This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X40-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X40-30 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 SUJ63X40-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X40-30 is a double-acting profile-type standard cylinder with a Ø63mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ63X40-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X40-30
The AirTAC SUJ63X40-30 is a double-acting single-rod profile cylinder with a 63mm bore and 40mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 10-40mm stroke window. This discontinued unit delivers 1559N push and 1402N pull at 0.5MPa, features a 20mm rod, M16x1.5 rod thread, and a fixed 3/8" port. The stop sets the end position but is not a load lock.
The exact drop-in replacement is the SAUJ63X40-30, retaining the same bore, stroke, force, port, and SC-series FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. For sizing, a safe working load is roughly 935N (60% of the 0.5MPa push), equating to a 79kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch; load holding requires an external rod lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X40-30 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 SAUJ63X40-30 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 SUJ63X40-30 Is Used
Short-Stroke Clamping
Trimming the extend stroke by up to 30mm on-site allows precise clamping of varying part thicknesses without swapping the entire actuator.
Variable Diverter Gate
Tuning the extend stop on the fly sets the exact gate open angle to route different package sizes down the line.
Adjustable Press Head
Dialing in the 10-40mm stroke window provides accurate downward travel for sealing or light pressing tasks on mixed product runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X40-30 with the SAUJ63X40-30
To replace the discontinued SUJ63X40-30, order the drop-in SAUJ63X40-30. If you need to resize, the neighbouring 50mm bore gives 982N push @0.5MPa, while the 80mm bore gives 2513N push @0.5MPa. Choose the 30mm adjust window if you need to trim the 40mm extend stroke down to a 10mm minimum on-site; the SAUJ beats a fixed cylinder plus external stop by integrating the screw. Mounting uses FA/LB brackets. Since this SKU lacks the -S suffix, it cannot take a magnetic switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For any stroke over 300mm, confirm side-load tolerance. A plain cylinder drifts on air loss, so fit an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X40-30
- ✓ 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 SUJ63X40-30 FAQ
Yes, the SUJ63X40-30 is discontinued. The exact drop-in replacement is the SAUJ63X40-30, matching the 63mm bore, 40mm stroke, 3/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 63mm bore single-rod cylinder pushes 1559N and pulls 1402N at 0.5MPa. Push is 2182N at 0.7MPa and 2805N at 0.9MPa, with a 318kgf max at 1.0MPa. The external stop screw trims the 40mm nominal extend stroke by up to 30mm, giving a 10-40mm usable window. The stop sets end position and is not a load lock.
