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

About the Airtac SUJ Adjustable Cylinder SUJ40X160-30
The AirTAC SUJ40X160-30 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 out of the 160 mm nominal maximum. It features a 1/4" port, an M12x1.25 rod thread, and 21 mm adjustable air cushions at each end. This SUJ series is discontinued; the direct replacement is the SAUJ40X160-30, matching the bore, stroke, force, port, and FA/LB mounting.
Because this SKU lacks a magnet (-S), it cannot accept a magnetic switch. Note that the stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for held loads. The SAUJ upgrade also transitions to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-30 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 SAUJ40X160-30 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 SUJ40X160-30 Is Used
Variable Stroke Clamping
Adjusts the extend stop on-site to clamp parts of varying heights without reprogramming the pneumatic controller.
Variable Position Diverter
Tunes the extend stroke to deflect different package sizes on a conveyor line precisely at the required push-off distance.
Adjustable Forming Stop
Sets accurate material fold depths in packaging machinery by trimming the extend stroke within the 30 mm window.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-30 with the SAUJ40X160-30
To replace the discontinued SUJ40X160-30, order the direct replacement SAUJ40X160-30, which retains the 40 mm bore, 160 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 30 mm adjust window when you need precise 130-160 mm extend tuning on-site. Since this non-magnetic SKU cannot take a switch, the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For the 160 mm stroke, verify side-load limits on the rod end. The stop screw sets end position and is not a lock; add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-30
- ✓ 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 SUJ40X160-30 FAQ
Yes, the SUJ40X160-30 is discontinued. The direct replacement is the SAUJ40X160-30, matching 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.
The external stop screw window is 30 mm, allowing you to shorten the 160 mm nominal extend stroke down to 130 mm on-site. The stop sets end position and is not a load lock.
