This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-30H, 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 SUJ50X100-30H
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-30H is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X100-30H, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-30H
The AirTAC SUJ50X100-30H is a double-acting double-rod profile cylinder with a 50 mm bore and a 100 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 70-100 mm stroke window. This discontinued unit carries a -H Viton seal for 0 to 150 C high-temperature environments. The 1/4" port and M16x1.5 rod end are fixed by the bore. Note this SKU lacks a magnet, so it cannot take a magnetic switch. The stop screw sets the end position; it is not a load lock, and a plain cylinder drifts on air loss.
The direct replacement is the SAUJ50X100-30H, matching the bore, stroke, 30 mm adjust window, force, and SC-series FA/LB mounting. Upgrading to the SAUJ is required for current CMSG/DMSG/EMSG sensors, as this legacy model used CS1-B/DS1-B. Theoretical max force is 200 kgf at 1.0 MPa.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-30H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X100-30H 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 SUJ50X100-30H Is Used
Heat Chamber Ejector
Deploying the -H Viton seal in a 150 C oven to eject parts, trimming the 30 mm adjust screw to vary the extend reach precisely for different tooling depths.
Variable Length Diverter
Tuning the extend stroke on-site between 70 and 100 mm to actuate a routing gate for mixed package sizes without swapping out the entire cylinder.
Adjustable Stop Positioner
Setting a hard external mechanical end position for a pallet stop, allowing operators to shorten the stroke by up to 30 mm to accommodate varying load widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-30H with the SAUJ50X100-30H
To replace the discontinued SUJ50X100-30H, order the direct replacement SAUJ50X100-30H; the 50 mm bore, 100 mm max stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting remain identical. Choose the 30 mm adjust window when you need precise 70-100 mm extend tuning on-site, which often beats installing a fixed-stroke cylinder with an external stop. Because this SKU has no magnet, you cannot mount sensors; if sensing is needed, use the SAUJ with CMSG/DMSG/EMSG switches (replacing legacy CS1-B/DS1-B). For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The -H Viton seal allows 0-150 C operation. For load holding, add an external rod lock or pilot-operated check valve, as the adjustable stop and air cushions only decelerate; they do not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-30H
- ✓ 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 SUJ50X100-30H FAQ
Yes, the AirTAC SUJ50X100-30H is discontinued. The direct replacement is the SAUJ50X100-30H, which matches the 50 mm bore, 100 mm max stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable 70-100 mm stroke window. The stop sets end position but is not a load lock.
