This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-50, 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 SUJ32X250-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X250-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X250-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-50
The AirTAC SUJ32X250-50 is a double-acting double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable stroke range of 200-250 mm from the 250 mm nominal maximum. The stop screw sets the end position but is not a load lock.
The direct replacement is the SAUJ32X250-50, which matches the bore, stroke, 1/8" port, force, and SC-series FA/LB mounting. Because this non-magnetic SKU lacks a switch, it used legacy CS1-B/DS1-B sensors, whereas the current SAUJ uses CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss, so add an external rod lock for held loads.

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 SAUJ32X250-50 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 SUJ32X250-50 Is Used
Variable Pitch Indexing
Allows operators to fine-tune the extend stroke by up to 50 mm on-site to dial in exact material pitches without swapping the entire cylinder.
Adjustable Diverter Gate
Provides a field-tuned extend stop to alter the gate reach on a packaging line, accommodating different box sizes on the fly.
Variable Depth Pusher
Delivers a customizable push distance for loading parts into containers of varying depths, using the external stop to set the exact end position.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-50 with the SAUJ32X250-50
To replace the discontinued SUJ32X250-50, select the direct replacement SAUJ32X250-50, which preserves the 32 mm bore, 250 mm max stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if you need to trim the extend stroke on-site by up to 50 mm. This non-magnetic SKU cannot take a switch; if you need position sensing on the SAUJ, order the -S version for CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load guidance to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-50
- ✓ 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 SUJ32X250-50 FAQ
Yes, the SUJ32X250-50 is discontinued. The direct replacement is the SAUJ32X250-50, matching the 32 mm bore, 250 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the extend stroke from 250 mm down to 200 mm on-site.
