440 Stainless Steel   * 10x15 Flange will NOT be stainless

• 440 Stainless Steel balls retainers & races

Ceramic Hybrid 

Ceramic Hybrids last up to 10xs longer than Chrome Steel bearings.  These are used in applications where high speed, load and temperature are a factor. Ceramic balls are harder and rounder than stainless & chrome steel, so therefore they offer less rolling resistance. 

• Abec 5
• Light oil
• Ceramic Silicon Nitride Si3N4 balls
• Chrome steel races
• Chrome steel & reinforced nylon retainers
• Rubber sealed

Reinforced nylon retainers

Reinforced Nylon retainers can handle up to 60% more speed than a chrome steel retainer. Nylon retainers will lose their elasticity and become brittle in colder temperatures.
