This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X100-100, 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 SUJ63X100-100 is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X100-100, which matches its bore, stroke, force and mounting.
The AirTAC SUJ63X100-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 0-100 mm extend window from the 100 mm nominal maximum. It features a 20 mm rod, M16x1.5 rod-end thread, 21 mm adjustable cushions, and a 3/8" port. Note this SKU lacks a magnet, so it cannot accept a magnetic switch.
The direct replacement is the SAUJ63X100-100, preserving the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches, and the SAU family adds an SAUF built-in-valve variant. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X100-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAUJ63X100-100 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.
Machine tools needing field stroke tuning to dial in exact boring depths on-site without swapping the entire cylinder.
Conveyor lines requiring a diverter arm with a flexible extend window to handle varying package sizes on the fly.
Pallet handling systems where the external stop screw trims the extend stroke to adapt to different pallet heights.
To replace the discontinued SUJ63X100-100, order the direct replacement SAUJ63X100-100, which matches the 63 mm bore, 100 mm stroke, 3/8" port, and FA/LB mounts. Because this SKU has no magnet, it cannot take sensors; if you need position detection, select the -S version of the SAUJ and use current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Choose the 100 mm adjust window when you need maximum field flexibility to trim the extend stroke. The stop screw sets end position and is not a lock; for held loads, add an external rod lock. If your stroke is 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SUJ63X100-100 is discontinued. The direct replacement is the SAUJ63X100-100, which preserves the 63 mm bore, 100 mm stroke, 318 kgf max force, 3/8" port, and FA/LB mounting. You simply insert an A after the leading S. The SAUJ family also supports current CMSG/DMSG/EMSG sensors and adds the SAUF built-in-valve variant.
This double-acting double-rod cylinder has a 100 mm adjust window, allowing you to trim the extend stroke by up to 100 mm on-site. The 3/8" port and 21 mm cushions ensure stable 30-800 mm/s operation.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ63X100-100 replacement — usually within 7-8 hours.
