This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ50X100-75SFA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ50X100-75SFA 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 SUJ50X100-75SFA
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-75SFA is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ50X100-75SFA, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-75SFA
The AirTAC SUJ50X100-75SFA is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 25-100 mm stroke from the 100 mm nominal maximum. The 50 mm bore delivers 982 N push and 825 N pull at 0.5 MPa, scaling to 1767 N at 0.9 MPa, via a 1/4" port. This DISCONTINUED model maps directly to the SAUJ50X100-75SFA drop-in replacement, retaining the exact bore, stroke, force, and FA mounting interface.
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. For sizing, the 982 N @0.5 MPa push yields a safe working load of ~589 N (60%), or a ~50 kg vertical lift with a 2:1 margin. The SAUJ upgrade keeps the compact profile barrel and FA mount but transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-75SFA 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 SAUJ50X100-75SFA 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.

| 50 | Bore size in mm. |
| ×100 | 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 SUJ50X100-75SFA Is Used
Variable Depth Drilling
Allows operators to tune the extend stroke on-site for parts of varying heights without reprogramming the motion controller.
Adjustable Forming Press
Provides a 25-100 mm extend window to accommodate different carton depths or material thicknesses on a shared line.
Custom Length Diverter
Enables field adjustment of the pusher stroke to route different package sizes without swapping the entire cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-75SFA with the SAUJ50X100-75SFA
To replace the discontinued SUJ50X100-75SFA, order the drop-in SAUJ50X100-75SFA, which matches the 50 mm bore, 100 mm max stroke, 75 mm adjust window, 1/4" port, and FA mounting. When sizing both ways, the neighboring 40 mm bore provides 879 N push @0.7 MPa, while the 63 mm bore offers 2182 N @0.7 MPa. Choose the 75 mm adjust window when you need significant on-site extend stroke trimming (down to 25 mm). The FA mount is an SC-series accessory. Because this unit has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For any stroke >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-75SFA
- ✓ 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 SUJ50X100-75SFA FAQ
Yes, the SUJ50X100-75SFA is discontinued. The exact drop-in replacement is the SAUJ50X100-75SFA, which matches the 50 mm bore, 100 mm stroke, 75 mm adjust window, 1/4" port, and FA mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 50 mm bore provides 982 N push and 825 N pull @0.5 MPa, 1374 N push @0.7 MPa, and 1767 N push @0.9 MPa. The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 25-100 mm from the 100 mm nominal maximum.
