This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X65-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X65-20S in place of this model. 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 SUJ32X65-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X65-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 65mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X65-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X65-20S
The AirTAC SUJ32X65-20S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 45-65 mm extension from the 65 mm nominal maximum. This discontinued 32 mm bore model delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and relies on adjustable 21 mm air cushions to decelerate the load near stroke end. The stop screw sets the end position firmly but is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
Because the SUJ32X65-20S is end-of-life, the exact drop-in replacement is the SAUJ32X65-20S, keeping the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades the -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 241 N (about 60% of the 402 N push figure), translating to a vertical lift capacity of about 20 kg with a 2:1 margin. Its compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore, making it ideal for tight machinery.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X65-20S 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 SAUJ32X65-20S 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 SUJ32X65-20S Is Used
Probe Contact Tuning
Testing stations needing precise probe touchdown depth can field-trim the 45-65 mm extend stroke to dial in exact contact force without re-machining stops.
Variable Length Diverter
Package diverters handling mixed box sizes use the 20 mm on-site adjust window to alter the pusher stroke length for different product widths on the fly.
Adjustable Push-off Ejector
Assembly line ejectors utilize the external stop screw to set exact part push-off distances, allowing quick changeovers for varying component sizes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X65-20S with the SAUJ32X65-20S
To replace the discontinued SUJ32X65-20S, order the drop-in SAUJ32X65-20S, which preserves the 32 mm bore, 65 mm nominal stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighbouring 40 mm bore provides higher force (628 N push @0.5 MPa) if you need extra thrust, while the 32 mm bore remains optimal for lighter 241 N safe loads. Choose the 20 mm adjust window if you need to tune the extend stroke down to 45 mm on-site; for fixed 65 mm strokes without tuning, a standard SAU cylinder suffices. The -S suffix indicates a piston magnet; you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. Mounting accessories are compatible with the AirTAC SC series only. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X65-20S
- ✓ 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 SUJ32X65-20S FAQ
Yes, the SUJ32X65-20S is discontinued. The exact drop-in replacement is the SAUJ32X65-20S, which matches the 32 mm bore, 65 mm stroke, 20 mm adjust window, and 1/8" port. You must upgrade the -S magnet switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
This double-acting single-rod cylinder delivers 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 20 mm adjust window, shortening the extend stroke from the 65 mm maximum down to 45 mm. The stop sets end position but is not a load lock.
