This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X160-100S, 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 SUJ50X160-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X160-100S is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X160-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X160-100S
The AirTAC SUJ50X160-100S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, giving a usable 60-160 mm range from the 160 mm nominal maximum. This discontinued model is replaced by the SAUJ50X160-100S, a direct upgrade sharing the same bore, stroke, force, port, and FA/LB mounting.
The SAUJ replacement upgrades sensing to current CMSG/DMSG/EMSG switches, whereas this SUJ used legacy CS1-B/DS1-B sensors. The stop screw sets the end position but is not a load lock; drift occurs on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X160-100S 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 SAUJ50X160-100S 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 SUJ50X160-100S Is Used
Variable Pitch Indexing
Allows operators to dial in the extend stroke from 60 to 160 mm on-site to alter part spacing without swapping cylinders.
Adjustable Diverter Gate
Fine-tunes the gate extension distance on the fly to accommodate different package sizes moving down the line.
Variable Depth Pusher
Trims the pusher stroke by up to 100 mm to load cartons of varying depths into palletizing cells.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X160-100S with the SAUJ50X160-100S
To replace the discontinued SUJ50X160-100S, specify the SAUJ50X160-100S, which matches the 50 mm bore, 160 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 100 mm adjust window if your assembly requires field tuning of the extend stroke between 60 and 160 mm. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X160-100S
- ✓ 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 SUJ50X160-100S FAQ
Yes, the SUJ50X160-100S is discontinued. The direct replacement is the SAUJ50X160-100S, which shares the same 50 mm bore, 160 mm stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ upgrades sensing to CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 160 mm nominal maximum down to 60 mm on-site. The stop sets end position but is not a load lock.
