The rolling contact bearings are known as antifriction bearings.
Explanation:
Rolling contact bearings, also known as antifriction bearings, are a type of bearing that use rolling elements to reduce friction between moving parts. They are designed to carry radial and axial loads and are commonly used in various applications, including automotive, industrial machinery, and aerospace.
Key Points:
Here are some key points about rolling contact bearings:
1. Function: The main function of rolling contact bearings is to support and guide rotating or oscillating shafts or axles, while minimizing friction and allowing smooth motion.
2. Rolling Elements: Unlike plain bearings, which use sliding surfaces to reduce friction, rolling contact bearings use rolling elements such as balls or rollers. These rolling elements are typically made of steel or ceramic and are housed within an inner and outer race.
3. Reduced Friction: The rolling action of the elements between the races reduces the frictional forces compared to sliding contact bearings. This results in lower energy consumption, reduced heat generation, and improved efficiency.
4. Types: There are various types of rolling contact bearings, including deep groove ball bearings, cylindrical roller bearings, tapered roller bearings, and spherical roller bearings. Each type is designed to accommodate different load capacities and operating conditions.
5. Lubrication: Rolling contact bearings require lubrication to reduce friction and prevent wear and damage. Different types of lubricants, such as grease or oil, can be used depending on the application and operating conditions.
6. Advantages: The use of rolling contact bearings offers several advantages, including higher load-carrying capacity, lower friction and wear, smoother operation, and longer service life compared to plain bearings.
7. Limitations: Despite their advantages, rolling contact bearings also have limitations. They require careful design and installation to ensure proper alignment and load distribution. Additionally, they may require periodic maintenance, including lubrication replenishment and bearing inspection.
In conclusion, rolling contact bearings, also known as antifriction bearings, are widely used in various applications due to their ability to reduce friction and support rotating or oscillating shafts. They offer several advantages over plain bearings, including lower friction, higher load capacity, and longer service life.
