This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-100SH, 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 SUJ50X200-100SH
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-100SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X200-100SH, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-100SH
The AirTAC SUJ50X200-100SH is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, giving a usable 100-200 mm extension out of the 200 mm nominal maximum. Equipped with a -S piston magnet for legacy CS1-B/DS1-B switches and a -H Viton seal rated for 0-150 C, it features a 1/4" port, an M16x1.5 rod thread, and 21 mm adjustable cushions.
This SUJ unit is discontinued; the direct replacement is the SAUJ50X200-100SH, matching the bore, stroke, 100 mm adjust window, force, and FA/LB mounting. Upgrading to the SAUJ transitions you to current CMSG/DMSG/EMSG sensors. Note the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-100SH 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 SAUJ50X200-100SH 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 SUJ50X200-100SH Is Used
Variable Pitch Indexing
Allows operators to dial in the extend stroke from 100 to 200 mm on-site to accommodate varying material lengths without swapping the entire actuator.
Adjustable Reject Pusher
Provides a 100 mm trim window to alter the push-off distance for different product sizes on a packaging line, ensuring precise ejection.
Variable Depth Diverter
Enables field adjustment of the diverting stroke up to 200 mm to handle changing pallet depths or lane widths directly at the machine.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-100SH with the SAUJ50X200-100SH
To replace the discontinued SUJ50X200-100SH, order the direct replacement SAUJ50X200-100SH, which preserves the 50 mm bore, 200 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 100 mm adjust window if your fixture needs on-site extend tuning from 100 to 200 mm. Because this model has the -S magnet, you must swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. Remember the stop screw only sets end position; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-100SH
- ✓ 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 SUJ50X200-100SH FAQ
Yes, the AirTAC SUJ50X200-100SH is discontinued. The direct replacement is the SAUJ50X200-100SH, which matches the 50 mm bore, 200 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. You will need to upgrade your -S sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the extend stroke on-site from the 200 mm maximum down to 100 mm. The stop sets end position but is not a load lock.
