This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-30S 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 SUJ100X225-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X225-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-30S
The AirTAC SUJ100X225-30S is a double-acting single-rod adjustable-stroke profile cylinder, now discontinued. It features a 100mm bore, 1/2" port, and a 225mm nominal stroke that you can trim by up to 30mm on-site via an external stop screw, yielding a usable extend range of 195-225mm. The stop screw sets the end position but is not a load lock. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore. The exact drop-in replacement is the SAUJ100X225-30S, matching the bore, stroke, force, port, and FA/LB mounting.
Force output is substantial: push 3927N and pull 3681N at 0.5MPa, push 5497N at 0.7MPa, and push 7068N at 0.9MPa. A computed buyer insight for sizing: the safe working load is roughly 2356N (60% of the 0.5MPa push), translating to a vertical lift capacity of about 200kg with a 2:1 margin. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAUJ replacement transitions to current CMSG/DMSG/EMSG sensors. Note that a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-30S 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 SAUJ100X225-30S 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.

Where the Airtac SUJ Adjustable Cylinder SUJ100X225-30S Is Used
Press Fit Tuning
Adjusting the extend stroke on-site by up to 30mm allows operators to dial in the exact seating depth for bearings or pins without changing the entire cylinder setup.
Variable Length Diverter
Trimming the extend stroke from 225mm down to 195mm accommodates different package sizes on a packaging line, providing flexible sorting without mechanical rebuilds.
Adjustable End Stop
Setting a precise end position between 195mm and 225mm is ideal for palletizing tasks where the load height varies and a hard mechanical stop is required at different lengths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-30S with the SAUJ100X225-30S
To replace the discontinued SUJ100X225-30S, order the drop-in SAUJ100X225-30S, which retains the 100mm bore, 225mm stroke, 30mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore provides 3927N at 0.5MPa or 5497N at 0.7MPa. Choose the 30mm adjust window when you need precise on-site extend tuning between 195-225mm, which often beats installing a fixed-stroke cylinder with an external stop. If your stroke is 300mm or longer, verify side-load limits to prevent rod binding. The -S magnet upgrade requires switching from legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches on the SAUJ.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-30S
- ✓ 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 SUJ100X225-30S FAQ
Yes, the AirTAC SUJ100X225-30S is discontinued. The exact drop-in replacement is the SAUJ100X225-30S. It matches the 100mm bore, 225mm nominal stroke, 30mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The 100mm bore provides 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa. The external stop screw allows you to trim the extend stroke by up to 30mm on-site, giving a usable range of 195-225mm. The stop sets end position and is not a load lock.
