Frictionless bearings come in various forms, each with its unique advantages and applications:

1. Air Bearings:

• Utilize compressed air to create a thin film between the bearing surfaces.
• Offer ultra-low friction and can handle high loads and speeds.
• Commonly used in precision instruments, semiconductor manufacturing, and medical devices.

2. Magnetic Bearings:

• Employ magnetic fields to levitate the rotating element.
• Provide frictionless operation and are well-suited for high-speed applications.
• Found in vacuum systems, turbomachinery, and aerospace components.

3. Fluid Film Bearings:

• Use a pressurized fluid (e.g., oil, water) to create a thin film between the surfaces.
• Offer high load capacities and can accommodate misalignment.
• Widely used in large machinery, turbines, and gearboxes.
