This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X100-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X100-30S 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 SUJ100X100-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-30S 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 SAUJ100X100-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-30S
The AirTAC SUJ100X100-30S is a double-acting, single-rod adjustable-stroke profile cylinder featuring a 100 mm bore and a 1/2 inch port. An external stop screw allows you to trim the extend stroke by up to 30 mm on-site, yielding a usable 70-100 mm extension out of the 100 mm nominal maximum. This bore delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. For sizing context, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of approximately 200 kg with a 2:1 margin.
This SUJ unit is discontinued and the exact drop-in replacement is the SAUJ100X100-30S, which matches the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches fitted to this -S model. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so add an external rod lock for held loads. The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-30S 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 SAUJ100X100-30S 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 SUJ100X100-30S Is Used
Variable Depth Spot Facing
Needs field stroke tuning to set precise facing depths on cast parts without reprogramming the machine controller.
Adjustable Transfer Pusher
Requires trimming the extend stroke on-site to accommodate changing package widths on a packaging line.
Tiered Pallet Positioning
Demands an adjustable end position to engage different pallet stack heights accurately during loading.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-30S with the SAUJ100X100-30S
To replace the discontinued SUJ100X100-30S, order the SAUJ100X100-30S for an exact drop-in match on bore, stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N push at 0.5 MPa (7068 N at 0.9 MPa). Choose the 30 mm adjust window when you need on-site extend trimming between 70 and 100 mm. Because this unit has a -S magnet, you must upgrade your sensing to CMSG/DMSG/EMSG switches (the SUJ used CS1-B/DS1-B). For strokes of 300 mm or longer, verify your side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-30S
- ✓ 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 SUJ100X100-30S FAQ
Yes, the SUJ100X100-30S is discontinued. The exact drop-in replacement is the SAUJ100X100-30S, which matches the 100 mm bore, 100 mm stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. You will need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG 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 (801 kgf max at 1.0 MPa). The external stop screw window is 30 mm, allowing you to trim the extend stroke on-site from the 100 mm maximum down to 70 mm. The stop sets end position and is not a load lock.
