This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X225-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X225-20 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 SUJ100X225-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-20 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 SAUJ100X225-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-20
The AirTAC SUJ100X225-20 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable 205-225 mm extend window from the 225 mm nominal maximum. As this SUJ series is discontinued, the exact drop-in replacement is the SAUJ100X225-20, retaining the 100 mm bore, 1/2" port, and 29 mm adjustable air cushions.
Force output is substantial: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. 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. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, whereas this non-magnetic SKU used legacy CS1-B/DS1-B switches and cannot hold a load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-20 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 SAUJ100X225-20 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 SUJ100X225-20 Is Used
Press Fit Tuning
Adjust the 20 mm stop screw to set precise lower dead center for press fits, avoiding mechanical shims on varying material thicknesses.
Transfer Diverter
Dial in the extend stroke on-site to accommodate different package widths without repositioning the cylinder's FA or LB mounts.
Carton Sealing Head
Trim the extend travel to match fluctuating carton heights, ensuring consistent sealing pressure across varied production runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-20 with the SAUJ100X225-20
To replace the discontinued SUJ100X225-20, order the drop-in SAUJ100X225-20; it matches the 100 mm bore, 225 mm stroke, 20 mm adjust window, M20x1.5 rod thread, and SC-series FA/LB mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. Select the 20 mm adjust window if you need precise end-position tuning between 205-225 mm. Because this SKU lacks a magnet (-S), it cannot take a switch; the SAUJ uses CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load constraints to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-20
- ✓ 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 SUJ100X225-20 FAQ
Yes, the SUJ100X225-20 is discontinued. The exact drop-in replacement is the SAUJ100X225-20, which matches the 100 mm bore, 225 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting single-rod SUJ100X225-20 delivers 3927 N push / 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The external stop screw provides a 20 mm adjust window, allowing the extend stroke to be shortened from 225 mm down to 205 mm. The stop sets end position but is not a load lock; use an external rod lock for held loads.
