This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-40S, 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 SUJ50X200-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-40S 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 SAUJ50X200-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-40S
The AirTAC SUJ50X200-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 160-200 mm extension out of the 200 mm nominal maximum. This unit is DISCONTINUED; the direct replacement is the SAUJ50X200-40S, retaining the 1/4" port, M16x1.5 rod thread, 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. This SUJ features a piston magnet for legacy CS1-B/DS1-B sensors, whereas the SAUJ successor uses current CMSG/DMSG/EMSG switches. The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-40S 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 SAUJ50X200-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ50X200-40S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×200 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ50X200-40S Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 40 mm to alter part pitch without swapping cylinders.
Adjustable Diverter Gate
Fine-tunes the gate extension distance on-site to accommodate different package widths.
Dynamic End-Stop Positioning
Provides a field-adjustable hard stop for varying product lengths entering a storage lane.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-40S with the SAUJ50X200-40S
To replace the discontinued SUJ50X200-40S, order the direct replacement SAUJ50X200-40S, which matches the 50 mm bore, 200 mm stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. The 40 mm adjust window is ideal if your end-stop varies, beating a fixed SAU plus an external stop. For the -S magnet option, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG on the SAUJ. For this 200 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-40S
- ✓ 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 SUJ50X200-40S FAQ
Yes, the SUJ50X200-40S is discontinued. The direct replacement is the SAUJ50X200-40S, matching the 50 mm bore, 200 mm stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable extension of 160-200 mm. The stop sets end position but is not a load lock.
