This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X150-100SH, 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 SUJ50X150-100SH
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-100SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X150-100SH, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-100SH
The AirTAC SUJ50X150-100SH is a double-acting double-rod profile cylinder with a 50 mm bore and a 150 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 50-150 mm window. It is discontinued; the direct replacement is the SAUJ50X150-100SH, matching the 1/4" port, M16x1.5 rod thread, and 21 mm cushions. The -H suffix specifies a Viton/FKM seal for 0-150 C high-temperature environments.
The -S magnet supports legacy CS1-B/DS1-B switches, whereas the SAUJ replacement uses current CMSG/DMSG/EMSG sensors. Remember the stop screw sets end position but is not a load lock; use an external rod lock for held loads. 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 SAUJ50X150-100SH 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 SAUJ50X150-100SH 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 SUJ50X150-100SH Is Used
Welding Head Positioning
Dial in the exact extend distance on a welding fixture by trimming up to 100 mm on-site, accommodating varying material thicknesses without changing the cylinder.
Variable Depth Clamping
Adjust the clamping reach from 50 to 150 mm to secure different part profiles on the same fixture, using the external stop screw to set the definitive end position.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-100SH with the SAUJ50X150-100SH
To replace the discontinued SUJ50X150-100SH, order the direct replacement SAUJ50X150-100SH, which retains the 50 mm bore, 150 mm max stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 100 mm adjust window when you need precise field tuning of the extend stroke from 50 to 150 mm. The -S sensor upgrade path moves from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The -H Viton seal allows operation up to 150 C.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-100SH
- ✓ 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 SUJ50X150-100SH FAQ
Yes, the SUJ50X150-100SH is discontinued. The direct replacement is the SAUJ50X150-100SH. It matches the 50 mm bore, 150 mm max stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also offers the SAUF built-in-valve variant the SU line lacked.
The external stop screw provides a 100 mm adjustment window, allowing you to shorten the 150 mm nominal extend stroke down to 50 mm on-site. The stop sets end position but is not a load lock.
