maintain balanced actuation.
The twin rods prevent piston twisting during side-loaded diverting tasks on packaging lines, ensuring precise component placement.
Lifts platforms vertically with equal push and pull force, using the back rod to mount CS1-B/DS1-B sensors for end-of-stroke confirmation.
To replace the discontinued SUD50X60S, order the direct replacement SAUD50X60S, matching the 50mm bore, 60mm stroke, and FA/LB mounting. When sizing both ways, verify the equal push/pull force fits your load, stepping to neighbouring bores (40mm or 63mm) if needed. Choose a double-rod cylinder when anti-rotation or a back rod for a sensor cam is required. For the -S magnet, upgrade from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For strokes >=300mm, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the SUD50X60S is discontinued. The direct replacement is the SAUD50X60S, which matches the 50mm bore, 60mm stroke, 1/4" port, and FA/LB mounting. You only need to upgrade the -S sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The 1/4" port feeds a double-rod design where force is equal both ways: 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUD50X60S replacement — usually within 7-8 hours.
