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.

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

*Note 1*
The following reels cannot use AIR BFS Bearings due to their unique spools:
- 24 STEEZ SV TW
- 21 STEEZ LTD SV TW
- 21 ZILLION SV TW

*Note 2*
STEEZ AIR TW cannot be fitted with bearings other than 1030AIR BFS (SW, Si) due to its special small-diameter spool.
Additionally, the Spool Bearing Remover Type: R cannot be used.
When replacing bearings, please use the SLP WORKS Spool BB Remover II.






The SV spools in this group feature a 3mm slim shaft, making the Spool Bearing Remover Type G more convenient for bearing replacement.

- While the Spool Bearing Remover Type R can also be used without any issues, if you have not yet tried the Type G, we recommend renting it to experience its ease of use.



- The SV spools come with a cover on the outside of the stock bearings.
- Since the cover is reused, only the internal bearings need to be replaced.



- For the bearing on the magnetic brake side, facing the shielded side outward helps prevent the entry of foreign objects and moisture into the bearing, maintaining high rotational performance.
- This is a convenient feature unique to reversible bearings with one open side and one shielded side.

- Detailed instructions for replacement can be found on the page below.
