This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-100, 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.
Airtac SUJ Adjustable Cylinder SUJ50X100-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-100 is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X100-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-100
The AirTAC SUJ50X100-100 is a double-acting double-rod profile cylinder with a 50 mm bore and 100 mm nominal stroke, featuring a 1/4" port and M16x1.5 rod thread. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, setting the exact end position.
The direct replacement is the SAUJ50X100-100, matching the bore, stroke, force, and SC-series FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note this non-magnet SKU cannot take a switch. The stop screw is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X100-100 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.
Where the Airtac SUJ Adjustable Cylinder SUJ50X100-100 Is Used
Custom Fixture Positioning
Trimming the extend stroke by up to 100 mm on-site allows operators to dial in the exact clamping position for varying part sizes without changing the cylinder.
Variable Length Diverter
An external stop screw provides a field-tuned end position to deflect different package lengths on a line, offering precise routing without re-engineering the station.
Adjustable Depth Pusher
Shorten the extend stroke on-site to push products to specific shelf depths, accommodating varied container dimensions using the full 100 mm adjustment window.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-100 with the SAUJ50X100-100
To replace the discontinued SUJ50X100-100, order the direct replacement SAUJ50X100-100, which preserves the 50 mm bore, 100 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The 100 mm adjust window is ideal when you need precise field tuning of the extend stroke from 0 to 100 mm. Since this is a non-magnet model, it cannot accept sensors; if sensing is needed, move to an SAUJ with the -S option and use CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-100
- ✓ 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 SUJ50X100-100 FAQ
Yes, the SUJ50X100-100 is discontinued. The direct replacement is the SAUJ50X100-100, which matches the 50 mm bore, 100 mm stroke, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors and the SAUF built-in-valve variant.
This double-acting double-rod cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushing 1374 N at 0.7 MPa and 1767 N at 0.9 MPa, with a 200 kgf max at 1.0 MPa. The external stop screw provides a 100 mm adjust window to trim the extend stroke on-site. The stop sets end position and is not a load lock.
