Spring quality: The spring is an important component of the radial shaft seal, providing pressure between the sealing lip and the shaft to ensure sealing effectiveness. High quality springs should have appropriate elasticity and strength, maintain stable performance over long-term use, and be less prone to fatigue fracture.
Sealing lip details: The shape, size, and flexibility of the sealing lip are crucial to the sealing performance. Some sealing lips may have special designs, such as lip chamfers, reinforcement ribs, or specific arcs, to improve sealing effectiveness and reduce wear. At the same time, it is necessary to ensure that the material of the sealing lip is compatible with the working medium and environment, avoiding problems such as swelling, hardening, or embrittlement.
Skeleton structure: A metal or plastic skeleton is used to support the overall structure of the seal, ensuring its shape and stability during installation and use. Check the material and manufacturing process of the skeleton to ensure it has sufficient strength and stiffness to prevent deformation or rupture of the seals.
Compatibility with shafts: In addition to size matching, factors such as shaft material, surface roughness, and hardness should also be considered. Shafts made of different materials may have different friction and wear effects on seals, for example, stainless steel shafts and carbon steel shafts may have different requirements for seals. The surface roughness of the shaft should meet the requirements of the seal. Generally speaking, a surface that is too rough can cause premature wear of the sealing lip, while a surface that is too smooth may affect the sealing effect.
Compatibility with lubricants: If seals are used in systems containing lubricants, ensure that the seal material is compatible with the lubricant used. Some lubricants may corrode or specific rubber or plastic materials, thereby damaging the sealing performance. For example, the compatibility of nitrile rubber seals in certain synthetic lubricants may not be as good as that of fluororubber seals.
Compatibility with equipment: Consider the overall design and operational requirements of the equipment to ensure that the radial shaft seal can fit well with other components of the equipment. For example, in some compact device structures, it may be necessary to choose thin or specially designed radial shaft seals to accommodate space limitations
