This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-10, 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 SUJ50X150-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-10 is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X150-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-10
The AirTAC SUJ50X150-10 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 140-150 mm extension out of the 150 mm nominal maximum. This SKU has no magnet and cannot accept a switch.
This SUJ model is discontinued; the direct replacement is the SAUJ50X150-10, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade shifts sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. 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 SAUJ50X150-10 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 SAUJ50X150-10 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.
Where the Airtac SUJ Adjustable Cylinder SUJ50X150-10 Is Used
Probe Contact Tuning
Trimming the final 10 mm of extension on-site to set exact probe contact pressure against a workpiece without machining custom spacers.
Divertor Gate Calibration
Adjusting the extend end position in the field to perfectly mate with varying product sizes on a packaging line.
Pusher Stop Alignment
Dialing in the exact eject stroke to push parts onto a pallet while avoiding collision with an adjacent fixture.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-10 with the SAUJ50X150-10
To replace the discontinued SUJ50X150-10, specify the SAUJ50X150-10 direct, which preserves the 50 mm bore, 150 mm stroke, 1/4" port, and FA/LB mounting. The 10 mm adjust window is ideal for fine-tuning the extend end position without adding an external physical stop. Because this non-magnetic SKU cannot take a switch, migrating to the SAUJ allows the use of current CMSG/DMSG/EMSG sensors. For this 150 mm stroke, ensure your mechanical setup handles side loads, and note that the stop screw only sets the end position—it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-10
- ✓ 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 SUJ50X150-10 FAQ
Yes, the SUJ50X150-10 is discontinued. The direct replacement is the SAUJ50X150-10, which matches the 50 mm bore, 150 mm stroke, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 10 mm, allowing you to shorten the 150 mm nominal extend stroke down to 140 mm on-site. The stop sets the end position and is not a load lock.
