This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X50-30, 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.
Airtac SUJ Adjustable Cylinder SUJ100X50-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X50-30 is a double-acting profile-type standard cylinder with a Ø100mm bore and 50mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X50-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X50-30
The AirTAC SUJ100X50-30 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 20-50 mm stroke from the 50 mm nominal maximum. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions. The direct replacement is the SAUJ100X50-30, matching the bore, stroke, force, and mounting.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. Because this SKU lacks a magnet, it cannot take a switch. The SAUJ successor adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B hardware while retaining the compact profile barrel and SC-series FA/LB mounting.

Where the Airtac SUJ Adjustable Cylinder SUJ100X50-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 20-50 mm insertion depth for pins or bearings on-site, compensating for fixture tolerances without re-machining stops.
Variable Format Flaps
Adjusts the extend endpoint on the fly to accommodate different carton depths in packaging lines, ensuring consistent tuck or fold pressure.
Adjustable Diverters
Sets precise divert strokes for changing product widths on a conveyor, using the 30 mm trim window to handle varied package sizes quickly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X50-30 with the SAUJ100X50-30
To replace the discontinued SUJ100X50-30, order the direct replacement SAUJ100X50-30, which preserves the 100 mm bore, 50 mm stroke, 1/2" port, and FA/LB mounting. Choose the 30 mm adjust window if your end position requires on-site tuning between 20 and 50 mm. Since this non-magnetic SKU cannot accept a switch, the SAUJ upgrade path enables modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Note that for any stroke over 300 mm, carefully verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X50-30
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ100X50-30 FAQ
