This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X200-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X200-50S 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 SUJ100X200-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X200-50S is a double-acting profile-type standard cylinder with a Ø100mm bore and 200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X200-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X200-50S
The AirTAC SUJ100X200-50S 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, yielding a usable 150-200 mm stroke from the 200 mm nominal maximum. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa, with a 1/2" port and 29 mm adjustable cushions. The stop sets the end position but is not a lock; loads drift on air loss.
This SUJ unit is discontinued and replaced by the drop-in SAUJ100X200-50S, which retains the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this -S model uses legacy CS1-B/DS1-B switches. For sizing, the 3927 N push at 0.5 MPa yields a safe working load of roughly 2356 N (60% margin) and a vertical lift capacity near 200 kg with a 2:1 safety factor. The compact profile barrel is shorter than standard bodies of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X200-50S 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 SAUJ100X200-50S 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.

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 SUJ100X200-50S Is Used
Variable Depth Boring
Adjusts the extend stroke on-site to machine recesses of varying depths without swapping the entire actuator assembly.
Variable Height Sealing
Trims the extend stroke to seat sealing heads precisely against cartons of differing heights on a packaging line.
Adjustable Transfer Stops
Tunes the extend length to act as a physical stop for products of varying widths on a conveyor system.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X200-50S with the SAUJ100X200-50S
To replace the discontinued SUJ100X200-50S, order the drop-in SAUJ100X200-50S, matching the 100 mm bore, 200 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. Choose the 50 mm adjust window if your extend stroke needs field tuning between 150 and 200 mm. The -S suffix means a piston magnet for legacy CS1-B/DS1-B sensors; the SAUJ replacement requires current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod bearing wear. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X200-50S
- ✓ 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 SUJ100X200-50S FAQ
Yes, the SUJ100X200-50S is discontinued. The exact drop-in replacement is the SAUJ100X200-50S, offering the same 100 mm bore, 200 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 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 window is 50 mm, allowing you to shorten the 200 mm nominal extend stroke down to 150 mm on-site. The stop sets end position only; it is not a load lock.
