This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X40-40S, 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 SUJ32X40-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X40-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X40-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X40-40S
The AirTAC SUJ32X40-40S is a double-acting, double-rod profile cylinder with a 32 mm bore and 40 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, effectively tuning the usable extend length down to zero without changing the mounting layout. The extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
This SUJ32X40-40S (-S magnet variant) is discontinued and the direct replacement is the SAUJ32X40-40S, which retains the exact bore, stroke, force, 1/8" port, and FA/LB mounting. The upgrade path moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Note that the external stop sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X40-40S 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 SAUJ32X40-40S 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 SUJ32X40-40S Is Used
Variable Pitch Indexing
Tuning the extend stroke on-site by up to 40 mm to accommodate different product lengths in a machining fixture without swapping out the entire actuator assembly.
Adjustable Diverter Gate
Setting a precise push-off distance for varying box sizes on a packaging line, using the external stop to dial in the exact reach required.
Short-Stroke Sorting Pusher
Trimming the extend stroke down to a few millimeters for compact e-commerce sorting operations where full 40 mm travel would jam the mechanism.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X40-40S with the SAUJ32X40-40S
To replace the discontinued SUJ32X40-40S, specify the SAUJ32X40-40S as a direct, ensuring you update the position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. The 40 mm adjust window allows you to trim the extend stroke on-site down to 0 mm, which is often more compact than fitting a fixed SAU cylinder with an external mechanical stop. Mounting is compatible with AirTAC SC series FA and LB brackets. Because the nominal stroke is 40 mm (under 300 mm), side-load rod deflection is minimal, but always verify guide alignment. The stop screw defines the end position and does not function as a load lock; use a pilot-operated check valve or external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X40-40S
- ✓ 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 SUJ32X40-40S FAQ
Yes, the AirTAC SUJ32X40-40S is discontinued. The direct replacement is the SAUJ32X40-40S, which matches the 32 mm bore, 40 mm stroke, 1/8" port, and FA/LB mounting. You will need to upgrade the position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 40 mm adjust window, allowing you to trim the extend stroke on-site from the 40 mm maximum down to 0 mm. The stop sets end position and is not a load lock.
