This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X220-20S, 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 SUJ32X220-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X220-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 220mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X220-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X220-20S
The AirTAC SUJ32X220-20S 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 200-220 mm window from the 220 mm nominal maximum. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ32X220-20S, matching the 32 mm bore, force, and FA/LB mounting. The SAUJ upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X220-20S 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 SAUJ32X220-20S 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 SUJ32X220-20S Is Used
Diverter Gate Positioning
Allows field tuning of the extend stroke by up to 20 mm to hit the exact angle on a diverter gate without machining spacers.
Package Stopper Height
Ideal for a conveyor stop where the nominal 220 mm extend is slightly too long and needs a 200-220 mm adjustable end position.
Light Load Ejection
Provides a safe 241 N working load for ejecting light parts, with the 20 mm trim accommodating varying box sizes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X220-20S with the SAUJ32X220-20S
To replace the discontinued SUJ32X220-20S, order the direct replacement SAUJ32X220-20S, which preserves the 32 mm bore, 220 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need on-site extend tuning between 200 and 220 mm; for longer trims, select a larger adjust figure. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. At 220 mm stroke, verify side-load limits, as plain cylinders drift on air loss and the stop screw is not a lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X220-20S
- ✓ 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 SUJ32X220-20S FAQ
Yes, the SUJ32X220-20S is discontinued. The direct replacement is the SAUJ32X220-20S, which matches the 32 mm bore, 220 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the extend stroke from the 220 mm nominal maximum down to 200 mm on-site. The stop sets end position and is not a load lock.
