This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X220-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X220-30S 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 SUJ100X220-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X220-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 220mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X220-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X220-30S
The AirTAC SUJ100X220-30S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 190-220 mm extend out of the 220 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa, via a 1/2" port and Ø25 mm rod. This compact extruded barrel is shorter than standard cylinders of the same bore.
Because the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ100X220-30S, preserving the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves the -S magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a load lock, so add an external rod lock for held loads.

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 SAUJ100X220-30S 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 SUJ100X220-30S Is Used
Variable Pitch Forming
Bending or pressing operations where the extend stop must be dialed in precisely between 190 and 220 mm on-site to accommodate material thickness variations without reprogramming the machine.
Adjustable Diverter Gate
Routing products of varying sizes on a line by trimming the actuator's extend stroke up to 30 mm to position the guide flap exactly where needed for each product run.
Variable Depth Pusher
Pushing cartons into packaging cases where the required extend distance fluctuates by a few centimeters, allowing operators to set the exact 190-220 mm insertion depth mechanically.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X220-30S with the SAUJ100X220-30S
To replace the discontinued SUJ100X220-30S, specify the SAUJ100X220-30S as a direct drop-in retaining the 100 mm bore, 220 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N; choose the 100 mm if you need the higher 7068 N push at 0.9 MPa. The -30 adjust window is ideal when final extend position needs on-site tuning between 190 and 220 mm. For the -S magnet version, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. Since the 220 mm stroke is under 300 mm, side-load lever arm is minimal, but always verify rod buckling if pushing heavy loads. The external stop screw sets end position and is not a load lock; use an external rod lock for holding loads without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X220-30S
- ✓ 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 SUJ100X220-30S FAQ
Yes, the SUJ100X220-30S is discontinued. The exact drop-in replacement is the SAUJ100X220-30S, which matches the 100 mm bore, 220 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the -S magnet sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
This double-acting single-rod cylinder has a 30 mm adjust window (usable extend stroke 190-220 mm). It delivers 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. It uses a 1/2" port and the stop screw sets end position only, not a load lock.
