This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X250-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X250-30 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 SUJ100X250-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-30 is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X250-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-30
The AirTAC SUJ100X250-30 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 220-250 mm stroke from the 250 mm nominal maximum. It features a 100 mm bore, a 25 mm rod, M20x1.5 rod threads, and a 1/2 inch port. This bore delivers substantial force: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa.
Because the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ100X250-30, which preserves the bore, stroke, 30 mm adjust window, and mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a vertical lift capacity of about 200 kg with a 2:1 margin. Note this non-magnetic SKU cannot accept a sensor, and the stop screw sets end position only—it is not a load lock.

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 SAUJ100X250-30 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 SUJ100X250-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 220-250 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Trimming the extend stroke by up to 30 mm accommodates different package sizes on a packaging line without swapping cylinders.
Adjustable End Stop
Provides a field-adjustable mechanical end position for pallet lifting or positioning where the exact stopping point varies by product run.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-30 with the SAUJ100X250-30
To replace this discontinued SUJ100X250-30, select the SAUJ100X250-30; it is a true drop-in swap retaining the 100 mm bore, 250 mm nominal stroke, 30 mm adjust window, 1/2 inch port, and SC-series FA/LB mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N push at 0.5 MPa (7068 N at 0.9 MPa). Choose the 30 mm adjust window if your mechanism needs field-tuning the extend stroke down to 220 mm. Because this specific SKU lacks a magnet, it cannot accept position sensors; if sensing is required, move to the SAUJ and specify current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw merely sets the end position; it is not a lock, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-30
- ✓ 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 SUJ100X250-30 FAQ
Yes, the SUJ100X250-30 is discontinued. The exact drop-in replacement is the SAUJ100X250-30, which matches the 100 mm bore, 250 mm stroke, 30 mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This double-acting single-rod cylinder has a 30 mm adjust window, allowing you to shorten the 250 mm extend stroke down to 220 mm. Force output is 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. It uses a 1/2 inch port. The stop screw sets end position only and is not a load lock.
