Have you ever wondered what is the difference between roller bearings and ball bearings? At first glance, they may not seem so different. However, these seemingly similar bearings have different use cases.
Ball and roller bearings at podshipnik-shop.ru/brands/SKF/podshipniki-skf/, Also known as rolling bearings, are widely used in various industries.
Bearings have been around for hundreds of years and have many applications, some of which include electric motors, machine tools, household equipment, construction machinery, vehicles, skateboards, etc.
Bearings are used to provide rotary motion, reducing the amount of friction generated by rolling the two surfaces over each other. They consist of smooth metal balls or rollers that roll against a smooth inner and outer metal surface. The rollers or balls take the load, allowing the device to spin.
The load acting on a bearing is either a radial or an axial load. Depending on the location of the bearing in the mechanism, it can experience radial or axial loads, or a combination of both. For example, a bearing in a wheel of your car supports radial and axial loads.
Ball bearings are usually used for light loads. The contact points between the ball and the outer ring are very small due to the spherical shape of the bearing. It also helps the ball spin very smoothly. Because the contact point is so small, the bearing can be overloaded at a certain point, resulting in deformation of the ball bearing. This will destroy the bearing. Ball bearings are commonly used in applications where the load is relatively light.
Roller bearings are cylindrical bearings where the point of contact between the bearing and the frame is a line, not a point. The load is spread over a larger area and allows the bearing to handle a larger load. To minimize its tendency to skew.
