This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X135-50, 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 SUJ100X135-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X135-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 135mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X135-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X135-50
The AirTAC SUJ100X135-50 is a discontinued double-acting double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 85-135 mm extension out of the 135 mm nominal maximum. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
Because the SUJ line is end-of-life, the direct replacement is the SAUJ100X135-50, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Note this specific SKU lacks a magnet and cannot take a switch. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X135-50 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 SAUJ100X135-50 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 SUJ100X135-50 Is Used
Variable Stroke Pressing
Allows operators to fine-tune the extend stroke on-site by up to 50 mm to accommodate material thickness variations in pressing tasks.
Adjustable Diverter Arms
Enables field adjustment of the extend end position to handle different package sizes on a packaging line without changing the cylinder.
Variable Depth Stops
Provides a customizable hard stop for pallet positioning, letting operators trim the 135 mm stroke down to 85 mm as load dimensions change.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X135-50 with the SAUJ100X135-50
To replace the discontinued SUJ100X135-50, order the direct replacement SAUJ100X135-50, which matches the 100 mm bore, 135 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 50 mm adjust window if you need to trim the extend stroke on-site between 85 and 135 mm. Because this non-magnetic SKU cannot accept sensors, migrating to the SAUJ allows adding CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. Remember the stop screw is not a load lock; add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X135-50
- ✓ 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 SUJ100X135-50 FAQ
Yes, the SUJ100X135-50 is discontinued. The direct replacement is the SAUJ100X135-50, matching the 100 mm bore, 135 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 50 mm adjust window, allowing you to trim the extend stroke from the 135 mm maximum down to 85 mm. The stop sets end position and is not a load lock.
