Ultimate Racing 8x16x5 ZZ (10U.) Bearings

NMB Select 8x16x5 Bearings

These are 8x16x5 bearings with metal shields (ZZ) from Ultimate Racing, manufactured since 2023 by one of the world’s most prestigious bearing producers, NMB Technologies, a Japanese company specialized in high-quality bearing manufacturing.

Compared to the previous model, the entire bearing is now made from high-grade steel — cage, balls, and structure — which provides greater durability. The design is also different, featuring larger balls that can perform much more effectively in dusty conditions. Additionally, they require less maintenance, and when maintenance is needed, it’s much easier to carry out. The hardness of the steel prevents damage to the balls or raceways, which would otherwise compromise the bearing’s performance. As a result, restoring the bearing is as simple as cleaning it and applying good bearing oil, and it will spin like new again.

All these features make the Ultimate Racing 8x16x5 bearings the best on the market.
