This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X90-40S, 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 SUJ32X90-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X90-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 90mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X90-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X90-40S
The AirTAC SUJ32X90-40S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40mm on-site, yielding a usable 50-90mm stroke from the 90mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It delivers 402N push and 345N pull at 0.5MPa, rising to 563N push at 0.7MPa. The bore dictates a 1/8" port and a Ø12mm rod with an M10x1.25 thread.
Because this model is end-of-life, the exact drop-in replacement is the SAUJ32X90-40S, which retains the same 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. For sizing, a safe working load is roughly 241N (60% of the 402N push figure), translating to a 20kg vertical lift with a 2:1 margin. Note the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X90-40S 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 SAUJ32X90-40S produces the same force from the same bore — a true drop-in on output. 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 SUJ32X90-40S Is Used
Variable Depth Spotting
Machine tapping or spotting operations where the extend stroke must be dialed in precisely between 50 and 90mm to accommodate different material thicknesses without changing the cylinder.
Adjustable Transfer Pusher
Sorting or diverting parts on a line when product sizes change frequently, allowing operators to shorten the extend stroke by up to 40mm on-site to prevent overtravel.
Tunable Forming Stop
Packaging equipment that requires field stroke tuning to set precise forming depths, using the external stop screw to define the exact end position for varied container dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X90-40S with the SAUJ32X90-40S
To replace the discontinued SUJ32X90-40S, specify the SAUJ32X90-40S drop-in, keeping the 32mm bore, 90mm stroke, 40mm adjust window, and 1/8" port. If you need more force, the neighboring 40mm bore provides 628N push at 0.5MPa; if less force is acceptable, step down accordingly. Choose the 40mm adjust window if you need wide on-site tuning of the extend stroke from 50 to 90mm. Mounting remains compatible with AirTAC SC series FA and LB brackets. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X90-40S
- ✓ 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 SUJ32X90-40S FAQ
Yes, the SUJ32X90-40S is discontinued. The exact drop-in replacement is the SAUJ32X90-40S, which matches the 32mm bore, 90mm stroke, 40mm adjust window, and 1/8" port. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting single-rod cylinder provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and 724N push at 0.9MPa, with a theoretical max of 82kgf at 1.0MPa. The external stop screw allows you to trim the extend stroke by up to 40mm on-site, giving a usable stroke range of 50-90mm. The stop sets end position but is not a load lock.
