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

About the Airtac SUJ Adjustable Cylinder SUJ63X100-30S
The AirTAC SUJ63X100-30S is a double-acting double-rod profile cylinder with a 63mm bore and an external stop screw that lets you trim the extend stroke by up to 30mm on-site, yielding a usable 70-100mm stroke from the 100mm nominal maximum. Because it is discontinued, the direct replacement is the SAUJ63X100-30S, which preserves the 3/8" port, M16x1.5 rod thread, and 21mm adjustable cushions.
The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss, so use an external rod lock for held loads. Upgrading to the SAUJ keeps the SC-series FA/LB mounting but moves magnet sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X100-30S 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 SAUJ63X100-30S 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 SUJ63X100-30S Is Used
Variable Stroke Clamping
Allows operators to dial in the exact 70-100mm extend position for clamping parts of mixed lengths without changing fixtures.
Adjustable Diverter Gate
Tunes the extend stop on-site to deflect varying package sizes on a line, providing precise routing without repositioning the cylinder.
Variable Depth Pusher
Trims the extend stroke by up to 30mm to push boxes into different lane depths, accommodating varied pallet patterns dynamically.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X100-30S with the SAUJ63X100-30S
To replace this discontinued SUJ63X100-30S, specify the SAUJ63X100-30S direct: it matches the 63mm bore, 100mm nominal stroke, 30mm adjust window, 3/8" port, and FA/LB mounting. Choose the 30mm adjust window when you need precise 70-100mm extend tuning without shimming. Retain the -S magnet option, but note the SAUJ requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X100-30S
- ✓ 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 SUJ63X100-30S FAQ
Yes, the SUJ63X100-30S is discontinued. The direct replacement is the SAUJ63X100-30S, which matches the 63mm bore, 100mm nominal stroke, 30mm 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 switches.
The external stop screw provides a 30mm adjust window, allowing the extend stroke to be shortened from the 100mm maximum down to 70mm on-site. The stop sets end position and is not a load lock.
