This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the drop-in replacement SAUJ32X55-10S, 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 SUJ32X55-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X55-10S is a double-acting profile-type standard cylinder with a Ø32mm bore and 55mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X55-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X55-10S
The AirTAC SUJ32X55-10S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 45-55 mm extension out of the 55 mm nominal maximum. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads. This bore delivers 402 N push and 345 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa, with a 1/8" port and M10x1.25 rod thread.
This SUJ32X55-10S unit is discontinued and the exact drop-in replacement is the SAUJ32X55-10S, retaining the same 32 mm bore, 55 mm stroke, 10 mm adjust window, force, and port. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. For sizing, the safe working load is roughly 241 N (about 60% of the 402 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 20 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X55-10S 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 SAUJ32X55-10S produces the same force from the same bore — a true drop-in on output. 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 SUJ32X55-10S Is Used
Gripper Jaw Timing
Dial in the exact extend stop within the 45-55 mm window to synchronise gripper jaw travel without machining custom spacers.
Light Part Ejection
Trim the extend stroke on-site to push small parts clear of a fixture, using the 402 N push force at 0.5 MPa for reliable ejection.
Sensor Probe Positioning
Set a precise probe contact depth by adjusting the external stop screw, ensuring the 1/8" port cylinder bottoms out accurately.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X55-10S with the SAUJ32X55-10S
To replace the discontinued SUJ32X55-10S, order the drop-in SAUJ32X55-10S, which matches the 32 mm bore, 55 mm stroke, 10 mm adjust window, 1/8" port, and SC-series FA/LB mounting. Because the stop screw trims extend stroke by up to 10 mm on-site, choose the 10 mm window when you need precise end-position tuning without shimming. If you need more force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa; if you can accept less force, there is no smaller standard bore in this family. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. Since the 55 mm stroke is under 300 mm, side-load rod deflection is minimal, but always confirm the rod-end thread M10x1.25 matches your mechanics.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X55-10S
- ✓ 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 SUJ32X55-10S FAQ
Yes, the SUJ32X55-10S is discontinued. The exact drop-in replacement is the SAUJ32X55-10S, which shares the same 32 mm bore, 55 mm stroke, 10 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to shorten the 55 mm nominal extend stroke down to 45 mm on-site.
