This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X100-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X100-75S 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 SUJ50X100-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-75S is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X100-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-75S
The AirTAC SUJ50X100-75S 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 25-100 mm extension window from the 100 mm nominal maximum. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This bore delivers 982 N push and 825 N pull at 0.5 MPa, rising to 1374 N push at 0.7 MPa, with a 1/4" port and M16x1.5 rod thread.
This SUJ50X100-75S model is discontinued; the exact drop-in replacement is the SAUJ50X100-75S, matching the bore, stroke, force, port, and FA/LB mounting. For sizing, a safe working load is roughly 589 N (60% of the 0.5 MPa push), translating to a 50 kg vertical lift with a 2:1 margin. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, which must change to current CMSG/DMSG/EMSG switches on the SAUJ. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-75S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X100-75S 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.

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 SUJ50X100-75S Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 75 mm on-site allows precise depth control for drilling operations without swapping the entire cylinder.
Adjustable Diverter Arms
Field-tuning the 25-100 mm stroke window lets operators reposition diverter arms on a conveyor to handle changing package sizes quickly.
Variable Stroke Pressing
The external stop screw provides repeatable pressing force at varying material thicknesses, setting the exact end position for packaging tasks.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-75S with the SAUJ50X100-75S
To replace the discontinued SUJ50X100-75S, specify the SAUJ50X100-75S drop-in, which preserves the 50 mm bore, 100 mm nominal stroke, 1/4" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore yields 1559 N, compared to this 50 mm bore's 982 N. Choose the 75 mm adjust window if your application requires significant on-site extend trimming down to a 25 mm effective stroke. The -S magnet means you must upgrade from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. Remember the stop screw only sets end position; it does not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-75S
- ✓ 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 SUJ50X100-75S FAQ
Yes, the SUJ50X100-75S is discontinued. The exact drop-in replacement is the SAUJ50X100-75S, which matches the 50 mm bore, 100 mm nominal stroke, 1/4" port, and FA/LB mounting. You must upgrade the -S piston magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and 1767 N push at 0.9 MPa. The external stop screw window is 75 mm, allowing you to trim the 100 mm nominal extend stroke down to a 25 mm effective stroke on-site. The stop sets end position only and is not a load lock.
