This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-75S 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 SUJ100X175-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-75S 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 SAUJ100X175-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-75S
The AirTAC SUJ100X175-75S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 100-175 mm stroke. The nominal 175 mm is the maximum. It 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 impact. This unit is DISCONTINUED; the exact drop-in replacement is the SAUJ100X175-75S.
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 the end position but is not a load lock; use an external rod lock for held loads. The SAUJ successor keeps the SC-series FA/LB mounting but upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Choosing this adjustable cylinder beats machining external stops on a fixed-stroke SAU when you need field tuning.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-75S 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 SAUJ100X175-75S 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X175-75S

| ×175 | 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 SUJ100X175-75S Is Used
Variable Depth Boring
Trimming the extend stroke by up to 75 mm on-site allows precise depth control for boring operations without swapping the entire cylinder.
Adjustable Diverter Stroke
Field-tuning the 100-175 mm extend window adapts a conveyor diverter arm to different package sizes on the fly.
Custom Crate Pressing
Dialing in the exact extend stop ensures consistent lid pressing force on variable-height crates before fastening.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-75S with the SAUJ100X175-75S
To replace the discontinued SUJ100X175-75S, order the SAUJ100X175-75S; it matches the 100 mm bore, 175 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. When sizing, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Pick the 75 mm adjust window if you need to trim the extend stroke down to 100 mm on-site. Because this -S model has a piston magnet, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-75S
- ✓ 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 SUJ100X175-75S FAQ
Yes, the SUJ100X175-75S is discontinued. The exact drop-in replacement is the SAUJ100X175-75S, which shares the same 100 mm bore, 175 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ upgrades the sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The double-acting single-rod cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and an 801 kgf max at 1.0 MPa. The external stop screw allows trimming the extend stroke by up to 75 mm on-site, giving a usable 100-175 mm stroke. The stop sets end position and is not a load lock.
