This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-100, 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 SUJ40X160-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-100 is a double-acting profile-type standard cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X160-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-100
The AirTAC SUJ40X160-100 is a double-acting double-rod profile cylinder with an adjustable stroke, now discontinued. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 60-160 mm extension from the 160 mm nominal maximum. The stop sets the end position but is not a load lock.
The direct replacement is the SAUJ40X160-100, matching the bore, stroke, 1/4" port, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. As a non-magnet SKU, this cylinder cannot take a magnetic switch. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X160-100 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 SAUJ40X160-100 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 SUJ40X160-100 Is Used
Variable Pitch Indexing
Allows on-site extend tuning up to 100 mm to alter part spacing without swapping cylinders when product formats change.
Adjustable Diverter Gate
Sets precise pusher extension distances on the fly to handle varying package widths on a single line.
Format Change Pusher
Provides a 60 to 160 mm extend range to accommodate different carton sizes without mechanical rebuilds.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-100 with the SAUJ40X160-100
To replace this discontinued SUJ40X160-100, specify the SAUJ40X160-100 direct equivalent, which preserves the 40 mm bore, 160 mm nominal stroke, 1/4" port, and FA/LB mounting. The 100 mm adjust window is ideal when exact end positions vary in the field. Because this is a non-magnet SKU, it cannot accept sensors; the SAUJ upgrade path supports CMSG/DMSG/EMSG switches (legacy used CS1-B/DS1-B). For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw sets end position and does not lock the load; add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-100
- ✓ 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 SUJ40X160-100 FAQ
Yes, the SUJ40X160-100 is discontinued. The direct replacement is the SAUJ40X160-100, which matches the 40 mm bore, 160 mm stroke, 1/4" port, force, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw allows you to trim the extend stroke by up to 100 mm on-site, giving a usable 60-160 mm extension. The stop sets end position but is not a load lock.
