This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X100-50S, 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 SUJ32X100-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X100-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X100-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X100-50S
The AirTAC SUJ32X100-50S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 50-100 mm extend out of the 100 mm nominal maximum. 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.
This SUJ model is discontinued; the direct replacement is the SAUJ32X100-50S, matching the 32 mm bore, 100 mm stroke, 50 mm adjust window, force, 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).

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X100-50S 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 SAUJ32X100-50S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×100 | 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 SUJ32X100-50S Is Used
Variable Pitch Pushing
Feeding parts of differing lengths on a line by dialing the extend stroke from 50 to 100 mm without swapping cylinders.
Adjustable Diverter Arm
Tuning a sorting gate's reach on-site to handle changing package widths without repositioning the entire bracket.
Variable Depth Stacking
Lowering products into bins of varying fill levels by trimming the extend stroke to stop precisely at the current pile height.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X100-50S with the SAUJ32X100-50S
To replace the discontinued SUJ32X100-50S, specify the SAUJ32X100-50S; it is a direct match for the 32 mm bore, 100 mm nominal stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if your end position needs on-site tuning between 50 and 100 mm. Retain the -S magnet option, but note the SAUJ requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the nominal stroke is 100 mm, side-load alignment is generally forgiving, but always verify rod guidance. The stop screw sets end position and does not hold loads; add an external rod lock for vertical or held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X100-50S
- ✓ 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 SUJ32X100-50S FAQ
Yes, the SUJ32X100-50S is discontinued. The direct replacement is the SAUJ32X100-50S, which matches the 32 mm bore, 100 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw allows you to trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 50-100 mm. The stop sets end position only; it is not a load lock.
