This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X160-40, 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 SUJ32X160-40
The AirTAC SUJ Adjustable Cylinder SUJ32X160-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X160-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X160-40
The AirTAC SUJ32X160-40 is a discontinued double-acting double-rod profile cylinder with a 160 mm nominal stroke and a 40 mm external stop screw window, letting you trim the extend stroke down to 120 mm on-site. The extruded aluminum profile barrel is notably shorter than a standard cylinder of the same bore. This unit features a 1/8" port, M10x1.25 rod thread, and 21 mm adjustable cushions.
Because the SUJ series is end-of-life, the direct replacement is the SAUJ32X160-40, retaining the same force, adjustability, and FA/LB mounting. This non-magnet SKU cannot accept a switch. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X160-40 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X160-40 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 SUJ32X160-40 Is Used
Variable Pitch Marking
A marking head needing to hit parts at different extend lengths uses the 40 mm stop screw to shift the 160 mm stroke down to 120 mm for shorter workpieces without re-homing the machine.
Adjustable Transfer Pusher
A transfer arm pushing varied carton widths onto a belt trims the extend end position on-site so the pusher plate aligns perfectly with each lane stop.
Variable Depth Sealing
A heat-seal head lowers onto packages of differing heights, using the external stop to set the precise 120-160 mm extend depth for a consistent seal without crushing the goods.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X160-40 with the SAUJ32X160-40
To replace this discontinued SUJ32X160-40, order the direct replacement SAUJ32X160-40, which matches the 32 mm bore, 160 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your fixture requires precise extend positioning between 120 mm and 160 mm. This non-magnet model cannot take a sensor; the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X160-40
- ✓ 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 SUJ32X160-40 FAQ
Yes, the SUJ32X160-40 is discontinued. The direct replacement is the SAUJ32X160-40, which matches the 32 mm bore, 160 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 40 mm adjust window lets you shorten the 160 mm nominal extend stroke down to 120 mm on-site. The stop screw sets the end position but is not a load lock.
