This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-30S, 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 SUJ40X160-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-30S 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 SAUJ40X160-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-30S
The AirTAC SUJ40X160-30S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 130-160 mm extend window from the 160 mm nominal maximum. The extruded aluminum profile barrel is more compact than an ISO 15552 cylinder of the same bore. This SUJ40X160-30S model is discontinued; the direct replacement is the SAUJ40X160-30S, retaining the 40 mm bore, 1/4" port, M12x1.25 rod thread, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B sensors, whereas the SAUJ replacement upgrades to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-30S 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 SAUJ40X160-30S 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 SUJ40X160-30S Is Used
Variable Stroke Clamping
Adjusts the extend end position on-site by up to 30 mm to clamp parts of varying widths without re machining the fixture.
Transfer Pusher Alignment
Tunes the pusher extend stroke from 160 mm down to 130 mm to perfectly time part handoff onto a moving conveyor belt.
Carton Forming Stops
Provides field adjustment of the extend stroke to accommodate different carton depths on a packaging line using the 1/4 inch port.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-30S with the SAUJ40X160-30S
To replace the discontinued SUJ40X160-30S, order the direct replacement SAUJ40X160-30S, which matches the 40 mm bore, 160 mm nominal stroke, 30 mm adjust window, 1/4" port, and FA/LB/Basic mounting. Choose the 30 mm adjust window if your fixture needs field-tuning of the extend end position between 130 and 160 mm. For the -S magnet version, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG on the SAUJ. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear. The external stop sets the end position but does not lock the load; add an external rod lock for holding without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-30S
- ✓ 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 SUJ40X160-30S FAQ
Yes, the SUJ40X160-30S is discontinued. The direct replacement is the SAUJ40X160-30S, which matches the 40 mm bore, 160 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
It is a double-acting double-rod cylinder with a 30 mm adjust window, allowing you to shorten the 160 mm extend stroke down to 130 mm on-site. The external stop sets end position but is not a load lock.
