This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X100-50SN, 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 SUJ32X100-50SN
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X100-50SN is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X100-50SN, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X100-50SN
The AirTAC SUJ32X100-50SN is a double-acting, double-rod profile cylinder with an adjustable stroke, now discontinued and superseded by the direct replacement SAUJ32X100-50SN. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 50-100 mm range from the 100 mm nominal maximum. This compact profile body is shorter than an ISO 15552 cylinder of the same bore.
The SAUJ32X100-50SN replacement retains the exact bore, stroke, force, port, and FA/LB mounting, but upgrades to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X100-50SN 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 SAUJ32X100-50SN 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 SUJ32X100-50SN Is Used
Variable Pusher Stops
Adjusting the extend stroke on-site by up to 50 mm allows a pusher station to handle different carton depths without swapping cylinders.
Calibrated Forming Pins
Trimming the extend stroke precisely sets the insertion depth of a locating pin in an assembly jig, accommodating material thickness variations.
Adjustable Diverter Arms
Shortening the extend stroke on the fly lets a diverter arm reach different conveyor lanes accurately using the external stop screw.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X100-50SN with the SAUJ32X100-50SN
To replace the discontinued SUJ32X100-50SN, specify the SAUJ32X100-50SN direct, which preserves the 32 mm bore, 100 mm max stroke, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if you need to trim the extend stroke on-site by up to 50 mm; if you need less variability, a fixed SAU might suffice. When migrating, note the -S sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X100-50SN
- ✓ 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 SUJ32X100-50SN FAQ
Yes, the SUJ32X100-50SN is discontinued. The direct replacement is the SAUJ32X100-50SN, which maintains the same 32 mm bore, 100 mm stroke, 1/8" port, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 50 mm adjust window, allowing you to trim the extend stroke from the 100 mm maximum down to 50 mm on-site.
