This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X160-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X160-75S 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 SUJ50X160-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-75S is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X160-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-75S
The AirTAC SUJ50X160-75S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 85-160 mm extension from the 160 mm nominal maximum. This discontinued 50 mm bore delivers 982 N push and 825 N pull at 0.5 MPa, features a 1/4" port, and mounts via Basic, FA, or LB brackets. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
As the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ50X160-75S, which preserves the bore, stroke, force, and port size. Because this SUJ50X160-75S carries the -S magnet suffix, it used legacy CS1-B/DS1-B switches, whereas the SAUJ successor uses current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 589 N (about 60% of the 982 N push at 0.5 MPa), translating to a vertical lift capacity of about 50 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-75S 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 SAUJ50X160-75S 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 SUJ50X160-75S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning from 85 to 160 mm to accommodate changing material lengths or pitch requirements without swapping the entire actuator.
Adjustable Transfer Pusher
Provides a field-trimmed end position for pushing varying box sizes off a line, using the external stop screw to set the exact ejection distance.
Dynamic Sorting Diverter
Enables quick reconfiguration of the divert stroke length on-site to handle different package depths without reprogramming the machine cycle.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-75S with the SAUJ50X160-75S
To replace the discontinued SUJ50X160-75S, specify the drop-in SAUJ50X160-75S, which retains the 50 mm bore, 160 mm nominal stroke, 75 mm adjust window, and 1/4" port. When sizing both ways, the neighboring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore provides 1559 N push at 0.5 MPa. Select the 75 mm adjust window if your application requires trimming the extend stroke down to a 85 mm minimum; if less adjustability is needed, smaller windows are available. Mounting remains interchangeable via FA and LB brackets (AirTAC SC series compatible only). Because this model has the -S suffix, you must upgrade position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-75S
- ✓ 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 SUJ50X160-75S FAQ
Yes, the SUJ50X160-75S is discontinued. The exact drop-in replacement is the SAUJ50X160-75S, which matches the 50 mm bore, 160 mm stroke, 75 mm adjust window, and 1/4" port. You must upgrade the -S position sensing from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
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 theoretical max of 200 kgf at 1.0 MPa. The external stop screw window is 75 mm, allowing you to trim the 160 mm nominal extend stroke down to a minimum of 85 mm on-site. The stop sets end position and does not lock the load.
