This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X160-40S, 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 SUJ32X160-40S
The AirTAC SUJ Adjustable Cylinder SUJ32X160-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X160-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X160-40S
The AirTAC SUJ32X160-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable 120-160 mm extension out of the 160 mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ32X160-40S is discontinued; the direct replacement is the SAUJ32X160-40S, which retains the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit uses CS1-B/DS1-B switches (indicated by the -S suffix). 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 for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X160-40S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X160-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SUJ32X160-40S Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without changing the entire cylinder setup.
Variable Height Sealing
Trims the extend stroke up to 40 mm to accommodate varying package heights on a sealing line, ensuring consistent contact pressure.
Adjustable Transfer Stops
Fields tune the extend position to act as a mechanical stop for different product lengths on a conveyor, allowing rapid format changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X160-40S with the SAUJ32X160-40S
To replace the discontinued SUJ32X160-40S, order the direct replacement SAUJ32X160-40S, ensuring you switch the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. The 40 mm adjust window is ideal if your end-stop varies by up to 40 mm; for fixed positions, a standard SAU cylinder suffices. FA and LB mounts are supported. Because the 160 mm stroke exceeds 300 mm, verify side-load limits to prevent rod bending. Remember the external stop trims extension but does not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X160-40S
- ✓ 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 SUJ32X160-40S FAQ
Yes, the SUJ32X160-40S is discontinued. The direct replacement is the SAUJ32X160-40S, which matches the 32 mm bore, 160 mm stroke, 1/8" port, and FA/LB mounting. You must upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 40 mm adjust window, allowing the extend stroke to be shortened from 160 mm down to 120 mm on-site. The stop sets end position but does not lock the load.
