This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X200-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X200-50 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 SUJ100X200-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X200-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X200-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X200-50
The AirTAC SUJ100X200-50 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 150-200 mm from the 200 mm nominal maximum. The 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, 29 mm adjustable air cushions, and a 1/2" port. This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X200-50, sharing the same bore, stroke, force, port, and FA/LB mounting.
For sizing, the safe working load is roughly 2356 N (about 60% of the 0.5 MPa push force), translating to a 200 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors, whereas this non-magnetic SKU used legacy CS1-B/DS1-B switches and cannot take sensors. Its compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

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 SAUJ100X200-50 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 SUJ100X200-50 Is Used
Variable Stroke Pressing
Ideal for pressing operations where the extend stroke must be fine-tuned on-site by up to 50 mm to accommodate material thickness variations without re-engineering the fixture.
Adjustable Diverter Arms
Perfect for conveyor diverters requiring a 150-200 mm reach that can be dialed in precisely during commissioning to match changing package sizes.
Custom Ejector Stops
Used in ejection systems where the external stop screw sets the exact ejection distance on the fly, allowing rapid adaptation for different product runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X200-50 with the SAUJ100X200-50
To replace the discontinued SUJ100X200-50, order the drop-in SAUJ100X200-50, which matches the 100 mm bore, 200 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; choose the 100 mm if you need the 200 kg vertical lift capacity. The 50 mm adjust window is ideal if your extend stroke needs field tuning between 150 mm and 200 mm, often beating a fixed SAU plus external stop. Since this SKU lacks a magnet (-S), it cannot take sensors; the SAUJ requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X200-50
- ✓ 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 SUJ100X200-50 FAQ
Yes, the SUJ100X200-50 is discontinued. The exact drop-in replacement is the SAUJ100X200-50, offering the same 100 mm bore, 200 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 100 mm bore delivers 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 theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjust window, allowing you to trim the extend stroke from the 200 mm maximum down to 150 mm on-site.
