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

About the Airtac SUJ Adjustable Cylinder SUJ100X175-75
The AirTAC SUJ100X175-75 is a double-acting single-rod profile cylinder with an adjustable stroke, allowing you to trim the extend stroke by up to 75 mm on-site for a usable range of 100-175 mm. The external stop screw sets the end position but is not a load lock. This 100 mm bore delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, with a 1/2" port and M20x1.5 rod thread. It uses a compact extruded aluminum profile barrel.
This SUJ model is discontinued and the exact drop-in replacement is the SAUJ100X175-75, matching the bore, stroke, force, port, and FA/LB mounting. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push), yielding a vertical lift capacity of about 200 kg with a 2:1 margin. Note this non-magnetic SKU cannot take a switch. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B, and the stop screw never holds load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-75 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 SAUJ100X175-75 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 SUJ100X175-75 Is Used
Press Fit Tuning
Allows operators to dial in the exact 100-175 mm extend position for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke on-site to accommodate changing package sizes on a packaging line.
Adjustable Stop Gate
Provides a field-tunable end position for pallet stops, letting the 75 mm window adapt to different pallet heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-75 with the SAUJ100X175-75
To replace the discontinued SUJ100X175-75, use the drop-in SAUJ100X175-75, which retains the 100 mm bore, 175 mm nominal stroke, 75 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; choose the 100 mm if you need the 7068 N push at 0.9 MPa. Select the 75 mm adjust window if you need to tune the extend stroke down to 100 mm on-site. Because this is a non-magnetic SKU, it cannot take a switch; the SAUJ upgrade requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits. A plain cylinder drifts on air loss, so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-75
- ✓ 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
