  • Abec 3
  • Pre Greased
  • Chrome steel
  • Rubber sealed


440 Stainless Steel   * 10x15 Flange will NOT be stainless

Stainless Steel bearings offer 75-85% of the strength as the Chrome Steel bearing, but will not corrode when used in wet applications. Stainless Steel also will run safely at a higher temperature than a chrome steel

  • Abec 3
  • Pre Greased
  • 440 Stainless Steel balls retainers & races
  • Rubber sealed


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.
