This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI50X600 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI50X600 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 B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 600mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI50X600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600
The AirTAC B06-SI50X600 is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix designates it as the battery-manufacturing dedicated variant of the SI50X600, mechanically identical to the base model. It delivers 982 N push and 825 N pull at 0.5 MPa through a 50 mm bore, with a 600 mm stroke and G1/4 port. AirTAC replaced the SI line with the SAI family; order the SAI50X600 as the exact drop-in replacement. It shares the same ISO 15552 mounting interface, bore, stroke, force and port.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks the -S magnet, so it cannot accept a CS1-B/DS1-B sensor. For battery line tasks, the safe working load is roughly 589 N (about 60% of the 982 N push force), yielding a 50 kg vertical lift capacity with a 2:1 margin. If you need load holding on air loss, use the SAIL or BSAI lock variants, as cushions only decelerate.

Specifications follow the official AirTAC SI datasheet (now discontinued). The B06-SAI50X600 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The B06-SAI50X600 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 B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600 Is Used
Cell Stacking Press
Applies the 982 N push force at 0.5 MPa to align and press prismatic cells during module stacking, utilizing the 600 mm stroke for deep press travel.
Pack Transfer Line
Extends 600 mm to push battery packs between conveyor belts, moving loads safely within the 589 N working limit during assembly line transitions.
Tab Welding Clamp
Positions and holds battery tabs for laser welding, requiring external guides over the 600 mm extension to prevent rod deflection and maintain weld accuracy.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600 with the B06-SAI50X600
To replace this discontinued B06-SI50X600, order the SAI50X600. Confirm the ISO 15552 mounting interface, 50 mm bore, 600 mm stroke, G1/4 port (PT/G/NPT thread options) and your mounting accessory. Because this SKU lacks the -S magnet, it cannot support position sensing; order SAI50X600S if you need switches. Sizing both ways: a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore yields 1559 N. At 0.7 MPa this 50 mm bore pushes 1374 N. For battery module handling, note that a plain cylinder drifts without live air; add an external rod lock or pilot check valve for holding. The 600 mm stroke requires external guides to prevent rod bending under side loads. Consider SAIL for air-released locking or SAIF for a built-in valve.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI50X600
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X600 FAQ
Yes, the SI series is discontinued. The exact drop-in replacement is the SAI50X600. It is dimensionally interchangeable per ISO 15552, retaining the same 50 mm bore, 600 mm stroke, G1/4 port and mounting interface. The B06- prefix simply marks the battery-manufacturing dedicated variant, and the SAI replacement shares all physical specs.
The G1/4 port feeds a 50 mm bore yielding 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 30 mm adjustable air cushion at each end. Note this non-magnetic SKU cannot take sensors.
