This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-30, 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 SUJ Adjustable Cylinder SUJ63X200-30 is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X200-30, which matches its bore, stroke, force and mounting.
The AirTAC SUJ63X200-30 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 170-200 mm extend out of the 200 mm nominal maximum. The 3/8" port and M16x1.5 rod end are fixed by the bore. This SUJ model is discontinued; the direct replacement is the SAUJ63X200-30, matching the bore, stroke, force, port, and FA/LB mounting.
Because the stop screw only sets the end position, it is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for held loads. This non-magnet SKU cannot take a switch. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ63X200-30 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.
Trimming the extend stroke by up to 30 mm on-site allows an ejection pin to hit different material thicknesses without swapping the entire cylinder.
A 170-200 mm extend window lets operators fine-tune the physical stop position on a conveyor lane for changing package dimensions.
Field-adjusting the gate extend length by up to 30 mm ensures precise sorting angles for varying product widths without re-plumbing the pneumatics.
To replace the discontinued SUJ63X200-30, order the direct replacement SAUJ63X200-30 directly; bore, stroke, 30 mm adjust window, 3/8" port, and FA/LB mounting remain identical. Choose the 30 mm adjust window if you need field tuning of the extend end position; a fixed SAU plus external stop lacks this integrated trim. For mounting, use SC-series compatible FA or LB brackets. Because this SKU lacks a magnet, it cannot take a sensor; the SAUJ upgrade moves to CMSG/DMSG/EMSG switches (the SUJ used legacy CS1-B/DS1-B). At a 200 mm stroke, side-load alignment is moderate, but for any stroke 300 mm or longer, carefully align rod guidance to prevent binding.
Replacement checklist
Yes, the SUJ63X200-30 is discontinued. The direct replacement is the SAUJ63X200-30, which matches the 63 mm bore, 200 mm stroke, 30 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 30 mm adjust window, shortening the 200 mm nominal extend stroke down to 170 mm on-site. The stop sets end position only; it is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ63X200-30 replacement — usually within 7-8 hours.
