1. Material Grade
   The material used in the construction of sealed ball bearings significantly impacts their performance and durability. Common materials include stainless steel (e.g., AISI 440C), carbon steel, and ceramic. Stainless steel is preferred for its corrosion resistance, making it ideal for harsh environments, while ceramic bearings offer reduced weight and lower friction. Buyers should consider the operational environment and load requirements to choose the appropriate material grade.

2. Tolerance
   Tolerance refers to the allowable deviation in bearing dimensions and is critical for ensuring proper fit and function. Standard tolerances for sealed ball bearings are usually categorized as P0 (normal), P6 (medium), or P5 (high). Precision applications, such as in aerospace or medical devices, often require tighter tolerances to ensure reliability and performance. Understanding tolerance levels helps buyers assess the suitability of bearings for specific applications.

3. Dynamic Load Rating (C)
   The dynamic load rating is a measure of the bearing’s ability to support loads while in motion. It is expressed in kilonewtons (kN) and indicates how much load a bearing can handle before fatigue occurs. Selecting a bearing with an appropriate dynamic load rating is vital for ensuring longevity and preventing premature failure, particularly in high-load applications.

4. Seal Type
   The type of seal used in a sealed ball bearing affects its resistance to contaminants and retention of lubrication. Common seal types include rubber seals (RS) and metal shields (ZZ). Rubber seals provide better protection against moisture and dirt but may have higher friction, while metal shields offer less protection but lower friction. Buyers should evaluate the specific operational conditions to select the right seal type.

5. Operating Temperature Range
   The operating temperature range defines the conditions under which a bearing can perform effectively. Most sealed ball bearings operate efficiently between -40°C to +120°C. For applications involving extreme temperatures, specialized bearings may be required. Understanding the temperature tolerance helps prevent thermal degradation and ensures optimal performance.

6. Grease Type
   The type of grease used for lubrication can affect the performance and lifespan of sealed ball bearings. Common greases include lithium-based, polyurea, and synthetic greases, each offering different temperature and load capabilities. Selecting the appropriate grease type is essential for minimizing friction and wear, especially in demanding applications.

Common Trade Terminology
