This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X160-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X160-40S 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 SUJ50X160-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-40S 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 SAUJ50X160-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-40S
The AirTAC SUJ50X160-40S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable extend range of 120-160 mm from the 160 mm nominal maximum. The 50 mm bore delivers 982 N push and 825 N pull at 0.5 MPa, rising to 1374 N push at 0.7 MPa. It features a 1/4" port, an M16x1.5 rod thread, and 21 mm adjustable air cushions at each end. This discontinued model is directly replaced by the SAUJ50X160-40S, which matches the bore, stroke, force, port, and FA/LB mounting.
A practical computed insight: the 0.5 MPa push force yields a safe working load of roughly 589 N (60% of 982 N), translating to a vertical lift capacity of about 50 kg with a 2:1 margin. The stop screw sets the end position but is not a load lock; plain cylinders drift on air loss, so use an external rod lock for held loads. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. The SAUJ upgrade retains the compact profile barrel—shorter than an ISO 15552 cylinder of the same bore—and switches to current CMSG/DMSG/EMSG sensors.

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 SAUJ50X160-40S 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 SUJ50X160-40S Is Used
Variable Pitch Push Stations
Adjusting the extend stroke by up to 40 mm on-site allows operators to tune push distance for different product lengths without swapping cylinders.
Diverter Gate Positioning
Trimming the extend stroke on the fly sets the exact gate open width for sorting varying package sizes on a single line.
Packaging Crimp Stops
Fine-tuning the end position by up to 40 mm accommodates different carton depths while maintaining the 982 N push force needed for secure sealing.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-40S with the SAUJ50X160-40S
To replace the discontinued SUJ50X160-40S, order the drop-in SAUJ50X160-40S, which preserves the 50 mm bore, 160 mm nominal stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa, while the 63 mm bore offers 1559 N push at 0.5 MPa; choose based on your exact load. The 40 mm adjust window is ideal if your end-stop varies by up to 40 mm, avoiding the need for a fixed SAU plus an external stop. For the -S magnet option, note that the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-40S
- ✓ 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 SUJ50X160-40S FAQ
Yes, the SUJ50X160-40S is discontinued. The exact drop-in replacement is the SAUJ50X160-40S, which matches the 50 mm bore, 160 mm stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches found on the SUJ.
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 provides a 40 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 120 mm on-site. The stop sets end position only and is not a load lock.
