This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-40, 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 SUJ Adjustable Cylinder SUJ63X200-40 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 SAUJ63X200-40, which matches its bore, stroke, force and mounting.
The AirTAC SUJ63X200-40 is a discontinued double-acting double-rod profile cylinder with a 63 mm bore and 200 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable extend range of 160-200 mm. This compact aluminum barrel body is shorter than an ISO 15552 unit of the same bore. The 3/8" port and M16x1.5 rod thread handle flows for speeds of 30-800 mm/s.
Because this model is end-of-life, the direct replacement is the SAUJ63X200-40, which preserves the bore, stroke, force, 3/8" port, and FA/LB mounting. Two key upgrade facts apply: the SAUJ uses current CMSG/DMSG/EMSG sensors whereas this legacy SUJ used CS1-B/DS1-B switches, and the SAU line adds an SAUF built-in-valve variant the SU series lacked. Note this SKU has no magnet and cannot take a sensor; the stop screw sets end position but is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-40 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ63X200-40 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.
Bends or stamps parts to different lengths on the same fixture by dialing the extend stroke down 40 mm on-site without swapping cylinders.
Tunes the pusher extension precisely to clear varying package widths on a packaging line, preventing over-travel damage.
Sets custom end positions for different pallet stack heights, allowing quick manual adjustment of the stop screw for each run.
To replace the discontinued SUJ63X200-40, order the direct replacement SAUJ63X200-40, which matches the 63 mm bore, 200 mm nominal stroke, 3/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your mechanism requires field tuning the extend stroke down to 160 mm; if fixed positioning is acceptable, a standard SAU cylinder with an external stop may suffice. Because this specific SKU lacks a magnet, it cannot accept sensors; if you need position detection, select the -S version of the SAUJ and migrate to CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the SUJ63X200-40 is discontinued. The direct replacement is the SAUJ63X200-40, which matches the 63 mm bore, 200 mm stroke, 3/8" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.
The external stop screw provides a 40 mm adjust window, shortening the 200 mm extend stroke down to 160 mm on-site. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ63X200-40 replacement — usually within 7-8 hours.
