This is the kit of ten 8x16x5mm Select NMB bearings with ZZ metal shields from Ultimate Racing.
They are manufactured by the prestigious Japanese brand NMB.
The ball cage is metal to achieve greater durability.
The balls are large to prevent them from getting easily stuck with dust.
Made from high-quality steel to avoid easy scratching or pitting of the races and balls. This way, simply cleaning the bearing will make it spin smoothly as if it were new.
