This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ40X100-10, 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 SUJ40X100-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X100-10 is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ40X100-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X100-10
The AirTAC SUJ40X100-10 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 90-100 mm extend out of the 100 mm nominal maximum. This compact aluminum-barrel unit delivers 628 N push and 528 N pull at 0.5 MPa, features a 1/4" port, and uses adjustable 21 mm cushions.
Because this SKU lacks a magnet, it cannot take a switch. The exact drop-in replacement is the SAUJ40X100-10, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors (the SUJ used legacy CS1-B/DS1-B) and offers the SAUF built-in-valve variant. For sizing, a safe working load is roughly 377 N (60% of the 628 N push), and vertical lift is about 32 kg with a 2:1 margin. The stop sets end position only; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X100-10 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 SAUJ40X100-10 produces the same force from the same bore — a true drop-in on output. 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 SUJ40X100-10 Is Used
Diverter Gate Adjustment
Trimming the extend stroke by up to 10 mm on-site allows precise positioning of a diverter gate without machining spacer plates.
Package Stopper Tuning
External stop screw fine-tunes the end position of a conveyor lane stopper to accommodate varying carton heights.
Clamp Positioning
Adjustable extend endpoint lets operators dial in the exact clamping position for delicate parts on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X100-10 with the SAUJ40X100-10
To replace the discontinued SUJ40X100-10, use the drop-in SAUJ40X100-10, which preserves the 40 mm bore, 100 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. When sizing both ways, the neighboring 32 mm bore provides 402 N push at 0.5 MPa, while the 50 mm bore offers 982 N push at 0.5 MPa. Choose the 10 mm adjust window if you need minor field tuning of the extend end position; for larger trims, select a model with a wider adjust range. Since this SKU has no magnet, it cannot accept a sensor; if sensing is required, move to an SAUJ-S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For this 100 mm stroke, side-load is minimal, but for strokes >=300 mm, guide the load externally to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X100-10
- ✓ 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 SUJ40X100-10 FAQ
Yes, the SUJ40X100-10 is discontinued. The exact drop-in replacement is the SAUJ40X100-10, which matches the 40 mm bore, 100 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting.
The double-acting single-rod force is 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, 1130 N push at 0.9 MPa, and a theoretical max of 128 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to shorten the extend stroke from the 100 mm nominal maximum down to 90 mm.
