This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-75S, 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 SUJ40X160-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-75S 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 SAUJ40X160-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-75S
The AirTAC SUJ40X160-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 85-160 mm from the 160 mm nominal maximum. The extruded aluminum profile barrel is shorter than a standard cylinder of the same bore.
This SUJ40X160-75S is discontinued and the direct replacement is the SAUJ40X160-75S, retaining the same bore, stroke, force, port, and FA/LB mounting. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAUJ successor upgrades to current CMSG/DMSG/EMSG sensors. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-75S 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 SAUJ40X160-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×160 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ40X160-75S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to control drill penetration depth precisely without swapping cylinders for different material thicknesses.
Variable Length Diverter
Trims the extend stroke to deflect varying package sizes on a conveyor, ensuring positive contact without overtravel.
Adjustable Pusher Stops
Sets custom end positions for pushing cartons into packing lanes, allowing rapid format changes directly at the machine.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-75S with the SAUJ40X160-75S
To replace the discontinued SUJ40X160-75S, order the direct replacement SAUJ40X160-75S, which matches the 40 mm bore, 160 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 75 mm adjust window if your application requires trimming the extend stroke down to a minimum of 85 mm on-site. Note that the -S magnet on the legacy model used CS1-B/DS1-B switches, which must be upgraded to CMSG/DMSG/EMSG sensors on the SAUJ. Because the stroke is 160 mm, verify side-load alignment to prevent rod binding. The stop screw sets end position and is not a lock; add an external rod lock for load holding without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-75S
- ✓ 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 SUJ40X160-75S FAQ
Yes, the SUJ40X160-75S is discontinued. The direct replacement is the SAUJ40X160-75S, which matches the 40 mm bore, 160 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the -S piston magnet switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
The external stop screw window is 75 mm, allowing you to shorten the 160 mm nominal extend stroke down to a minimum of 85 mm on-site. The stop sets end position and is not a load lock.
