Introduction To Outer Spherical Bearings

The outer spherical bearing product has the following requirements:
1. Material requirements
Outer spherical bearings mainly consist of inner rings, outer rings, and balls. The inner and outer rings are generally made of high-strength steel, cast iron, and other metal materials, while the balls are made of high-strength steel, alloys, and other materials. The selection of materials should consider factors such as their strength, hardness, wear resistance, corrosion resistance, and manufacturing cost.
2. Accuracy requirements
For external spherical bearings, important accuracy indicators include geometric accuracy, axial clearance, and shrinkage. Geometric accuracy corresponds to the dimensional accuracy of bearing machining, axial clearance reflects the degree of freedom of the bearing during operation, and shrinkage refers to the degree of deformation of the bearing under load. These precision indicators require very high requirements and require strict processing techniques and quality control to ensure.
3. Requirements for bearing capacity
The load-bearing capacity of an outer spherical bearing is one of its most important properties. Its load-bearing capacity depends on factors such as material selection and accuracy, as well as its structural form, number and size of balls. The bearing capacity requirements of outer spherical bearings vary depending on different working conditions and loads. Therefore, when selecting outer spherical bearings, it is necessary to determine their load-bearing capacity requirements based on actual operating conditions and loads.
4. Wear and fatigue requirements
Outer spherical bearings are subject to wear and fatigue during use. Among them, wear is mainly caused by friction and abrasive on the bearing surface, while fatigue is caused by the bearing being under heavy load for a long time. In order to extend the service life of outer spherical bearings, special treatments such as hard electroplating are required on the bearing surface, while improving the strength and hardness of the material.
5. Sealing and lubrication requirements
The normal operation of outer spherical bearings requires sufficient lubrication and sealing. In harsh environments such as high temperatures and speeds, special lubrication and sealing measures are required to ensure the normal operation of bearings. The commonly used lubrication methods include oil lubrication and grease lubrication, and the commonly used sealing methods include rubber sealing and metal sealing.
6. Installation and Maintenance Requirements
The installation and maintenance of outer spherical bearings have a significant impact on their performance and lifespan. During installation, it is necessary to ensure the accuracy of the fit between the bearing and the seat hole, and to add bearing preload while ensuring sufficient lubrication to ensure the normal operation of the bearing. During maintenance, regular lubrication and cleaning are required, and failed bearings should be replaced in a timely manner. In addition, it is necessary to follow the instructions for correct use to avoid bearing failure caused by incorrect operation.
In summary, the product requirements for outer spherical bearings cover materials, accuracy, load-bearing capacity, wear and fatigue, sealing and lubrication, as well as installation and maintenance. These requirements require strict manufacturing and quality control to ensure the performance, lifespan, and reliability of bearings.
