■ YB-MR63ZZMC3 NSK 630 Ball Bearing Set (4 pieces)

● Made in Japan: High Precision & High Durability

These are high-performance bearings manufactured in Japan, featuring metal retainers. Similar to our existing "520 Ball Bearings" model, they offer exceptional precision, rotational performance, and superior durability.

● Engineered for Maximum Driving Performance

Our unique polishing and finishing process minimizes rotational resistance to the absolute limit, resulting in improved acceleration and handling. They excel particularly in high-speed rotation ranges and offer outstanding smoothness during deceleration, earning high praise across a wide range of applications.

● High Performance, Low Price

As the third product released by NSK Micro Precision, this bearing generated high anticipation even before its launch. During the initial MAR pre-sale, it achieved a sales record of over 100 units in a single week through physical stores alone. Despite its high performance, it features an affordable price point, making it popular among users looking for replacements or upgrades.　

YB-522 ISC MC2 HG 520 Ball Bearing

This is an ISC-manufactured, made-in-Japan, top-tier bearing featuring a metal retainer. It boasts precision levels so high that it is typically not released for general distribution, combined with the extreme durability required to withstand the rigorous testing of Fence Cars (Fencesitter cars).

The design minimizes axial play compared to standard products, allowing for more aggressive tuning and setting adjustments. The adoption of a metal retainer provides superior solvent resistance compared to resin alternatives, ensuring robustness even in harsh environments.

Furthermore, through an advanced super-finishing process and strict abrasive control, rotational resistance has been brought nearly to zero, significantly enhancing cornering speed.

【520ベアリング(MC3)】 
・ISCは主力のベアリング事業において、国内首位、世界3位の市場占有率を有する日本精工株式会社グループのNSKマイクロプレシジョン株式会社です。
・これまでの樹脂製リテーナーより非常に高い精度と高い耐久性を持つ金属リテーナー採用の国産高性能ベアリングです。
・高い耐久性を持ち、消耗品としてのライフサイクルを長く取る事が出来る為、長期的に見た場合非常に経済的です。
・超仕上げ工程や内外径研磨に使用する砥石の管理を厳密に行う事で回転時の抵抗感を限りなく0に近付けてある為、純粋なコーナリング速度が向上します。
・小型RCカーの軸周辺部品及びフェンスカーのローラーに採用する事でコーナリング性能が劇的に変化します

■ISC HG 520 Ball Bearing (Set of 4)

• ISC (Industrial Supply Company) is a part of NSK Micro Precision Co., Ltd., which belongs to the NSK Ltd. Group—a world leader in the bearing business, holding the top market share in Japan and the third globally.

• This is a high-performance bearing manufactured in Japan, adopting a metal retainer that delivers significantly higher precision and greater durability than previous resin retainers.

• Due to its high durability, the bearing offers a long lifecycle as a consumable part, making it highly economical in the long run.

• Through an advanced super-finishing process and strict management of the grinding wheels used for inner and outer diameter polishing, rotational resistance is brought nearly to zero, resulting in a pure increase in cornering speed.

• By adopting this bearing for parts around the axle of small RC cars and for the rollers of fence cars (Fencesitter cars), cornering performance can be dramatically improved.

YT-004用のスペア軸受で、YT-004に同梱のものと同じものとなります。
国産の高精度ベアリングにガタツキ防止の油膜処理を施しております。

また、YUTORIRACINGがフェスカーの軸受に使用しているものと同じものになります。

■620 Ball Bearing (Set of 2)

This is a spare bearing for the YT-004, identical to the one included with the YT-004 unit.

It features a Japanese-made, high-precision bearing treated with an oil film to prevent looseness (play).

Furthermore, it is the exact same bearing used by YUTORIRACING for the axles of their Fence Cars.
