Both ball bearings and roller bearings are one of the most common types of ball bearings. The ball bearings are mounted between the inner and outer rings and are capable of withstanding heavy loads. Also called ball bearing. The roller bearing supports a rotating part using rolling contact between the main parts. Different roller bearings can bear different radial and axial forces. So what are the basic differences between the two types of bearings in use?

Ball bearing and roller bearing are two basic types different from roller bearing

1. Ball → ball bearing.

2. Roller → Roller Bearing.

Ball bearing and roller bearing contact the raceway in different ways

The ball makes point contact with the raceway of the bearing ring. As the load acting on the bearing increases, the contact becomes an elliptical region. A small contact area reduces rolling friction, which allows ball bearings to adapt to high speeds while limiting their load-carrying capacity.

The roller makes line contact with the raceway of the bearing ring. As the load acting on the bearing increases, the contact line becomes a rectangle. Because of the larger contact area and the resulting increased friction, roller bearings can withstand heavier loads but at lower speeds than ball bearings of the same size.

The range of applications for ball bearing and roller bearing is different

Ball bearings are widely used in precision instruments, low-noise motor, automobile, motorcycle, and general machinery industries, and is the most widely used in the mechanical industry a bearing.

The roller bearing is mainly used in large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearbox, rolling mills, vibrating screens, and lifting and transportation machinery.
