This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-50 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 SUJ32X500-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X500-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-50
The AirTAC SUJ32X500-50 is a double-acting single-rod profile cylinder with a 500 mm nominal stroke and a 50 mm external stop screw window, allowing you to trim the extend stroke on-site to any usable length between 450 and 500 mm. This compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force through a 1/8" port, with adjustable 21 mm cushions at each end to manage deceleration.
This SUJ model is discontinued and the exact drop-in replacement is the SAUJ32X500-50, which matches the 32 mm bore, 500 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 20 kg with a 2:1 margin. Note this non-magnet SKU cannot take a switch, and the stop screw sets end position rather than locking the load.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-50 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 SAUJ32X500-50 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 SUJ32X500-50 Is Used
Variable Pitch Pushing
Feeding different length blanks on a single line by dialing the extend stroke within the 50 mm window without swapping the cylinder.
Adjustable End Diverter
Tuning a diverting gate stop on-site to handle varying package sizes precisely within the 450 to 500 mm travel range.
Packaging Format Changeover
Accommodating multiple carton sealing depths by trimming the extend stroke on the machine rather than repositioning hardware.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-50 with the SAUJ32X500-50
To replace the discontinued SUJ32X500-50, order the drop-in SAUJ32X500-50, which preserves the 32 mm bore, 500 mm max stroke, 50 mm adjust window, and 1/8" port. When sizing both ways, the neighboring 40 mm bore offers 628 N push at 0.5 MPa if more force is needed, while smaller bores drop force significantly. The 50 mm external stop window is ideal if your end-stop varies by up to 50 mm, beating a fixed SAU plus external stop. Mounting uses basic, FA, or LB brackets compatible with the AirTAC SC series. Because this SKU lacks a magnet, it cannot accept a sensor; the SAUJ upgrade path uses CMSG/DMSG/EMSG switches. At 500 mm stroke, prevent rod bending by supporting side loads with external guides. The stop screw only sets end position; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-50
- ✓ 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 SUJ32X500-50 FAQ
Yes, the SUJ32X500-50 is discontinued. The exact drop-in replacement is the SAUJ32X500-50, matching the 32 mm bore, 500 mm stroke, 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 max of 82 kgf at 1.0 MPa. The external stop screw trims the extend stroke by up to 50 mm on-site, yielding a usable 450-500 mm stroke. The stop sets end position only; it is not a load lock.
