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

About the Airtac SUJ Adjustable Cylinder SUJ32X500-100S
The AirTAC SUJ32X500-100S is a double-acting, single-rod profile cylinder with a 32 mm bore and 500 mm nominal 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. The extruded aluminum profile barrel is more compact than a standard cylinder of the same bore. This discontinued model generates 402 N push and 345 N pull at 0.5 MPa, scaling to 563 N at 0.7 MPa and 724 N at 0.9 MPa. It features a 1/8" port, a Ø12 mm rod, and adjustable 21 mm cushions.
AirTAC has discontinued the SUJ series; the exact drop-in replacement is the SAUJ32X500-100S, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit uses CS1-B/DS1-B switches. For sizing, a safe working load is roughly 241 N (60% of the 402 N push), translating to a 20 kg vertical lift with a 2:1 margin. Note that the stop screw sets end position but is not a load lock; drifting occurs on air loss, requiring an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-100S 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 SAUJ32X500-100S 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 SUJ32X500-100S Is Used
Variable Pitch Indexing
Tuning the extend stroke on-site by up to 100 mm allows a single 500 mm cylinder to drive multiple variable pitch indexes without swapping the entire actuator.
Adjustable Reject Pusher
Trimming the extend stroke accommodates changing package widths on a conveyor line, ensuring the pusher travels the exact distance needed for each product.
Variable Height Diverter
A 400-500 mm usable stroke window lets operators manually set the diverter reach for different pallet heights without reprogramming machine logic.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-100S with the SAUJ32X500-100S
To replace the discontinued SUJ32X500-100S, order the drop-in SAUJ32X500-100S, which matches the 32 mm bore, 500 mm max stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. When sizing both ways, the neighboring 40 mm bore offers higher force (628 N push @0.5 MPa) if the 402 N output is insufficient, while smaller bores reduce footprint. Choose the 100 mm adjust window if your application requires field-tuning the extend stroke down to 400 mm; for fixed positions, a standard SAU cylinder suffices. Because this unit has the -S magnet, you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. At 500 mm stroke, prevent rod bending by managing side loads with external guides. The stop screw defines end position but does not hold loads pneumatically; add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-100S
- ✓ 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 SUJ32X500-100S FAQ
Yes, the AirTAC SUJ32X500-100S is discontinued. The exact drop-in replacement is the SAUJ32X500-100S, which matches 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 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 allows you to trim the extend stroke by up to 100 mm on-site, giving a usable 400-500 mm stroke. The stop sets end position but is not a load lock.
