This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-100, 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 SUJ50X150-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-100 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 SAUJ50X150-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-100
The AirTAC SUJ50X150-100 is a double-acting double-rod profile cylinder with a 50mm bore and 150mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 100mm on-site, yielding a usable 50-150mm end position. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ50X150-100 model is discontinued and the direct replacement is the SAUJ50X150-100, retaining the same profile body, bore, force, and FA/LB mounting. Because this specific SKU lacks a magnet, it cannot take a magnetic switch; upgrading to the SAUJ also transitions you from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-100 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 SAUJ50X150-100 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 SUJ50X150-100 Is Used
Variable Depth Boring
Adjust the extend stroke on-site by up to 100mm to machine varying pocket depths without retooling the entire fixture.
Variable Length Diverter
Trim the actuator extension from 150mm down to 50mm to deflect different package sizes accurately on a moving belt.
Adjustable Push-Off Arm
Fine-tune the pusher end position in the field to handle changing pallet widths or variable container depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-100 with the SAUJ50X150-100
To replace the discontinued SUJ50X150-100, order the direct replacement SAUJ50X150-100, which matches the 50mm bore, 150mm max stroke, 100mm adjust window, 1/4" port, and FA/LB mounting. The 100mm adjust window is ideal when you need precise field tuning of the extend stroke without swapping cylinders. Because this non-magnet SKU cannot accept sensors, migrating to the SAUJ lets you use current CMSG/DMSG/EMSG switches (the SUJ used CS1-B/DS1-B). For strokes of 300mm or longer, verify side-load limits to prevent guide wear. The stop screw sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-100
- ✓ 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 SUJ50X150-100 FAQ
Yes, the SUJ50X150-100 is discontinued. The direct replacement is the SAUJ50X150-100, which shares the same 50mm bore, 150mm max stroke, 100mm adjust window, 1/4" port, and FA/LB mounting.
The external stop screw allows you to shorten the extend stroke by up to 100mm on-site, giving a usable 50-150mm stroke. The stop sets end position only and is not a load lock.
