This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X850-100S, 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 SUJ100X850-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X850-100S is a double-acting profile-type standard cylinder with a Ø100mm bore and 850mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X850-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X850-100S
The AirTAC SUJ100X850-100S is a double-acting double-rod profile cylinder with an on-site stroke-trim window, letting you shorten the extend stroke by up to 100 mm for a usable 750-850 mm range. The nominal 850 mm is the maximum. It features a 1/2 inch port, a 25 mm rod, and 29 mm adjustable cushions. The direct replacement is the SAUJ100X850-100S, retaining the same force, mounting, and bore.
Two key upgrades exist in the SAUJ: the legacy CS1-B/DS1-B sensors are replaced by current CMSG/DMSG/EMSG switches, and the SAU line adds an SAUF built-in-valve variant. The external stop screw sets the end position but is not a load lock; drift occurs on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X850-100S 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 SAUJ100X850-100S 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 SUJ100X850-100S Is Used
Variable-Length Ejector
Tuning the extend stroke on-site by up to 100 mm allows an ejection mechanism to handle varying part depths without swapping the entire cylinder.
Adjustable Transfer Stop
A 750-850 mm extend window lets operators reposition a transfer stopper block precisely for different product widths on a packaging line.
Multi-Position Divert
Trimming the extend stroke dynamically creates multiple physical divert positions for sorting items into distinct lanes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X850-100S with the SAUJ100X850-100S
To replace the discontinued SUJ100X850-100S, use the exact direct replacement SAUJ100X850-100S, which matches the 100 mm bore, 850 mm stroke, 100 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 100 mm adjust window when you need maximum field flexibility to trim the extend stroke. For the -S magnet option, note the sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. Because the 850 mm stroke is long, account for side-load and rod-bending by using external guides to prevent premature wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X850-100S
- ✓ 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 SUJ100X850-100S FAQ
Yes, the SUJ100X850-100S is discontinued. The direct replacement is the SAUJ100X850-100S, which matches the 100 mm bore, 850 mm stroke, 100 mm adjust window, and 1/2 inch port. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting double-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw window is 100 mm, allowing you to trim the extend stroke from the 850 mm maximum down to 750 mm. The stop sets end position and is not a load lock.
