This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-30 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 SUJ100X175-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-30 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 SAUJ100X175-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-30
The AirTAC SUJ100X175-30 is a discontinued double-acting single-rod profile cylinder with a 175mm nominal stroke and a 30mm external stop screw window, allowing you to trim the extend stroke on-site down to 145mm. It features a 100mm bore, a 1/2" port, and a 25mm rod. The exact drop-in replacement is the SAUJ100X175-30, which matches the bore, stroke, 30mm adjust window, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. This non-magnetic SKU cannot accept a sensor.
At 0.5MPa it delivers 3927N push and 3681N pull force, peaking at 7068N push at 0.9MPa. A computed buyer insight: the safe working load is roughly 2356N (60% of the 0.5MPa push), yielding a 200kg vertical lift capacity with a 2:1 margin. The external stop screw sets the end position but is not a load lock; the cylinder drifts on air loss, so use an external rod lock for held loads. Its compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-30 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 SAUJ100X175-30 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 SUJ100X175-30 Is Used
Variable Depth Forming Press
Adjusts the extend stroke on-site to control material depth during prototyping, using the 30mm stop window to fine-tune the 7068N push force without re-plumbing the 1/2 inch port.
Adjustable Length Diverters
Tunes the extend position to handle changing package sizes on a line, trimming the 175mm stroke down to 145mm to accommodate narrower items while maintaining compact profile clearance.
Variable Height Lift Stops
Sets precise mechanical end positions for varying pallet heights, relying on the external stop screw for repeatable positioning while requiring an external rod lock to hold the load safely.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-30 with the SAUJ100X175-30
To replace the discontinued SUJ100X175-30, order the SAUJ100X175-30 drop-in: it keeps the 100mm bore, 175mm nominal stroke, 30mm adjust window, 1/2" port, and FA/LB mounting. If sizing both ways, the neighboring 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore provides 3927N. Choose the 30mm adjust window when you need precise field tuning of the extend stroke from 145 to 175mm. Because this is a non-magnetic SKU, it cannot take a switch; the SAUJ -S variant uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes at or above 300mm, verify side-load limits to prevent guide wear. The stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-30
- ✓ 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 SUJ100X175-30 FAQ
Yes, the SUJ100X175-30 is discontinued. The exact drop-in replacement is the SAUJ100X175-30, which matches the 100mm bore, 175mm stroke, 30mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting single-rod 100mm bore provides 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa. The 30mm external stop screw window allows you to trim the 175mm extend stroke down to 145mm on-site. The stop sets end position but is not a load lock.
