This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ32X70-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ32X70-50S 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 SUJ32X70-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X70-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 70mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ32X70-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X70-50S
The AirTAC SUJ32X70-50S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. The nominal 70 mm stroke is the maximum, yielding a usable extend range of 20-70 mm. This compact aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. At 0.5 MPa it delivers 402 N push and 345 N pull force, operating at 30-800 mm/s through a 1/8" port.
The exact drop-in replacement is the SAUJ32X70-50S, sharing the same 32 mm bore, 70 mm stroke, force, port, and FA/LB mounting. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors, which upgrade to CMSG/DMSG/EMSG on the SAUJ. Computed buyer insight: safe working load is ~241 N (60% of 402 N), enabling a ~20 kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X70-50S 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 SAUJ32X70-50S 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.

| 32 | Bore size in mm. |
| ×70 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X70-50S Is Used
Variable Depth Drilling
Adjusting the extend stroke on-site to set precise drilling depths into different material thicknesses without changing the entire cylinder.
Dynamic Sorting Diverter
Tuning the pusher extension distance on a packaging line to handle varying box widths on the fly.
Adjustable Stop Positioning
Setting a hard mechanical stop for incoming pallets or parts where the required engagement distance frequently changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X70-50S with the SAUJ32X70-50S
To replace the discontinued SUJ32X70-50S, order the drop-in SAUJ32X70-50S. If resizing, the adjacent 40 mm bore offers 628 N push at 0.5 MPa, while the smaller bores drop force. Choose the 50 mm adjust window if you need to trim the 70 mm extend stroke down to 20 mm on-site; the stop sets end position but does not lock the load. Retain FA or LB mounts (SC-series compatible). Because this model has the -S magnet, you must replace legacy CS1-B/DS1-B sensors with current CMSG/DMSG/EMSG switches. For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X70-50S
- ✓ 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 SUJ32X70-50S FAQ
Yes, the SUJ32X70-50S is discontinued. The exact drop-in replacement is the SAUJ32X70-50S, offering the same 32 mm bore, 70 mm stroke, 1/8" port, and FA/LB mounting. You must upgrade the -S piston magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 32 mm bore 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 (max 82 kgf at 1.0 MPa). The external stop screw provides a 50 mm adjust window, allowing you to shorten the 70 mm nominal extend stroke down to 20 mm on-site. The stop sets end position but is not a load lock.
