This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-10S, 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 SUJ40X160-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-10S 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 SAUJ40X160-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-10S
The AirTAC SUJ40X160-10S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 150-160 mm extension out of the 160 mm nominal maximum.
The direct replacement is the SAUJ40X160-10S, which preserves the 1/4" port, M12x1.25 rod thread, and 21 mm adjustable cushions. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. 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. The SAUJ upgrade also switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-10S 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 SAUJ40X160-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ40X160-10S
| 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 SUJ40X160-10S Is Used
Diverter Gate Positioning
Fine-tunes the 150-160 mm extend stroke on-site to set exact contact angles on conveyor sorting gates without machining spacers.
Variable Carton Sealing
Adjusts the extend endpoint within the 10 mm window to accommodate minor flap height variances during packaging line changeovers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-10S with the SAUJ40X160-10S
To replace the discontinued SUJ40X160-10S, specify the direct replacement SAUJ40X160-10S, which retains the 40 mm bore, 160 mm stroke, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window if you need precise 150-160 mm extend tuning; for larger trims, select a model with a wider stop screw range. Because this unit has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-10S
- ✓ 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 SUJ40X160-10S FAQ
Yes, the SUJ40X160-10S is discontinued. The direct replacement is the SAUJ40X160-10S, which matches the 40 mm bore, 160 mm stroke, 1/4" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw allows trimming the extend stroke by up to 10 mm on-site, giving a usable 150-160 mm extension. The stop sets end position but is not a load lock.
