In security cameras, the bearings used are usually part of the motor assembly that powers the lens or pan-and-ti

mechanisms. Here's a brief overview of the types of bearings commonly found in these devices:

Ball Bearings:

Function: Provide smooth and precise rotation.

Advantages: High precision, durability, and ability to handle radial and axial loads.

Application: Often used in motors that need to operate quietly and reliably over long periods.

Sleeve Bearings:

Function: Provide a simple and cost-effective solution for rotation.

Advantages: Lower cost and simpler design.

Application: Typically used in lower-speed or less critical components.

Magnetic Bearings(less common):

Function: Use magnetic fields to support the rotating components without physical contact.

Advantages: Reduced friction and wear, potentially longer lifespan.

Application: More advanced or high-end security cameras might use these for very precise movements.
