This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-10, 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 SUJ40X160-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-10 is a double-acting profile-type standard cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X160-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-10
The AirTAC SUJ40X160-10 is a discontinued double-acting double-rod profile cylinder with a 160 mm nominal stroke and a 10 mm external stop screw window, allowing you to trim the extend stroke down to 150 mm on-site. This stop screw strictly sets the end position; it is not a load lock.
The direct replacement is the SAUJ40X160-10, preserving the bore, stroke, force, port, and FA/LB mounting. This SKU has no magnet (-S omitted) and cannot take a switch, whereas the SAUJ upgrades to current CMSG/DMSG/EMSG sensors. Plain cylinders drift on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-10 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X160-10 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 SUJ40X160-10 Is Used
Diverter Gate Tuning
Trimming the 160 mm extend stroke by up to 10 mm on-site lets operators dial in the exact diverter gate angle without machining a custom-length cylinder.
Product Stop Positioning
A 10 mm external stop window provides the micro-adjustment needed to fine-tune a conveyor product stop, accommodating minor package size variations.
Sealing Head Clearance
Adjustable end-positioning ensures a sealing head can be backed off slightly from the nominal 160 mm stroke to prevent crushing delicate packaging materials.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-10 with the SAUJ40X160-10
To replace the SUJ40X160-10, order the SAUJ40X160-10 for an direct match. Select the adjust window based on your on-site trim needs; here, the 10 mm window allows a 150-160 mm extend stroke. Mounting uses FA or LB brackets (SC-series compatible). Because this specific SKU lacks a magnet, it cannot support sensing; the SAUJ requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-10
- ✓ 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 SUJ40X160-10 FAQ
Yes, the SUJ40X160-10 is discontinued. The direct replacement is the SAUJ40X160-10, which matches the 40 mm bore, 160 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw offers a 10 mm adjust window, meaning the usable extend stroke can be trimmed from 160 mm down to 150 mm on-site. The stop sets end position and is not a load lock.
