This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X200-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X200-20 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 SUJ100X200-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X200-20 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 SAUJ100X200-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X200-20
The AirTAC SUJ100X200-20 is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 180-200 mm extension out of the 200 mm nominal maximum. It delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa. The 1/2" port, Ø25 mm rod, and M20x1.5 rod thread handle robust dynamics, while the 29 mm adjustable air cushions decelerate heavy loads smoothly. The stop screw strictly sets the end position and is never a load lock.
For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Because this SUJ is discontinued, the exact drop-in replacement is the SAUJ100X200-20, matching the bore, stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note this non-magnetic SKU cannot accept a switch. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X200-20 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 SAUJ100X200-20 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.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×200 | 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 SUJ100X200-20 Is Used
Press Fit Tuning
Allows operators to dial in the exact 180-200 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke to deflect different package sizes on a packaging line, accommodating format changes quickly.
Adjustable Stop Gate
Sets a precise physical stop for pallets, letting maintenance trim the 20 mm window to align with conveyor transfers perfectly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X200-20 with the SAUJ100X200-20
To replace the discontinued SUJ100X200-20, order the drop-in SAUJ100X200-20, which preserves the 100 mm bore, 200 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N at 0.5 MPa or 5497 N at 0.7 MPa. Choose the 20 mm adjust window if you need precise field tuning of the extend stroke between 180 and 200 mm. Since this SKU lacks a magnet, it cannot take a switch; if you need sensing on the SAUJ, specify the -S option and use current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X200-20
- ✓ 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 SUJ100X200-20 FAQ
Yes, the AirTAC SUJ100X200-20 is discontinued. The exact drop-in replacement is the SAUJ100X200-20, matching the 100 mm bore, 200 mm stroke, 20 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.
The double-acting single-rod cylinder pushes 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa, with 3681 N pull at 0.5 MPa and an 801 kgf theoretical max at 1.0 MPa. The external stop screw trims the extend stroke by up to 20 mm on-site, giving a 180-200 mm usable range out of the 200 mm nominal maximum. The stop sets end position only and does not lock the load.
