What are the advantages of deep groove ball bearings? (1)

1. The property of preventing adhesion and forming boundary lubrication when the shaft diameter is in direct contact with the bushing. The factors that affect the friction compatibility of the friction pair are:
(1) The difficulty of forming alloys in the metallurgical process of auxiliary materials.
(2) Affinity of materials and lubricants.
(3) The friction coefficient of non-lubricating materials.
Material organization.
(5) Thermal conductivity of the material.
(6) The size of the surface energy and the characteristics of the oxide film.
2. Embedding
The ability of the material allows foreign hard particles to be clamped in the lubricant to prevent scratches and/or wear. Suitable for metal materials, low hardness, low modulus of elasticity, good clamping, but non-metallic materials such as graphite carbon, low modulus of elasticity, poor clamping. Deep groove ball bearings usually use soft materials and hard materials to form friction pairs, and usually use soft materials as bearings.
3. Compatibility
In the grinding process of the shaft diameter and the sleeve, the machining error, coaxiality error, surface roughness parameter value of the shaft diameter and the sleeve are reduced to make the contact uniform, thereby reducing the friction and wear ability.
4. Friction adaptability
Due to poor initial coordination of the sliding friction surface and poor bending performance of the shaft, the material is compensated by the elastic-plastic deformation of the surface layer. Low elastic modulus materials have good adaptability.
5. Wear resistance
The ability to resist wear. Under the prescribed wear conditions, the wear rate or degree of wear, the amount of wear indicates wear resistance.
6. Fatigue
The ability of a material to fatigue damage under cyclic loading. The strength, hardness, strength, hardness, impact resistance and uniformity of the material are very important in combating fatigue. Materials with good abrasion resistance and resistance to penetration of clamps are generally poor.
