This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X100-20S, 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 SUJ100X100-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X100-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-20S
The AirTAC SUJ100X100-20S is a discontinued 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, yielding a usable 80 to 100 mm stroke. The direct replacement is the SAUJ100X100-20S, matching the bore, force, and mounting.
The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. Equipped with a piston magnet (-S), this unit originally used legacy CS1-B/DS1-B switches, whereas the current SAUJ replacement utilizes CMSG/DMSG/EMSG sensors. Remember that the stop screw sets the 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 SAUJ100X100-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X100-20S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×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 SUJ100X100-20S Is Used
Press Fit Tuning
Allows operators to dial in the exact 80 to 100 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke by up to 20 mm to accommodate different package sizes on a packaging line diverter arm.
Adjustable End Stop
Provides a field-tunable end position for lifting varying pallet heights where a fixed 100 mm stroke would overshoot.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-20S with the SAUJ100X100-20S
To replace the discontinued SUJ100X100-20S, order the direct replacement SAUJ100X100-20S, which preserves the 100 mm bore, 100 mm nominal stroke, 20 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 20 mm adjust window if you need precise on-site end-position tuning between 80 and 100 mm. Because this is an -S model, you must upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, carefully verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-20S
- ✓ 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 SUJ100X100-20S FAQ
Yes, the SUJ100X100-20S is discontinued. The direct replacement is the SAUJ100X100-20S, which matches the 100 mm bore, 100 mm stroke, 20 mm adjust window, 1/2 inch port, and FA/LB mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The double-acting double-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 20 mm adjust window, allowing you to trim the extend stroke from the 100 mm maximum down to 80 mm. The stop sets end position and is not a load lock.
