In lithium electric tools, bearings play a crucial role in ensuring smooth operation,reducing friction, and extending the

tool's lifespan. Here are the key considerations for bearings used in these tools:

1. Types of Bearings

Ball Bearings:Commonly used due to their ability to handle both radial and axial loads with low friction.They are

suitable for high-speed applications typical in electric tools.

Roller Bearings: These can handle heavier loads compared to ball bearings but might be less suitable for high-speed

applications.

2. Materials

Steel Bearings:Traditional and cost-effective, but they might not be as durable under extreme conditions.

Ceramic Bearings: Offer better performance in terms of heat resistance and durability. They are more expensive but

can improve the tool's performance and longevity.

Hybrid Bearings:Combine ceramic balls with steel races,providing a balance between cost and performance.
