Hedgehog Studio "Kattobi" Tuning Kit Ceramic Ball Bearings | Shimano 730 & 730 Air

With the "Kattobi" Bearing Tuning Kit, you get a premium bearing set from Japan for your baitcasting reel. The kit includes 2 bearings with the bearing size 730Air (3mm x 7mm x 3mm).

The small ceramic balls are installed so precisely in the housing that they start to spin with the slightest weights. This makes the fishing reel perform incredibly well, with an extremely high rotation speed on one hand and a very smooth operation on the other.

Squeeze out the last bit of distance!

The Air Ceramic Bearing Set is aimed at anglers using light lures who primarily cast lures weighing 1 - 28 g. With the bearing, you achieve on average 10 - 30% more casting distance. It doesn’t sound like much, but with a casting distance of 30 m, you get up to 9 m more out of your reel compared to factory bearings. This allows you to fish spots that were previously out of your casting range.

Why use tuning bearings?

In general, bearings installed in reels from the factory often do not have good rotational properties because a lot of grease and dust prevent smooth operation.

The AIR Ceramic Tuning Kit comes pre-oiled, and the in-house Alchemy Oil from Hedgehog Studio ensures the perfect balance between oil and bearing.

The "Kattobi" bearings undergo quality control; after assembly, they are checked by hand, and only bearings with excellent rotational performance are allowed to leave the facility.

Therefore, it is not necessary to clean or lubricate the bearings. The bearings can be used out-of-the-box.
