Excavator rolling bearing accessoriesExcavator Parts A bearing is a device used in machinery to reduce friction and wear between two relative moving surfaces. They work by securing an shaft to one or more bearing points, allowing the shaft to move smoothly while rotating while bearing a load.Machinery Parts Depending on the working principle and application, bearings can be divided into many types, including: 1. ** Ball bearings ** : The most common type, which reduces friction by rolling small balls (balls), suitable for light load and high-speed applications.
2. ** Roller bearings ** : Used to withstand large radial forces, such as applications in heavy machinery.
3. ** Needle roller bearings ** : For space-constrained applications, their small and compact design enables them to carry high loads.
4. ** Thrust bearings ** : specially designed to withstand axial forces, such as in pumps or compressors.
5. ** angular contact bearing ** : bear both radial force and axial force, and can withstand large inclined loads, often used in high-speed rotation applications.
6. ** sliding bearings ** : reduce friction through liquid or solid lubricants, suitable for heavy loads, low speed or high precision occasions.
