This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X225-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X225-30 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 SUJ63X225-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X225-30 is a double-acting profile-type standard cylinder with a Ø63mm bore and 225mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ63X225-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X225-30
The AirTAC SUJ63X225-30 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 195-225 mm extension window from the 225 mm nominal maximum. Because this SUJ model is discontinued, the exact drop-in replacement is the SAUJ63X225-30, which matches the 63 mm bore, 3/8" port, and force characteristics while upgrading sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B.
At 0.5 MPa this 63 mm bore generates 1559 N push and 1402 N pull force, peaking at 2805 N push at 0.9 MPa. A practical computed insight sets the safe working load around 935 N (60% of the 0.5 MPa push), translating to a 79 kg vertical lift with a 2:1 safety margin. The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock for held loads. This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X225-30 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 SAUJ63X225-30 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.

Where the Airtac SUJ Adjustable Cylinder SUJ63X225-30 Is Used
Variable Pitch Indexing
Dialing in the exact 195-225 mm extend position on-site to push parts into a machine without re-mounting the cylinder when product lengths change.
Adjustable Transfer Diverter
Tuning the extend stop to deflect varying package widths on a conveyor line, using the external screw to set the precise 30 mm trim window.
Custom Format Pusher
Setting a specific ejection stroke for mixed-size cartons, adjusting the end position on the fly to avoid crushing lighter items.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X225-30 with the SAUJ63X225-30
To replace the discontinued SUJ63X225-30, specify the SAUJ63X225-30 drop-in: it preserves the 63 mm bore, 225 mm stroke, 30 mm adjust window, 3/8" port, M16x1.5 rod thread, and FA/LB mounting. When sizing both ways, the neighbouring 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N push. Select the 30 mm adjust window if you need on-site extend tuning between 195 and 225 mm; for fixed stops, a standard SAU cylinder is simpler. Because this SKU lacks a magnet, it cannot accept a sensor; if position detection is needed, choose the -S SAUJ variant and pair it with current CMSG/DMSG/EMSG sensors. For this 225 mm stroke, verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X225-30
- ✓ 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 SUJ63X225-30 FAQ
Yes, the SUJ63X225-30 is discontinued. The exact drop-in replacement is the SAUJ63X225-30, which shares the same 63 mm bore, 225 mm stroke, 30 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.
This double-acting single-rod cylinder delivers 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 provides a 30 mm trim window, allowing the extend stroke to be shortened from the 225 mm maximum down to 195 mm on-site. The stop sets end position only; it is not a load lock.
