This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-40S, 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 SUJ40X200-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-40S 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 SAUJ40X200-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-40S
The AirTAC SUJ40X200-40S 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 from the 200 mm nominal maximum. The extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
This SUJ40X200-40S model is discontinued and the direct replacement is the SAUJ40X200-40S, which preserves the bore, stroke, force, port, and FA/LB mounting. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUJ successor upgrades to current CMSG/DMSG/EMSG sensors. Note that the external stop sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-40S 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 SAUJ40X200-40S 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 SUJ40X200-40S Is Used
Variable Pitch Indexing
Dialing the extend stroke on-site by up to 40 mm allows a single assembly station to push parts at varying pitches without swapping out the entire cylinder body.
Adjustable Transfer Pusher
Trimming the extend stroke lets operators fine-tune where a product stops on the belt, accommodating different package widths on the fly.
Variable Depth Sealing
The external stop screw precisely sets the extend end position for sealing heads, enabling quick depth changes for varied container heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-40S with the SAUJ40X200-40S
To replace the discontinued SUJ40X200-40S, specify the SAUJ40X200-40S as a direct, keeping the 40 mm bore, 200 mm nominal stroke, 1/4" port, and FA/LB mounting. The 40 mm adjust window is ideal if your end-stop needs on-site tuning between 160 mm and 200 mm, which often beats installing a fixed-stroke SAU plus an external stop. Because this is an -S model, you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For this 200 mm stroke, side-load is minimal, but for any stroke >=300 mm ensure your SC-series mounting guides the load to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-40S
- ✓ 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 SUJ40X200-40S FAQ
Yes, the SUJ40X200-40S is discontinued. You will need to upgrade the -S magnet switches from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the 200 mm nominal extend stroke down to 160 mm on-site. The stop sets end position but is not a load lock.
