Ball Bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. Choosing the correct type of bearing during the design stage is crucial to ensure that your machine works safely and efficiently. It is therefore important to consider all operational parameters, such as the dimensions, rotational speed, material, lubrication/seals and the required service life, when choosing the correct bearing.

  1. Step 1: Outer Ring

    Create an outer ring as per the dimension. Use revolve command to make the ring easily without much time. Define your sketch. A fully defined sketch will be black as shown above.

    Add fillet to avoid sharp edges along the curve. Finally define the material.

  2. Step 2: Inner ring

    Same as outer ring, use revolve command and create the inner ring. Make sure sketch is fully defined.

    Define the material.

  3. Step 3: Cage

    Create and define the sketch according to the dimensions of the cage and extrude it.

    After boss-extrusion, create a sketch for ball seating, cut-extrude it.

    Pattern it to the required number. USe command circular pattern.

    Shell it to the required thickness, use shell command and select the faces to shell.

    create sketch for fixing rivets and cut extrude it and finally circular pattern it.

    Cage !!!

  4. Step 4: Balls

    Create a sketch as shown above and revolve it to create the ball for the bearing.

  5. Step 5: Ball Bearing

    Finally Assemble the components to create a ball bearing.
