This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X100-30, 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 SUJ63X100-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X100-30 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 direct replacement is the SAUJ63X100-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X100-30
The AirTAC SUJ63X100-30 is a double-acting double-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 70-100 mm extend out of the 100 mm nominal maximum. Because this SUJ model is discontinued, the direct replacement is the SAUJ63X100-30, matching the 63 mm bore, 3/8" port, M16x1.5 rod thread, and 21 mm cushions.
The SAUJ upgrade retains the compact profile barrel and FA/LB mounting but moves to current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B units. Note that this non-magnet SKU cannot take a switch, and the stop screw sets end position without locking the load.

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 SAUJ63X100-30 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 SUJ63X100-30 Is Used
Variable Pitch Indexing
Allows operators to dial in the extend stroke by up to 30 mm on-site to accommodate different material thicknesses or pitch lengths without swapping the entire cylinder.
Adjustable Diverter Gate
Provides a 70 to 100 mm extend range to deflect varying package sizes on a line, using the external stop screw to set the exact gate open position.
Variable Depth Pusher
Enables a pusher arm to handle multiple carton depths by trimming the extend stroke on the fly, ensuring items land precisely on the conveyor lane.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X100-30 with the SAUJ63X100-30
To replace the discontinued SUJ63X100-30, order the direct replacement SAUJ63X100-30, which preserves the 3/8" port, 100 mm nominal stroke, and 30 mm adjust window. Choose the 30 mm adjust window if you need on-site extend tuning between 70 and 100 mm. Mounting is compatible with AirTAC SC series FA and LB brackets. Because this SKU lacks a magnet, it cannot accept a sensor; if sensing is required, specify an -S SAUJ and migrate to CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw only sets the end position; it is not a lock, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X100-30
- ✓ 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 SUJ63X100-30 FAQ
Yes, the SUJ63X100-30 is discontinued. The direct replacement is the SAUJ63X100-30, which matches the 63 mm bore, 100 mm stroke, 30 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.
The external stop screw provides a 30 mm adjust window, allowing the extend stroke to be trimmed from the 100 mm nominal maximum down to 70 mm on-site.
