This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X100-30SN — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X100-30SN 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 SUJ50X100-30SN
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-30SN is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X100-30SN, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-30SN
The AirTAC SUJ50X100-30SN is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 70-100 mm extension out of the 100 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 NBR seals rated for -20 to +70 C. The stop screw strictly sets the end position; it is not a load lock, so external rod locks are required for held loads.
The direct drop-in replacement is the SAUJ50X100-30SN, retaining the exact bore, force, 1/4" port, and FA/LB mounting. Upgrading to the SAUJ transitions your -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 589 N (60% of the 0.5 MPa push), translating to a 50 kg vertical lift with a 2:1 margin. The SAUJ also introduces the SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-30SN 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 SAUJ50X100-30SN 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 SUJ50X100-30SN Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 30 mm on-site to push parts of varying lengths into a machining station without swapping cylinders.
Adjustable Diverter Gate
Setting a precise 70 to 100 mm extension to deflect different package sizes on a conveyor line, allowing rapid format changes.
Variable Depth Stacking
Trimming the extend stroke on-site to drop items at specific heights into pallets, accommodating varying product profiles.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-30SN with the SAUJ50X100-30SN
To replace the discontinued SUJ50X100-30SN, order the SAUJ50X100-30SN for a direct drop-in swap preserving the 50 mm bore, 100 mm nominal stroke, 30 mm adjust window, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore yields 1559 N push at 0.5 MPa. Choose the 30 mm adjust window if you need field tuning between 70 and 100 mm; if a shorter fixed stroke suffices, a standard SAU avoids the external stop. Retain your FA or LB mounts, but note the -S sensor change: legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-30SN
- ✓ 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 SUJ50X100-30SN FAQ
Yes, the SUJ50X100-30SN is discontinued. The exact drop-in replacement is the SAUJ50X100-30SN, which matches the 50 mm bore, 100 mm nominal stroke, 30 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.
The 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, 1767 N push at 0.9 MPa, and a theoretical max of 200 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable extension range of 70-100 mm. The stop sets end position only; it is not a load lock.
