This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-100, 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 SUJ50X200-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-100 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 SAUJ50X200-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-100
The AirTAC SUJ50X200-100 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, yielding a usable 100-200 mm stroke. It features a 1/4" port, a Ø20 mm rod, and 21 mm adjustable cushions. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ50X200-100, retaining the same bore, stroke, force, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches (this legacy SKU used CS1-B/DS1-B). Because this specific model lacks a magnet, it cannot take a magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-100 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 SAUJ50X200-100 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 SUJ50X200-100 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning from 100 to 200 mm to alter part pitch without swapping cylinders.
Adjustable Reject Diverter
Provides field-adjustable push distance to accommodate changing package widths on a sorting line.
Dynamic Forming Stop
Sets precise carton end positions on the fly, trimming the extend stroke by up to 100 mm for varied box lengths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-100 with the SAUJ50X200-100
To replace the discontinued SUJ50X200-100, specify the direct replacement SAUJ50X200-100, matching the 50 mm bore, 200 mm nominal stroke, and 100 mm adjust window. If migrating, note the SAUJ uses CMSG/DMSG/EMSG sensors whereas the SUJ used CS1-B/DS1-B; this non-magnetic SKU cannot accept a switch anyway. Choose the 100 mm adjust window when you need field-tuning over a wide 100-200 mm range. Mounting uses FA or LB brackets. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The external stop sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-100
- ✓ 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 SUJ50X200-100 FAQ
Yes, the SUJ50X200-100 is discontinued. The direct replacement is the SAUJ50X200-100, offering the same 50 mm bore, 200 mm stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting double-rod cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushing 1374 N at 0.7 MPa and 1767 N at 0.9 MPa. The external stop screw trims the extend stroke by up to 100 mm on-site, giving a usable 100-200 mm stroke. The stop sets end position but is not a load lock.
