AIR Bearings are ultra-high-speed bait finesse bearings ideal for lures ranging from 1g to approximately 28g.

Thanks to the adoption of small-diameter Japanese-made ceramic balls and a high-strength integrated housing, these bearings are not only perfect for bait finesse but also provide the rotational responsiveness to cast ultra-lightweight lures. At the same time, they allow you to cast 1oz-class lures with the same feel as regular bearings.

These versatile bearings excel in various scenarios. Once you cast with them, you will notice the difference—experience the ultimate rotational responsiveness of AIR Bearings.

*“AIR Bearings” are registered trademarks and design-registered products of HEDGEHOG STUDIO.








AIR BFS-Si bearings allow you to easily replace the main micro bearing by removing the built-in stopper ring from the outer housing. This structure offers excellent maintainability, making it a highly cost-effective bearing.
Replacement micro ceramic bearings and stopper rings are also available for purchase separately.
