Q. Is it necessary to clean Hedgehog bearings before attaching to reel?

A. No, it isn't.
Generally, bearings available on the market for industrial use and hobbies have no good rotation very often, because relatively hard grease is often clogged up in the inside of the bearing and some dust get inside of the bearing.

Haven't you purchased the bearing of such low-priced editions, washed the them yourself and used them up to now?
Have you ever experienced to heard some noise or felt some rumbling from bearings after cleaning them thoroughly?
You never get good results no matter how many times it its washed, as long as the accuracy of bearing is bad.

All bearings of HEDGEHOG STUDIO are tuned up and coordinated "Just for fishing reels".
All the bearings are selected one by one by our craftsman's hand after assembly, and only the bearings with excellent rotation performance pass the checks.
And they are filled up with the "Alchemy Oil" developed only for the bearing, and are shipped.

Therefore, it is not necessary to clean or to lubricate oil of a different manufacturer since our bearing condition is the highest in performance when they arrive to you.
You will be able to get the best performance by just opening the package of bearings and setting them to your reel.

Q. What is the rating of your (HEDGEHOG HOG’s) bearing in the ABEC (Annular Bearing Engineers' Committee) scale?

A. It is the question we get most often from overseas customers.
Because the bearings of HEDGEHOG STUDIO are Japanese-made products developed exclusively for reels, it is not applied to the ABEC scale which is an American Standard.
However, the performance is the "non-standard" quality and precision which exceeds ABEC9 rating.

Q. Is it easy to replace the bearing?

A. Yes, it comes with installation instructions in the kit, so you can easily replace the bearings the first time.
Moreover, the bearing currently attached in the inner part of the spool shaft is also replaceable by using the spool bearing remover of HEDGEHOG STUDIO.

Q. Does it cause backlash easily because the spool becomes high rotation?

A. On the contrary, it causes backlash less. Casting softly gives rise to sufficient rotational force so that you can make a cast by utilizing the bending of the rod.
Especially, among professional anglers on tours day after day,
There is also much evaluation of being very hard to get tired since useless energy is not nesesarry for casting, and becoming easy to carry out thier control.
However, each person has its own habit in their cast. For anglers who had cast with all thier might up to now, we suggest setting up the brake somewhat stonger at the bebinning then gradually getting used to it.

Q. Is oil lubrication necessary for bearing?

A. Except for some bearings, HEDGEHOG STUDIO's bearings are lubricated with proper amount of Alchemy Oil and then shipped .
(* Alchemy Oil Ultra Light is used for baitcast reels.)

After the purchase, when attaching bearing to reel at first, there is neither necessity for degreasing nor oil lubrication.
However, since the oil film becomes gradually weak after going fishing several times, in that case please put one drop of the Alchemy oil into the bearing, so that the initial performance will last much longer.

Alchemy Oil is a special oil for ultra-low friction.
When lubricated by mixed with a lot of frictional resistance oil of others, there is a fear that bringing down the initial performance.
We recommend lubrication of Alchemy Oil.
