ball bearings are the most common type of roller bearings. It is characterized by low friction resistance and high speed. It can be used for parts bearing radial loads or combined radial and axial loads at the same time, and can also be used for parts bearing axial loads, such as low power motors, automotive and tractor transmissions, machine tool transmissions, generally machinery, tools, etc.
What is the performance difference between ball bearings and roller bearings?
How to install and remove ball bearings?
Why do people choose ball bearings?
1. ball bearings: are generally used in low load mechanical transmissions. Since the bearing area of the ball bearing is small, heavy mechanical damage can easily occur in high-speed operation. Therefore, needle bearings are often used in heavy load mechanical transmission to increase bearing surface area, improve mechanical transmission efficiency and reduce mechanical damage.
2.Roller bearings: Roller bearings can achieve good precision and rigidity by preloading. And the inner ring with cone can also be used to adjust the working clearance of the bearing as desired. This type of solution can fully meet the zero clearance requirement of pressure cylinder bearings.
When installing the ball bearing, do not hit directly the end face and the non-stressed surface of the bearing. Use plungers, sleeves or other mounting tools (tools) to load the bearing evenly and do not install it by the transmission force of rolling elements. When the mounting surface is lubricated, the installation becomes smoother. If the interference is large, the ball bearing should be heated to 80° to 90° C in mineral oil and installed as soon as possible, and the oil temperature should be strictly controlled to not exceed 100° C, to prevent the tempering effect from reducing the hardness and affecting the size recovery. In case of difficulties in disassembly, it is recommended to carefully pour hot oil onto the inner ring with the disassembly tool, pulling outwards. The heat causes the inner ring of the bearing to expand and fall off more easily.
1.The sensitivity of ball bearing deformation to load changes is lower than that of hydrodynamic bearings;
2.The ball bearing only needs a small amount of lubricant to function normally, and can provide lubricant for a long time during operation.
3.The axial dimension of the ball bearing is smaller than that of the conventional hydrodynamic bearing;
4.The ball bearing can bear the combined radial and axial loads at the same time;
5.The unique design of the ball bearing can achieve excellent performance in a wide load speed range;
6.Bearing performance of ball bearings is relatively insensitive to load, speed and operating speed fluctuations.
