Ball Bearing Designs and Uses
There are many types of ball bearings and each design has different uses and purposes.
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. There are many types of ball bearings and each design has different uses, designs, and purposes. Here is a brief overview of some of the more popular ball bearings:
- The single row deep groove ball bearing is the largest sales volume of all bearing designs. Because of the shoulders on each side of the groove, the single row, deep groove ball bearing can take both thrust and radial loads.
- In the angular contact bearing, there is a shoulder on just one side of the groove. Because of this, an angular contact bearing can only take thrust from one direction.
- The double row angular contact bearing can take thrust from both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments.
- Thrust ball bearings primarily carry thrust loads, but also provide axial shaft location. They provide optimum performance in high-speed applications, particularly where loads are generally lighter.
- Radial ball bearings are the simplest and most common anti-friction bearing. This is because unlike many ball bearing designs, the radial ball bearing only has a single row of balls around the race.
- The Conrad deep groove ball bearing design is assembled by placing the inner ring into an eccentric position relative to the outer ring, with the two rings in contact at one point, resulting in a large gap opposite the point of contact.
