This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X160-20, 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 SUJ100X160-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X160-20 is a double-acting profile-type standard cylinder with a Ø100mm bore and 160mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X160-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X160-20
The AirTAC SUJ100X160-20 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 140-160 mm extend out of the 160 mm nominal maximum. The stop screw sets the end position but is not a lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
This SUJ model is discontinued; the direct replacement is the SAUJ100X160-20, sharing the bore, stroke, force, port, and SC-series FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B. This non-magnet SKU cannot take a switch.

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 SAUJ100X160-20 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 SUJ100X160-20 Is Used
Press Fit Tuning
Trimming the 160 mm extend stroke by up to 20 mm on-site allows precise press-fit depth alignment for varying bearing housings without machining hard stops.
Divertor Gate Adjustment
Field-tuning the extend endpoint lets operators adjust divertor gate reach on the fly to accommodate different package widths on the line.
Pallet Stop Positioning
The external stop screw provides a method to set exact pallet stopping locations at the end of the extend stroke, adaptable to pallet length variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X160-20 with the SAUJ100X160-20
To replace the discontinued SUJ100X160-20, order the direct replacement SAUJ100X160-20, keeping the 160 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. Since this SKU lacks a magnet, it cannot take a switch; if sensing is needed, move to an SAUJ-S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. The 20 mm adjust window is ideal when exact extend endpoints vary by fixture, beating a fixed SAU plus external stop. For this 160 mm stroke side-load is minimal, but for strokes >=300 mm verify rod bearing load. Remember the stop screw sets position, not a lock; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X160-20
- ✓ 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 SUJ100X160-20 FAQ
Yes, the SUJ100X160-20 is discontinued. The direct replacement is the SAUJ100X160-20, which matches the 100 mm bore, 160 mm stroke, 20 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 100 mm bore 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 (max 801 kgf at 1.0 MPa). The external stop screw window is 20 mm, shortening the 160 mm nominal extend stroke to a usable 140-160 mm on-site. The stop sets end position and is not a load lock.
