This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X450-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X450-100 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 SUJ63X450-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X450-100 is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ63X450-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X450-100
The AirTAC SUJ63X450-100 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 350-450 mm extension from the 450 mm nominal maximum. The 63 mm bore delivers 1559 N push and 1402 N pull at 0.5 MPa, rising to 2805 N push at 0.9 MPa. It features a 20 mm rod, M16x1.5 rod thread, and a 3/8" port.
This SUJ model is discontinued and the direct drop-in replacement is the SAUJ63X450-100, which retains the exact bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 935 N (60% of the 0.5 MPa push), translating to a 79 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X450-100 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 SAUJ63X450-100 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 SUJ63X450-100 Is Used
Variable-Length Ejector
Tuning the extend stroke on-site by up to 100 mm allows an ejection arm to adapt to changing material lengths without swapping cylinders.
Adjustable Transfer Stop
A 350-450 mm extend window provides a field-adjustable physical stop for diverting varying package sizes on a conveyor line.
Dynamic Positioning Pusher
Trimming the stroke precisely positions items into fixtures, accommodating different pallet depths directly on the factory floor.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X450-100 with the SAUJ63X450-100
To replace the discontinued SUJ63X450-100, order the drop-in SAUJ63X450-100, matching the 63 mm bore, 450 mm stroke, 100 mm adjust window, and 3/8" port. If migrating sensors, note that legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG series on the SAUJ body. For force scaling, the neighbouring 50 mm bore provides 982 N push at 0.5 MPa, while the 80 mm bore yields 2513 N; choose based on your exact load. The 100 mm adjust window is ideal when final end positions vary by up to 100 mm, often beating a fixed SAU plus external stop. Because the 450 mm stroke is long, ensure external guides to prevent rod bending and side-load wear. Mounting uses FA or LB brackets compatible with the AirTAC SC series.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X450-100
- ✓ 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 SUJ63X450-100 FAQ
Yes, the AirTAC SUJ63X450-100 is discontinued. The exact drop-in replacement is the SAUJ63X450-100, which matches the 63 mm bore, 450 mm stroke, 100 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.
This double-acting single-rod cylinder has a 100 mm adjust window (usable extend 350-450 mm). Forces are: 1559 N push / 1402 N pull @0.5 MPa; 2182 N push @0.7 MPa; 2805 N push @0.9 MPa; and 318 kgf max @1.0 MPa. The external stop sets end position but is not a load lock; use an external rod lock for held loads.
