This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X100-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X100-20S 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 SUJ63X100-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X100-20S is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ63X100-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X100-20S
The AirTAC SUJ63X100-20S is a discontinued 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 80 to 100 mm stroke. Its extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. At 63 mm, it delivers 1559 N push and 1402 N pull at 0.5 MPa, features a 20 mm rod, M16x1.5 rod thread, and a 3/8" port.
Because the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ63X100-20S, which retains the same force, adjust window, and FA/LB mounting. Upgrading to the SAUJ moves you from the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches. The stop screw sets the end position but is not a load lock; for held loads, add an external rod lock. A computed buyer insight: the safe working load is about 935 N (60% of the 0.5 MPa push), allowing a 79 kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X100-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUJ63X100-20S 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ63X100-20S
| SU | Profile-type standard cylinder (discontinued). |

| 63 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ63X100-20S Is Used
Variable Pitch Indexing
A packaging line that needs to alter the extend reach by up to 20 mm for different carton depths without swapping out the entire cylinder assembly.
Adjustable Diverter Gate
A conveyor sorting station requiring field tuning of the actuation length to handle varying product widths on the fly.
Variable Depth Pusher
A warehousing mechanism that pushes items into shelving, needing a 20 mm stroke reduction to accommodate mixed pallet sizes safely.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X100-20S with the SAUJ63X100-20S
To replace the discontinued SUJ63X100-20S, order the drop-in SAUJ63X100-20S, keeping the 100 mm nominal stroke and 20 mm adjust window. If you need to resize, the neighboring 50 mm bore gives 982 N push at 0.5 MPa, while the 80 mm bore yields 2513 N. Choose the 20 mm adjust window when you need precise field tuning of the extend stroke rather than relying on a fixed SAU plus an external stop. The SAUJ accepts FA and LB mounts, and your -S magnet version requires switching from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify your side-load limits to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X100-20S
- ✓ 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 SUJ63X100-20S FAQ
Yes, the SUJ63X100-20S is discontinued. The exact drop-in replacement is the SAUJ63X100-20S, which matches the 63 mm bore, 100 mm stroke, 20 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The double-acting single-rod 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 2805 N push at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 20 mm on-site, giving a usable stroke range of 80 to 100 mm. The stop sets the end position and is not a load lock.
