These ceramic bearings are a special edition of the esteemed and robust Bones Reds bearings. Thanks to the ceramic balls, the bearings are lighter and sturdier, which prolongs the bearing's lifespan. The ceramic balls resist rust and can typically crush any sand that enters the bearing.
However, you should still avoid exposing them to sand and water as this will always significantly reduce the bearing's lifespan, especially if you do not clean the bed afterwards. Furthermore, it is important to note that the metal ring encircling the bearing can still rust.
Here is what they state on the bearing:
- Contains grade 5, silicon nitride, hot isostatically pressed ceramic balls.
- Higher quality steel races with a superior surface finish.
- Single, non-contact, removable rubber shield for easier cleaning and reduced friction.
- High-speed nylon ball retainer for greater strength and speed.
- Pre-lubricated with Speed Cream ™ racing lubricant.
- Skate Rated ™ clearances, tolerances, materials, and lubricant provide the best possible performance and durability.
