This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-40S 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 SUJ100X175-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-40S 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 SAUJ100X175-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-40S
The AirTAC SUJ100X175-40S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 135-175 mm extend window from the 175 mm nominal maximum. The 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 SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X175-40S, which retains the bore, stroke, force, and mounting.
For sizing, the safe working load is roughly 2356 N (about 60% of the 0.5 MPa push force), translating to a 200 kg vertical lift with a 2:1 safety margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade keeps the compact profile and FA/LB mounts but switches the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-40S 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 SAUJ100X175-40S 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 SUJ100X175-40S Is Used
Variable Stroke Pressing
Allows operators to dial in the exact extend stop for pressing bearings or pins where material thickness varies, trimming up to 40 mm without changing the cylinder.
Adjustable Diverter Arms
Provides field-tuned extend positions for routing different package sizes on a line, using the external stop to set the precise reach needed for each format.
End-of-Line Stops
Sets a physical end stop for pallets or trays moving into a test cell, letting maintenance shorten the stroke by up to 40 mm if the cell layout changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-40S with the SAUJ100X175-40S
To replace the discontinued SUJ100X175-40S, order the SAUJ100X175-40S for an exact drop-in match in bore, stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at 0.5 MPa. Choose the 40 mm adjust window if your fixture needs field tuning of the extend stroke; the stop screw sets the end position but does not lock the load. Because this is an -S model, you must upgrade the piston magnet sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-40S
- ✓ 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 SUJ100X175-40S FAQ
Yes, the SUJ100X175-40S is discontinued. The exact drop-in replacement is the SAUJ100X175-40S. It matches the 100 mm bore, 175 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 100 mm bore delivers 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, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 40 mm adjust window, shortening the extend stroke from the 175 mm maximum down to 135 mm. The stop sets end position only; it is not a load lock.
