This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-50, 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 SUJ100X350-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X350-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-50
The AirTAC SUJ100X350-50 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 300-350 mm from the 350 mm nominal maximum. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
Because this model is discontinued, the direct replacement is the SAUJ100X350-50, matching the 100 mm bore, 350 mm stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note that at 350 mm stroke, external guides should be used to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-50 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X350-50 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 SUJ100X350-50 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 50 mm on-site allows operators to dial in exact press-fit depths for large bearings without machining custom spacers.
Variable Length Diverter
Adjusting the extend stop from 300 to 350 mm accommodates different package sizes on a packaging line, letting the diverter reach varying conveyor lanes precisely.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-50 with the SAUJ100X350-50
To replace the discontinued SUJ100X350-50, specify the SAUJ100X350-50 direct: it preserves the 100 mm bore, 350 mm nominal stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 50 mm adjust window when you need precise 300-350 mm extend tuning on-site. Because this SKU lacks a magnet (-S), it cannot take a magnetic switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the SUJ's CS1-B/DS1-B. For the 350 mm stroke, add external guides to manage side-load and rod-bending risks. Remember the stop screw sets end position only and does not lock loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-50
- ✓ 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 SUJ100X350-50 FAQ
Yes, the SUJ100X350-50 is discontinued. The direct replacement is the SAUJ100X350-50, which matches the 100 mm bore, 350 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This double-acting double-rod cylinder has a 50 mm adjust window (usable extend 300-350 mm). The stop screw sets end position but is not a load lock; use an external rod lock for held loads.
