This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAI50X450S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAI50X450S 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-SI50X450S
The AirTAC Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X450S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 450mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAI50X450S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X450S
The AirTAC B06-SI50X450S is a discontinued double-acting ISO 15552 profile cylinder. The B06- prefix marks it as a battery-manufacturing dedicated variant of the SI50X450S, mechanically identical to the base model with a 50mm bore, 450mm stroke, G1/4 port, and 982N push force at 0.5MPa. AirTAC replaced this EOL unit with the SAI50X450S, a true drop-in sharing the same interface, force, and porting.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For battery line integration, the safe working load is roughly 589N (60% of the 982N push force), allowing a vertical lift of about 50kg with a 2:1 margin. The original SI used CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. For high-temp zones, Viton H seals raise the operating range to 150C.

Where the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X450S Is Used
Cell Stacking Press
Applies the 982N push force at 0.5MPa to align and press prismatic battery cells during module stacking, using the 450mm stroke to accommodate varying stack heights.
Module Transfer
Extends 450mm to push battery modules between assembly stations, relying on the ISO 15552 mounting interface for rigid fixture integration on the production line.
Tab Welding Feed
Positions battery tabs for laser welding with a 50kg vertical lift capacity, utilizing the adjustable 30mm air cushions to decelerate the payload smoothly at stroke end.
Replacing the Airtac B06-SI Battery Dedicated ISO Standard Cylinder B06-SI50X450S with the B06-SAI50X450S
To replace the B06-SI50X450S, order the SAI50X450S drop-in. Verify the ISO 15552 mounting interface, 50mm bore, 450mm stroke, G1/4 port (PT/G/NPT), and the -S magnet for current AirTAC switches. Sizing both ways: a 40mm bore yields 628N push at 0.5MPa, while a 63mm bore yields 1559N. A plain cylinder drifts on air loss since cushions only decelerate; for battery stack holding, use an external pilot check valve or the SAIL/BSAI lock variants. With a 450mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B06-SAI50X450S
- ✓ 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-SI50X450S FAQ
Yes, the B06-SI50X450S (battery-manufacturing dedicated SI50X450S) is discontinued. The exact drop-in replacement is the AirTAC SAI50X450S. It is dimensionally interchangeable per ISO 15552, retaining the same 50mm bore, 450mm stroke, G1/4 port, and mounting interface.
The 50mm bore features a G1/4 air port. At 0.5MPa it provides 982N push and 825N pull force. At 0.7MPa push is 1374N, and at 0.9MPa it is 1767N. The theoretical maximum force is 200kgf at 1.0MPa. Speed ranges from 30-800mm/s.
