This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X125-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X125-10 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 SUJ100X125-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X125-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X125-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-10
The AirTAC SUJ100X125-10 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable 115-125 mm stroke out of the 125 mm nominal maximum. It delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa, and features a 1/2" port with a 25 mm rod.
The exact drop-in replacement is the SAUJ100X125-10, which matches the bore, stroke, force, port, and FA/LB mounting. A computed buyer insight: the safe working load is roughly 2356 N (60% of the 0.5 MPa push), allowing a 200 kg vertical lift with a 2:1 margin. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X125-10 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 SAUJ100X125-10 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 SUJ100X125-10 Is Used
Press Fit Tuning
Field-trim the 10 mm extend window to dial in exact press-fit depth for large bearings without machining hard stops.
Divertor End Position
Fine-tune the actuator end-stroke on-site to align heavy package diverters precisely to the adjacent lane.
Pallet Stop Calibration
Adjust the extend stop screw to set precise pallet halt positions on the fly as pallet sizes change on the line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-10 with the SAUJ100X125-10
To replace this discontinued SUJ100X125-10, specify the SAUJ100X125-10 drop-in, keeping the 125 mm nominal stroke and 10 mm adjust window. If sizing both ways, the 80 mm bore neighbor provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. Retain FA or LB mounting and note that this non-magnet SKU cannot take a sensor; the SAUJ uses CMSG/DMSG/EMSG switches. The external stop screw sets end position but is not a lock—use an external rod lock for held loads. For strokes >=300, verify side-load limits.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X125-10
- ✓ 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 SUJ100X125-10 FAQ
Yes, the SUJ100X125-10 is discontinued. The exact drop-in replacement is the SAUJ100X125-10, matching the 100 mm bore, 125 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B.
The double-acting single-rod cylinder pushes 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa (max 801 kgf at 1.0 MPa), with 3681 N pull at 0.5 MPa. The external stop screw provides a 10 mm adjust window, making the usable extend stroke 115-125 mm. The stop sets end position and is not a load lock.
