This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X160-40, 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 SUJ100X160-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X160-40 is a double-acting profile-type standard cylinder with a Ø100mm bore and 160mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X160-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X160-40
The AirTAC SUJ100X160-40 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40mm on-site. With a nominal 160mm stroke, the usable extend range is 120-160mm; the stop sets the end position but is not a load lock. The 1/2" port and M20x1.5 rod end handle high flow, while adjustable 29mm cushions decelerate heavy loads.
This SUJ unit is discontinued; the direct replacement is the SAUJ100X160-40, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors (this SKU used legacy CS1-B/DS1-B and lacks a magnet, so it cannot take a switch). The SAUJ also offers an SAUF built-in-valve variant. A plain cylinder drifts on air loss—use an external rod lock for held loads.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X160-40 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 SUJ100X160-40 Is Used
Press Fit Tuning
Adjusting the extend stroke on-site by up to 40mm allows operators to dial in the exact pressing depth for bearings without swapping cylinders.
Variable Length Diverter
Trimming the extend stroke from 160mm down to 120mm accommodates changing package sizes on a packaging line, ensuring precise diverting contact.
Adjustable End Stop
Setting a specific extend end position for pallet stops allows quick changeover between different pallet heights while maintaining safe deceleration.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X160-40 with the SAUJ100X160-40
To replace the discontinued SUJ100X160-40, specify the direct replacement SAUJ100X160-40, which matches the 160mm stroke, 40mm adjust window, 1/2" port, and FA/LB mounting. Choose the 40mm adjust window if you need field tuning of the extend end position; the external stop is not a lock, so add an external rod lock for held loads. Because this non-magnetic SKU cannot take a switch, the SAUJ upgrade uses CMSG/DMSG/EMSG sensors. For this 160mm stroke, side-load is minimal, but for strokes >=300mm, guide the load to prevent rod bending. Mounting is compatible with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X160-40
- ✓ 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 SUJ100X160-40 FAQ
Yes, the SUJ100X160-40 is discontinued. The direct replacement is the SAUJ100X160-40, which matches the 100mm bore, 160mm stroke, 40mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 40mm, allowing you to trim the extend stroke from the 160mm maximum down to 120mm on-site. The stop sets end position but is not a load lock.
