This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X50-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X50-30S 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 SUJ32X50-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X50-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X50-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X50-30S
The AirTAC SUJ32X50-30S is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 20-50 mm extend range from the 50 mm nominal maximum. This discontinued unit delivers 402 N push and 345 N pull at 0.5 MPa, features a 1/8" port, and uses an adjustable 21 mm air cushion at each end.
The direct drop-in replacement is the SAUJ32X50-30S, matching the 32 mm bore, force, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B used here. For sizing, a safe working load is roughly 241 N (60% of the 0.5 MPa push), translating to a 20 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X50-30S 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 SAUJ32X50-30S 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 SUJ32X50-30S Is Used
Gripper Jaw Actuation
Tuning the extend stroke on-site by up to 30 mm allows precise gripping of varying part widths without machining custom spacers.
Transfer Pusher Setup
Adjusting the end position lets operators dial in the exact push distance for parts moving onto a secondary conveyor lane.
Carton Flap Folding
Field-trimming the extend stroke ensures the folding arm meets different box heights perfectly without repositioning the cylinder mount.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X50-30S with the SAUJ32X50-30S
To replace this discontinued SUJ32X50-30S, specify the SAUJ32X50-30S, which retains the 32 mm bore, 50 mm nominal stroke, 30 mm adjust window, and 1/8" port. When sizing both ways, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa if more force is needed, while the smaller bore offers less. Choose the 30 mm adjust window if your fixture needs field-tuning the extend stroke down to 20 mm; this is often preferred over a fixed SAU plus external stop because it saves space. The -S suffix means a piston magnet is present; you must migrate from CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X50-30S
- ✓ 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 SUJ32X50-30S FAQ
Yes, the SUJ32X50-30S is discontinued. The exact drop-in replacement is the SAUJ32X50-30S, which matches the 32 mm bore, 50 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
It provides 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 window is 30 mm, allowing you to shorten the 50 mm nominal extend stroke down to 20 mm on-site. The stop sets end position and is not a load lock.
