This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X500-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X500-100 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 SUJ32X500-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-100 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 SAUJ32X500-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-100
The AirTAC SUJ32X500-100 is a double-acting, single-rod profile cylinder with a 32 mm bore and 500 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 400-500 mm window for field tuning without changing mounts. The extruded aluminum profile barrel is more compact than an ISO 15552 unit of the same bore. Operating at 0.5 MPa, it delivers 402 N push and 345 N pull force through a 1/8" port. This bore uses a 12 mm rod with an M10x1.25 thread and 21 mm adjustable cushions.
This SUJ model is DISCONTINUED. The exact drop-in replacement is the SAUJ32X500-100, which matches the bore, stroke, 100 mm adjust window, force, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here. Because this specific SKU lacks a magnet, it cannot take a magnetic switch. For sizing, a safe working load is roughly 241 N (60% of the 402 N push force), translating to a 20 kg vertical lift with a 2:1 safety margin. 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 SAUJ32X500-100 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 SAUJ32X500-100 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.

Where the Airtac SUJ Adjustable Cylinder SUJ32X500-100 Is Used
Variable-Length Ejector Stroke
Trimming the extend stroke by up to 100 mm on-site allows an ejection fixture to adapt to mixed product lengths without machining new hard stops.
Adjustable Transfer Pusher
A 400-500 mm usable stroke window lets operators fine-tune the pusher end position in the field to match varying pallet widths on a line.
Field-Tuned Carton Flap Folder
The external stop screw provides exact flap folding depth on-site, accommodating different box sizes while maintaining the 402 N push force.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-100 with the SAUJ32X500-100
To replace the discontinued SUJ32X500-100, order the drop-in SAUJ32X500-100, which preserves the 32 mm bore, 500 mm nominal stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore provides 628 N push at 0.5 MPa if more force is needed, while the smaller bores offer less thrust. Choose the 100 mm adjust window if your fixture requires precise 400-500 mm extend tuning on-site; the external stop screw sets the end position but is not a load lock, so add an external rod lock for held loads. Because this SKU has no magnet, it cannot accept sensors; the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Finally, at 500 mm stroke, mind the side-load and rod-bending limits by using external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-100
- ✓ 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 SUJ32X500-100 FAQ
Yes, the SUJ32X500-100 is discontinued. The exact drop-in replacement is the SAUJ32X500-100, matching the 32 mm bore, 500 mm stroke, 100 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.
The double-acting single-rod cylinder delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and 724 N push at 0.9 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The external stop screw provides a 100 mm adjust window, allowing a usable extend stroke of 400-500 mm. The stop sets end position but is not a load lock.
