This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X250-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X250-30S 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 SUJ100X250-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-30S 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 SAUJ100X250-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-30S
The AirTAC SUJ100X250-30S is a discontinued double-acting single-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 220-250 mm window (250 mm nominal maximum). It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The exact drop-in replacement is the SAUJ100X250-30S, matching the 100 mm bore, stroke, force, and SC-series FA/LB mounting.
At 0.5 MPa it delivers 3927 N push and 3681 N pull force, peaking at 7068 N push at 0.9 MPa. A practical safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and adds an SAUF built-in-valve variant. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X250-30S 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 SAUJ100X250-30S 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 SUJ100X250-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 220-250 mm extend position on-site for inserting bearings or pins without re-mounting the cylinder.
Variable Length Diverter
Adjusts the extend stop to deflect different package sizes on a packaging line, providing precise stroke trimming for changing product formats.
Adjustable Height Stopper
Sets a hard mechanical end position for pallets or workpieces, trimming the stroke by up to 30 mm to accommodate varying load dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-30S with the SAUJ100X250-30S
To replace this discontinued SUJ100X250-30S, order the SAUJ100X250-30S drop-in equivalent, keeping the 100 mm bore, 250 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. If resizing, neighbouring bores offer different forces at 0.5 MPa: the 80 mm pushes 2513 N, while the 63 mm pushes 1559 N. Choose the -30 mm adjust window when you need precise 220-250 mm extend tuning on-site; the SAUJ also provides the SAUF built-in-valve variant the SU line lacked. Because this model includes a magnet (-S), migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For this 250 mm stroke, side-load is minimal, but always confirm rod bearing capacity for longer strokes.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-30S
- ✓ 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 SUJ100X250-30S FAQ
Yes, the SUJ100X250-30S is discontinued. The exact drop-in replacement is the SAUJ100X250-30S, matching the 100 mm bore, 250 mm stroke, 30 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.
It 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 (801 kgf theoretical max at 1.0 MPa). The external stop screw window is 30 mm, allowing you to trim the extend stroke from 250 mm down to 220 mm on-site. The stop sets end position only and is not a load lock.
