1.3 Bearing Types and Materials

6006 bearings are available in various types to suit specific application requirements. Common types include:

• Open bearings: No seals or shields
• Shielded bearings: One or both sides shielded to prevent ingress of dust and debris
• Sealed bearings: Contact or non-contact seals on both sides to retain lubricant and exclude contaminants

Materials used in the construction of 6006 bearings include:

• Bearing steel: Provides high strength and hardness
• Stainless steel: Resists corrosion
• Ceramic: Offers exceptional wear resistance and high-temperature tolerance

1.4 Bearing Load Capacity

The load capacity of a 6006 bearing refers to its ability to withstand applied loads without failure. It is typically expressed in terms of dynamic load rating (C) and static load rating (C0).

The dynamic load rating is the load that can be applied to the bearing for 1 million revolutions without causing fatigue failure. The static load rating is the maximum load that can be applied to the bearing without causing permanent deformation.
