This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X600TC, 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 SU63-100 Standard Cylinder SU63X600TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X600TC, which matches its bore, stroke, force and mounting.
The AirTAC SU63X600TC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 600 mm stroke. Built with an extruded aluminum barrel and adjustable air cushions at both ends, it delivers 1559 N push and 1402 N pull at 0.5 MPa via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X600TC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a position switch. If sensing is needed on the upgrade path, the SAU family uses current CMSG/DMSG/EMSG sensors, whereas the older SU line relied on legacy CS1-B/DS1-B switches. The SAU series also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU never offered.

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.
Pushes heavy pallets or workpieces along a 600 mm path, utilizing the 1559 N thrust at 0.5 MPa to overcome friction on roller conveyors.
Provides consistent 1402 N pull force to seat large components or draw parts over the extended 600 mm travel, guided externally to avoid rod bending.
To replace the discontinued SU63X600TC, order the SAU63X600TC, confirming the 63 mm bore, 600 mm stroke, M16x1.5 rod thread, 3/8" port, and TC mounting accessory are retained for a direct. When sizing, check neighboring bores: a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N, ensuring the 63 mm class at 1559 N is optimal. Note that this non-magnetic SKU cannot support sensors, whereas the SAU upgrade transitions to CMSG/DMSG/EMSG switches. A plain double-acting cylinder does not hold load on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for suspended loads. Finally, the 600 mm stroke demands attention to side-load and rod-bending risks; implement an external guide to prevent premature seal wear.
Replacement checklist
Yes, the SU63X600TC is discontinued. The direct replacement is the AirTAC SAU63X600TC. It shares the identical 63 mm bore, 600 mm stroke, output force, 3/8" port, and TC mounting, so it fits the same application without mechanical modifications.
At 0.5 MPa it provides 1559 N push and 1402 N pull, increasing to 2182 N push at 0.7 MPa and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if sensing is required.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X600TC replacement — usually within 7-8 hours.
