This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-100S 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 SUJ100X175-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-100S 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 SAUJ100X175-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-100S
The AirTAC SUJ100X175-100S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 75-175 mm stroke. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. This discontinued SUJ model is replaced by the SAUJ100X175-100S.
The SAUJ100X175-100S is a drop-in replacement retaining the exact bore, stroke, force, and port. 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 stop screw sets end position but is not a load lock; use an external rod lock for held loads. The -S magnet used legacy CS1-B/DS1-B sensors, while the SAUJ uses CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-100S 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 SAUJ100X175-100S 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 SUJ100X175-100S Is Used
Variable Depth Forming
A press operation needing precise 75 to 175 mm extend lengths. The external stop screw allows operators to trim the exact pressing depth on-site without swapping cylinders.
Adjustable Transfer Pushers
Packaging lines handling mixed carton sizes use the 100 mm adjust window to alter the push-off distance on the fly, accommodating different box lengths efficiently.
Custom Sorter Positioning
Diverting mechanisms requiring field-tuned end positions to handle varying product widths. The stop screw sets the exact extend endpoint for each shift.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-100S with the SAUJ100X175-100S
To replace the discontinued SUJ100X175-100S, use the SAUJ100X175-100S. It is a drop-in match for bore, stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the 80 mm neighbor bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa. Choose the 100 mm adjust window when you need maximum field flexibility to trim the 175 mm extend stroke down to 75 mm. The -S suffix means a piston magnet is present; you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or more, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-100S
- ✓ 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 SUJ100X175-100S FAQ
Yes, the SUJ100X175-100S is discontinued. The exact drop-in replacement is the SAUJ100X175-100S, which matches the 100 mm bore, 175 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
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 theoretical max is 801 kgf at 1.0 MPa. The external stop screw window is 100 mm, allowing you to shorten the 175 mm nominal extend stroke down to 75 mm on-site. The stop sets end position and is not a load lock.
