This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X160-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X160-20S 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 SUJ100X160-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X160-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 160mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X160-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X160-20S
The AirTAC SUJ100X160-20S 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, yielding a usable 140-160 mm extend out of the 160 mm nominal maximum. The stop screw sets the end position; it is not a load lock, and a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa, with a 1/2" port and M20x1.5 rod thread.
This SUJ model is discontinued; the exact drop-in replacement is the SAUJ100X160-20S, matching the bore, stroke, force, port and SC-series FA/LB mounting. The -S suffix denotes a piston magnet for position sensing; this legacy cylinder used CS1-B/DS1-B switches, whereas the current SAUJ uses CMSG/DMSG/EMSG sensors. For sizing, the 3927 N push at 0.5 MPa implies a safe working load around 2356 N (60% factor) or a 200 kg vertical lift with a 2:1 margin. The profile barrel is shorter than an ISO 15552 cylinder of the same bore.

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 SAUJ100X160-20S 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 SUJ100X160-20S Is Used
Press Fit Tuning
Adjusting the extend end position on-site to set precise pressing force without machining custom spacers for each batch.
Variable Length Diverter
Trimming the actuator stroke by up to 20 mm to deflect varying package sizes accurately on a packaging line.
Adjustable End Stop
Setting a hard mechanical end position for pallet stops that occasionally requires slight repositioning without re-plumbing.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X160-20S with the SAUJ100X160-20S
To replace the discontinued SUJ100X160-20S, specify the SAUJ100X160-20S; it is a drop-in match for the 100 mm bore, 160 mm stroke, 20 mm adjust window, 1/2" port and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N push at 0.5 MPa and 7068 N at 0.9 MPa. Choose the 20 mm adjust window if you need field tuning of the extend end position; the stop screw shortens stroke on-site but does not lock the load. Retain the -S magnet option but switch legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X160-20S
- ✓ 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 SUJ100X160-20S FAQ
Yes, the SUJ100X160-20S is discontinued. The exact drop-in replacement is the SAUJ100X160-20S, which shares the same 100 mm bore, 160 mm stroke, 20 mm adjust window, 1/2" port and FA/LB mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw offers a 20 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 140 mm on-site. The stop sets end position and is not a load lock.
