This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-10S, 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 SUJ40X200-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X200-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-10S
The AirTAC SUJ40X200-10S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable 190-200 mm range from the 200 mm nominal maximum. This SUJ model is discontinued; the direct replacement is the SAUJ40X200-10S, matching the bore, stroke, force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade retains the compact profile barrel but moves to current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X200-10S 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 SUJ40X200-10S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | 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 SUJ40X200-10S Is Used
Diverter Gate Positioning
Needs field stroke tuning to dial in the exact 190-200 mm extend point for a diverter flap without machining hard stops.
Product Reject Arm
Allows on-site stroke trimming to precisely strike passing items on a conveyor at varying lane widths.
Carton Flap Folder
Fine-tunes the extend endpoint to accommodate slight carton size variations on the packaging line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-10S with the SAUJ40X200-10S
To replace the discontinued SUJ40X200-10S, order the direct replacement SAUJ40X200-10S, which keeps the 40 mm bore, 200 mm stroke, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window if you need to fine-tune the extend stroke down to 190 mm on-site. Because this model has the -S magnet, you must switch from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For this 200 mm stroke, verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-10S
- ✓ 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 SUJ40X200-10S FAQ
Yes, the SUJ40X200-10S is discontinued. The direct replacement is the SAUJ40X200-10S, which matches the 40 mm bore, 200 mm stroke, 1/4" 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 offers a 10 mm adjust window, allowing you to shorten the 200 mm extend stroke down to 190 mm on-site. The stop sets end position and is not a load lock.
