This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAIJ100X60-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAIJ100X60-30S in place of this model. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S
The AirTAC Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAIJ100X60-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S
The AirTAC B04-SIJ100X60-30S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder. The B04- prefix marks it as the construction-machinery dedicated variant of the base SIJ100X60-30S, mechanically identical to the standard line. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 30-60 mm. This 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, features a G1/2 port, and includes a -S piston magnet for position sensing.
This SIJ model is discontinued and the exact drop-in replacement is the SAIJ100X60-30S, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 2356 N (60% of the 3927 N push at 0.5 MPa), yielding a vertical lift capacity of about 200 kg with a 2:1 margin. Note that the stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant 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 B04-SAIJ100X60-30S 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.

Where the Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S Is Used
Excavator Panel Positioning
Field-tunes the extend stroke by up to 30 mm on-site to align heavy cab panels without remachining stops, leveraging 3927 N push at 0.5 MPa.
Crane Outrigger Locking
Adjusts the extend endpoint precisely for outrigger deployment pins in varying site conditions, using the 30-60 mm usable stroke window.
Concrete Pump Actuation
Trims the extend stroke on-site to accommodate wear in concrete pump linkages, ensuring proper seating without cycle timing changes.
Replacing the Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S with the B04-SAIJ100X60-30S
To replace the discontinued B04-SIJ100X60-30S, order the drop-in SAIJ100X60-30S, ensuring you keep the -S magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore yields 6136 N; this 100 mm bore provides 3927 N push at 0.5 MPa (7068 N at 0.9 MPa). The 30 mm adjust window is ideal if your construction-machinery fixture needs field tuning between 30 and 60 mm. Reuse your FA, LB, or TC ISO 15552 mounts. Since the 60 mm stroke is under 300 mm, side-load lever arm risks are minimal. The stop screw sets end position only; it is not a lock, and the cylinder will drift on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAIJ100X60-30S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B04-SIJ Construction Machinery Special ISO Standard Cylinder B04-SIJ100X60-30S FAQ
Yes, the B04-SIJ100X60-30S (construction-machinery dedicated variant of SIJ100X60-30S) is discontinued. The exact drop-in replacement is the SAIJ100X60-30S, offering the same ISO 15552 interface, 100 mm bore, 60 mm stroke, 30 mm adjust window, G1/2 port, and -S magnet. The SAIJ adds an upgraded two Y-shaped one-way piston seal.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 30 mm adjust window, allowing you to shorten the 60 mm nominal extend stroke down to 30 mm on-site. The stop sets end position and is not a load lock.
