This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X175-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X175-50 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 SUJ100X175-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-50 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 SAUJ100X175-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-50
The AirTAC SUJ100X175-50 is a double-acting single-rod profile cylinder with an adjustable stroke, allowing you to trim the extend stroke by up to 50 mm on-site. This yields a usable extend range of 125-175 mm from the 175 mm nominal maximum. The 100 mm bore features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions. This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X175-50, matching the bore, stroke, force, and SC-series mounting.
At 0.5 MPa it delivers 3927 N push and 3681 N pull, rising to 7068 N push at 0.9 MPa. A practical computed insight: the 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 SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note this non-magnet SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-50 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 SAUJ100X175-50 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 SUJ100X175-50 Is Used
Variable Stroke Pressing
Dialing in the exact 125-175 mm extend position on-site lets operators set precise contact heights for pressing bearings without machining custom spacers.
Adjustable Diverter Arms
Trimming the extend stroke by up to 50 mm allows a diverter gate to accommodate different package widths on the fly without repositioning the cylinder.
Custom End-Stop Positioning
Setting a specific mechanical end position via the external screw provides a hard, repeatable physical stop for stacking or locating pallets.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-50 with the SAUJ100X175-50
To replace the discontinued SUJ100X175-50, order the drop-in SAUJ100X175-50, which preserves the 175 mm nominal stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. If sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. Choose the 50 mm adjust window when you need precise 125-175 mm extend tuning on-site; a fixed SAU plus external stop is bulkier. Because this SKU lacks a magnet, it cannot accept sensors; the SAUJ -S variant uses CMSG/DMSG/EMSG switches. For stroke lengths of 300 mm or more, verify side-load limits. The stop screw sets end position but is not a lock—use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-50
- ✓ 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 SUJ100X175-50 FAQ
Yes, the SUJ100X175-50 is discontinued. The exact drop-in replacement is the SAUJ100X175-50. It matches the 100 mm bore, 175 mm stroke, 50 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.
The double-acting single-rod 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 window is 50 mm, shortening the 175 mm nominal extend stroke down to 125 mm. The stop sets end position only and does not hold the load on air loss.
