This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X150-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X150-50 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 SUJ50X150-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-50 is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X150-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-50
The AirTAC SUJ50X150-50 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 100-150 mm extension from the 150 mm nominal maximum. This discontinued unit delivers 982 N push and 825 N pull at 0.5 MPa, features a 1/4" port, and uses adjustable 21 mm cushions. The stop screw sets the end position but is not a load lock.
You must replace this end-of-life model with the drop-in SAUJ50X150-50, which matches the 50 mm bore, force, port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B switches. As a computed buyer insight, the safe working load is roughly 589 N (60% of the 982 N push), allowing a 50 kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-50 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X150-50 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 SUJ50X150-50 Is Used
Variable Stroke Clamping
Adjusts the extend stroke on-site to clamp parts of varying widths without swapping the entire cylinder.
Variable Position Diverting
Tunes the extend stop to deflect different carton sizes accurately on a packaging line.
Adjustable Depth Stops
Sets precise extend endpoints for multiple pusher locations in material handling racking.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-50 with the SAUJ50X150-50
To replace the discontinued SUJ50X150-50, order the exact drop-in SAUJ50X150-50, which preserves the 50 mm bore, 150 mm nominal stroke, 50 mm adjust window, 1/4" port, and FA/LB mounting. If resizing, the neighbouring 40 mm bore yields 628 N push, while the 63 mm bore yields 1559 N push at 0.5 MPa. Choose the 50 mm adjust window when you need on-site extend tuning from 100 to 150 mm; if you require a fixed 100 mm stroke, a standard SAU cylinder is simpler. Because this SKU has no magnet, you cannot mount sensors; the SAUJ upgrade supports CMSG/DMSG/EMSG switches (replacing the SUJ's CS1-B/DS1-B). For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The stop screw sets end position only; use an external rod lock or pilot-operated check valve to hold loads safely.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-50
- ✓ 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 SUJ50X150-50 FAQ
Yes, the SUJ50X150-50 is discontinued. The exact drop-in replacement is the SAUJ50X150-50, which matches the 50 mm bore, 150 mm stroke, 50 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also upgrades sensor compatibility to CMSG/DMSG/EMSG switches.
The 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and 1767 N push at 0.9 MPa, with a 200 kgf theoretical max at 1.0 MPa. The external stop screw provides a 50 mm adjust window, allowing you to trim the extend stroke from the 150 mm nominal maximum down to 100 mm on-site.
