This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-20S in place of this model. 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 SUJ100X175-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X175-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-20S
The AirTAC SUJ100X175-20S is a double-acting single-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 155-175 mm extend range from the 175 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa. The 1/2" port and M20x1.5 rod end handle high flow, while the 29 mm adjustable cushions absorb heavy end-of-travel kinetic energy.
This SUJ unit is discontinued; the exact drop-in replacement is the SAUJ100X175-20S, retaining the same bore, stroke, force, and SC-series FA/LB mounting. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors; the SAUJ successor upgrades to current CMSG/DMSG/EMSG switches. Note the stop screw sets end position only—it is not a load lock, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-20S 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 SAUJ100X175-20S produces the same force from the same bore — a true drop-in on output. 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 SUJ100X175-20S Is Used
Press Fit Tuning
Allows operators to dial in the exact 155-175 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 sorting line without swapping cylinders.
Pallet Stop Calibration
Fine-tunes the end position to align pallets precisely against a fixture, compensating for minor mechanical drift over time.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-20S with the SAUJ100X175-20S
To replace the discontinued SUJ100X175-20S, order the SAUJ100X175-20S; it is a true drop-in match for bore, stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N; choose the 100 mm if your safe working load approaches 2356 N. Select the 20 mm adjust window if your mechanism needs field tuning of the extend end position within a 155-175 mm range. Because this model has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUJ. For stroke lengths of 300 mm or greater, verify your side-load limits to prevent guide wear. The stop screw trims stroke but does not lock the load—specify an external rod lock for vertical or held-load safety.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-20S
- ✓ 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 SUJ100X175-20S FAQ
Yes, the AirTAC SUJ100X175-20S is discontinued. The exact drop-in replacement is the SAUJ100X175-20S. It matches the 100 mm bore, 175 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The external stop screw offers a 20 mm adjust window, shortening the extend stroke from the 175 mm maximum down to 155 mm. The stop sets end position but is not a load lock.
