Bearings

Bearings are mechanical components that enable rotational or linear movement while reducing friction between moving parts. They are crucial in various machines, equipment, and mechanisms to allow smooth and controlled motion. Bearings are widely used in industrial, automotive, aerospace, and everyday applications. There are several types of bearings, each designed for specific purposes:

  1. Ball Bearings:

    • The most common type of bearing.
    • Consists of small steel balls arranged between two rings (inner and outer).
    • Provides low friction and supports radial and axial loads.
    • Suitable for moderate-speed applications.

  2. Roller Bearings:

    • Similar to ball bearings but with cylindrical or tapered rollers instead of balls.
    • Handles heavier loads and provides greater contact surface area.
    • Available in various configurations, including cylindrical, tapered, and needle rollers.

  3. Thrust Bearings:

    • Designed to handle axial loads (forces parallel to the shaft).
    • Used in applications where there's a need to support loads in one direction.

  4. Tapered Roller Bearings:

    • Handles both radial and axial loads.
    • Often used in pairs to support high axial loads in both directions.

  5. Spherical Roller Bearings:

    • Designed to accommodate misalignment and heavy radial and axial loads.
    • Contains barrel-shaped rollers that can handle dynamic and static loads.

  6. Needle Bearings:

    • Have a small diameter compared to their length.
    • Used in applications with limited radial space and high load capacity.

  7. Plain Bearings (Bushings):

    • Offer sliding rather than rolling motion.
    • Often made of materials like bronze, plastic, or self-lubricating materials.

  8. Linear Bearings:

    • Used in linear motion applications where smooth and accurate movement is required.
    • May include linear ball bearings, linear roller bearings, and linear bushings.

  9. Angular Contact Bearings:

    • Designed to handle combined radial and axial loads.
    • Supports high-speed applications.

  10. Mounted Bearings:

    • Bearings housed in a mounting unit.
    • Used to provide support and facilitate motion in specific applications.
