This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X250-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X250-100S 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 SUJ100X250-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-100S is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X250-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-100S
The AirTAC SUJ100X250-100S is a double-acting single-rod profile cylinder with an adjustable stroke, now discontinued. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 150-250 mm range from the 250 mm nominal maximum. The stop sets the end position but is not a load lock. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 thread, and a 1/2" port.
The direct drop-in replacement is the SAUJ100X250-100S, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ profile body allows use of current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. 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 that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X250-100S 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 SAUJ100X250-100S 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 SUJ100X250-100S Is Used
Variable-Length Pressing
Allows operators to dial in the exact 150 to 250 mm extend position for pressing bearings without machining custom spacers.
Adjustable Diverter Arms
Enables field tuning of the pusher stroke by up to 100 mm to accommodate changing package sizes on the fly.
Variable Depth Palletizing
Permits quick on-site adjustments to the extend endpoint when handling pallets of varying heights or depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-100S with the SAUJ100X250-100S
To replace the discontinued SUJ100X250-100S, order the drop-in SAUJ100X250-100S, which preserves the 250 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. If resizing, 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. Choose the adjust window based on your exact on-site extend trim needs (here, shortening the stroke by up to 100 mm). Because this is an -S model, you must switch from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. The stop screw sets end position only; it is not a lock, so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-100S
- ✓ 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 SUJ100X250-100S FAQ
Yes, the SUJ100X250-100S is discontinued. The exact drop-in replacement is the SAUJ100X250-100S, which matches the 100 mm bore, 250 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. You will need to upgrade from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
This 100 mm bore double-acting single-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushes 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa (max 801 kgf at 1.0 MPa). The external stop screw provides a 100 mm adjust window, allowing you to trim the extend stroke on-site from the 250 mm maximum down to 150 mm.
