This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X100-50TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X100-50TC 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 SUJ100X100-50TC
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-50TC is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X100-50TC, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-50TC
The AirTAC SUJ100X100-50TC 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, yielding a usable 50-100 mm extend out of the 100 mm nominal maximum. Built on an extruded aluminum profile barrel that is shorter than a standard same-bore cylinder, it features a 25 mm rod, M20x1.5 rod thread, adjustable 29 mm cushions, and a 1/2" port. This SKU has no magnet and cannot take a switch.
As a discontinued model, the exact drop-in replacement is the SAUJ100X100-50TC, which preserves the bore, stroke, 50 mm adjust window, 1/2" port, and TC mounting interface. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches, and the SAU family adds an SAUF built-in-valve variant. At 0.5 MPa this 100 mm bore delivers 3927 N push and 3681 N pull force, giving a safe working load of roughly 2356 N or a 200 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-50TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X100-50TC 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X100-50TC
| SU | Profile-type standard cylinder (discontinued). |

| 100 | 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 SUJ100X100-50TC Is Used
Variable Stroke Pressing
Allows operators to dial in the exact 50-100 mm extend position for pressing bearings without swapping the entire cylinder.
Adjustable Diverter Arms
Tunes the extend length on-site to accommodate different package sizes on a packaging line using the TC mount.
Custom End-Stop Positioning
Sets a precise external mechanical stop for end-of-stroke positioning where repeatable hard contact is required.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-50TC with the SAUJ100X100-50TC
To replace the discontinued SUJ100X100-50TC, order the SAUJ100X100-50TC drop-in, which keeps the TC mounting interface and 1/2" port. If resizing, the 80 mm bore neighbor gives 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the 50 mm adjust window when you need field tuning of the extend stroke between 50 and 100 mm. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ -S variant supports CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify your side-load limits. Remember the stop screw is not a load lock—add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-50TC
- ✓ 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 SUJ100X100-50TC FAQ
Yes, the SUJ100X100-50TC is discontinued. The exact drop-in replacement is the SAUJ100X100-50TC, which matches the 100 mm bore, 100 mm stroke, 50 mm adjust window, 1/2" port, and TC mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting single-rod 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjust window, allowing you to trim the 100 mm nominal extend stroke down to 50 mm on-site. The stop sets end position but is not a load lock.
