This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X150-50TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X150-50TC 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 SUJ50X150-50TC
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X150-50TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X150-50TC, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X150-50TC
The AirTAC SUJ50X150-50TC is a 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 150 mm stroke is the maximum, yielding a usable extend range of 100-150 mm. This discontinued adjustable-stroke unit features a 50 mm bore, a 1/4" port, and delivers 982 N push and 825 N pull at 0.5 MPa. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.
As the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ50X150-50TC, retaining the same bore, stroke, force, port, and TC mounting interface. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Note that this specific SKU lacks a magnet and cannot take a switch. For sizing, the 982 N push at 0.5 MPa yields a safe working load of about 589 N (60% factor) and a vertical lift capacity of roughly 50 kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X150-50TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X150-50TC 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 SUJ50X150-50TC Is Used
Variable Pitch Indexing
Needs field stroke tuning to alter the push distance for parts of varying widths without swapping the entire cylinder.
Adjustable Diverter Gate
Requires trimming the extend stroke by up to 50 mm on-site to deflect different package sizes accurately on a moving belt.
Variable Depth Sealing
Demands precise end-position adjustment via the stop screw to seal cartons of varying depths while avoiding overtravel.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X150-50TC with the SAUJ50X150-50TC
To replace the discontinued SUJ50X150-50TC, order the drop-in SAUJ50X150-50TC, which matches the 50 mm bore, 150 mm stroke, 50 mm adjust window, 1/4" port, and TC mounting. When sizing both ways, the neighboring 40 mm bore provides 628 N push at 0.5 MPa, while the 63 mm bore offers 1559 N push at 0.5 MPa. Choose the 50 mm adjust window if you need to trim the extend stroke by up to 50 mm on-site; the stop screw sets end position but is not a lock. Mounting uses SC-series accessories including the TC interface. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ replacement uses CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X150-50TC
- ✓ 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 SUJ50X150-50TC FAQ
Yes, the SUJ50X150-50TC is discontinued. The exact drop-in replacement is the SAUJ50X150-50TC, which matches the 50 mm bore, 150 mm stroke, 50 mm adjust window, 1/4" port, and TC mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 50 mm bore double-acting single-rod cylinder pushes 982 N and pulls 825 N at 0.5 MPa, pushes 1374 N at 0.7 MPa, and 1767 N at 0.9 MPa, with a theoretical max of 200 kgf at 1.0 MPa. The external stop screw window is 50 mm, allowing you to trim the extend stroke from the 150 mm maximum down to 100 mm on-site.
