Steel bearings use conventional ball and race materials; ceramic models pair ceramic balls with steel races in the Bones examples compared here. Select by the exact product specification and maintenance needs.
Bearing materials are only one part of a skateboard bearing. Shield design, lubrication, fit and maintenance also affect how a set behaves. These examples use Bones products because the manufacturer publishes component details for both.
| Feature | Bones Super REDS | Bones Ceramic REDS |
|---|---|---|
| Balls | Product page lists higher-quality, higher-grade balls; it does not specify their material | Grade 5 silicon nitride ceramic balls |
| Races | Higher-quality steel races | Steel races with a superior surface finish |
| Shield | Single, non-contact removable rubber shield | Single, non-contact removable rubber shield |
| Retainer | High-speed nylon retainer | High-speed nylon retainer |
| Lubricant | Pre-lubricated with Speed Cream | Pre-lubricated with Speed Cream |
Ceramic REDS keep steel races while using ceramic balls. The manufacturer states that the ceramic balls do not rust and describes them as lighter than steel balls. That product-specific feature may suit someone who wants the ceramic construction, but it does not make every ceramic bearing maintenance-free. Dirt and moisture can still affect the other components.
Super REDS use steel races and the maker’s specified higher-grade balls. This is the conventional bearing choice for a skater who wants an accessible, shielded set and is willing to clean and lubricate it as directed. The product maker’s performance descriptions are not a guarantee of speed or service life in a particular setup.
Choose by exact pack contents, shield access, lubrication, replacement availability and your conditions. Avoid treating ABEC numbers as a substitute for skateboard-specific component details. Clean bearings when needed and keep them dry, following the maker’s maintenance instructions.
For the standard size, fit and maintenance basics, see skateboard bearings and ABEC ratings. The wheel hardness and size guide helps match the bearings to the rest of the setup.

Common questions
Do ceramic skateboard bearings have steel races?
In the Bones Ceramic REDS example, the manufacturer lists Grade 5 silicon nitride ceramic balls and steel races. Check the exact product.
Are ceramic bearings faster?
Manufacturers make performance claims for specific products, but speed depends on setup, cleanliness, lubrication and riding conditions.
Do ceramic balls rust?
Silicon nitride ceramic balls do not rust, but a bearing can still include steel races. Keep the complete bearing clean and dry.
