This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X190-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X190-50S 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 SUJ100X190-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X190-50S is a double-acting profile-type standard cylinder with a Ø100mm bore and 190mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X190-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X190-50S
The AirTAC SUJ100X190-50S is a discontinued double-acting single-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 140-190 mm range from the 190 mm nominal maximum. The stop sets the end position but is not a load lock. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa, with a 1/2" port and M20x1.5 rod thread.
The exact drop-in replacement is the SAUJ100X190-50S, retaining the bore, stroke, force, port, and FA/LB mounting. A computed buyer 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 upgrades to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches on this -S magnet model. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X190-50S 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 SAUJ100X190-50S 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.

| ×190 | 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 SUJ100X190-50S Is Used
Variable Stroke Clamping
Adjusts the extend position on-site to clamp parts of varying heights without re-engineering fixed stops.
Adjustable Diverter Gate
Tunes the gate extend distance by up to 50 mm to accommodate different package sizes on the fly.
Variable Depth Pusher
Trims the extend stroke to push containers to specific conveyor lanes without swapping the cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X190-50S with the SAUJ100X190-50S
To replace the SUJ100X190-50S, order the drop-in SAUJ100X190-50S, which preserves the 100 mm bore, 190 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the 80 mm neighbor bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa and 7068 N at 0.9 MPa. Choose the 50 mm adjust window if your setup requires trimming the extend stroke by up to 50 mm on-site. For the -S magnet option, the SAUJ uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the 190 mm stroke is under 300 mm, side-load lever arm concerns are minimal. The stop screw sets end position but is not a lock; for load holding without live air, specify an external rod lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X190-50S
- ✓ 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 SUJ100X190-50S FAQ
Yes, the SUJ100X190-50S is discontinued. The exact drop-in replacement is the SAUJ100X190-50S, matching the 100 mm bore, 190 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 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, with a 1/2" port. The external stop screw window is 50 mm, allowing you to trim the extend stroke from the 190 mm nominal maximum down to 140 mm on-site. The stop sets end position but is not a load lock.
