This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X225-10, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 SUJ63X225-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X225-10 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 direct replacement is the SAUJ63X225-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X225-10
The AirTAC SUJ63X225-10 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable extension range of 215-225 mm. The nominal 225 mm stroke represents the maximum travel. It features a 63 mm bore, a 20 mm rod, M16x1.5 rod-end thread, adjustable 21 mm cushions at each end, and a 3/8 inch port. Because this SKU lacks a magnet, it cannot accept a magnetic switch for position sensing.
This unit is replaced by the SAUJ63X225-10, a direct upgrade retaining the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and the SAUJ family adds an SAUF built-in-valve variant the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X225-10 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 SAUJ63X225-10 produces the same force from the same bore. 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 SUJ63X225-10 Is Used
Probe Contact Tuning
Trimming the extend stroke by up to 10 mm on-site to set precise probe contact pressure without machining custom spacers.
Divertor Gate Calibration
Adjusting the extend end position in the field to fine-tune a divertor gate opening for varying package sizes.
End-Stop Positioning
Dialing in the exact 215-225 mm extension limit on a packaging pusher to accommodate minor product length variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X225-10 with the SAUJ63X225-10
To replace the discontinued SUJ63X225-10, order the direct replacement SAUJ63X225-10, which matches the 63 mm bore, 225 mm stroke, 10 mm adjust window, 3/8 inch port, and FA/LB mounting. Choose the 10 mm adjust window if you need precise on-site end-position tuning between 215 and 225 mm. Because this specific SKU has no magnet (-S omitted), it cannot support legacy CS1-B/DS1-B sensors; the SAUJ replacement uses CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, carefully verify side-load limits to prevent rod binding. Note that the external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X225-10
- ✓ 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 SUJ63X225-10 FAQ
Yes, the SUJ63X225-10 is discontinued. The direct replacement is the SAUJ63X225-10, which shares the same 63 mm bore, 225 mm stroke, 10 mm adjust window, 3/8 inch port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting double-rod cylinder has a 10 mm adjust window, allowing the 225 mm extend stroke to be shortened to 215 mm on-site. The external stop screw sets the end position but is not a load lock.
