This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-20S, 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 SUJ32X300-20S
The AirTAC SUJ Adjustable Cylinder SUJ32X300-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-20S
The AirTAC SUJ32X300-20S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable 280-300 mm stroke. The nominal 300 mm is the maximum. This discontinued model is replaced by the SAUJ32X300-20S.
The direct replacement SAUJ32X300-20S keeps the exact bore, stroke, force, and FA/LB mounting. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrades from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-20S 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 SAUJ32X300-20S 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 SUJ32X300-20S Is Used
Custom Clamping Stops
Allows operators to dial in the exact 280-300 mm extend position for clamping parts of varying widths without reprogramming the PLC.
Variable Depth Drilling
Provides a hard mechanical stop to set precise drilling depths on-site, accommodating different material thicknesses on the fly.
Adjustable Sorting Diverter
Tunes the extend stroke to route different package sizes on a conveyor, ensuring the diverter meets specific product dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-20S with the SAUJ32X300-20S
To replace the discontinued SUJ32X300-20S, order the direct replacement SAUJ32X300-20S, which preserves the 32 mm bore, 300 mm stroke, 20 mm adjust window, and 1/8" port. Choose the 20 mm adjust window if your end-position needs field tuning. Mounting uses FA/LB brackets compatible with the AirTAC SC series. Because the -S suffix denotes a magnet, swap legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. At 300 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-20S
- ✓ 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 SUJ32X300-20S FAQ
Yes, the SUJ32X300-20S is discontinued. The direct replacement is the SAUJ32X300-20S, which shares the same 32 mm bore, 300 mm stroke, 20 mm adjust window, and 1/8" port. The SAUJ also upgrades the sensor compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the extend stroke from the 300 mm maximum down to 280 mm on-site. The stop sets end position and is not a load lock.
