The balls are ceramic and are really good right upto the point they get dust or anything in em then the balls somehow disappear lol

Its the balls

straight from wiki - i am a plagarist (is that a real word? lol)

Ceramic bearing balls can weigh up to 40% less than steel bearing balls, depending on size and material. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate 20% to 40% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling resistance. The lighter ball allows the bearing to spin faster, and uses less energy to maintain its speed.
Ceramic hybrid ball bearings use these ceramic balls in place of steel balls. They are constructed with steel inner and outer rings, but ceramic balls; hence the hybrid designation.

I find RC bearings pretty good and have better prices than model fixings.

They do have some ceramic bearings - not sure if you have the sizes you need though
