El propósito derodamientos rígidos de bolaslubrication is to form a thin oil film on the surface of the ring and rolling elements to prevent direct metal contact, thereby avoiding wear and shortening the bearing life. In addition, the lubricant reduces the noise and friction during bearing operation, improving the efficiency of the bearing. operating characteristics, in addition to wear protection and heat dissipation functions.
Commonly used lubricants include lubricants and greases. The correct lubricant should be selected according to different applications and different environments to optimize bearing performance.
Los lubricantes de grasa son más fáciles de usar que los lubricantes de aceite debido a su viscosidad, son más duraderos y solo requieren un equipo de sellado simple. La grasa es difícil de cambiar porque la práctica común es forzar la entrada de la grasa en el dispositivo, permitiendo que la grasa nueva exprima la grasa vieja. En términos generales, la grasa con aceite base de baja viscosidad es más adecuada para operaciones a baja temperatura y alta velocidad, mientras que la grasa con aceite base de alta viscosidad es adecuada para cargas pesadas.
Oil lubrication is more suitable for use under high-speed and high-temperature conditions, as it can effectively take away the heat during bearing operation.
The viscosity of oil determines the effectiveness of oil lubrication. If the viscosity is too low, the oil film formation will be insufficient; if the viscosity is too high, the viscous resistance will increase and the temperature rise will increase. Generally, the greater the rotation speed, the lower the viscosity of the lubricating oil; the greater the load, the higher the viscosity of the lubricating oil.
Los NSAR se utilizan ampliamente en electrodomésticos. micromotores herramientas eléctricas maquinaria de jardín, motocicletas, automóviles, equipamiento médico, maquinaria deportiva, maquinaria textil y maquinaria agrícola.
Todos los rodamientos que fabricamos son de bajo ruido, baja vibración, baja fricción, alta precisión, alto sellado, alta velocidad de giro y larga vida útil.
Quality is the key point for the NSAR. bearing’s growth and development, which always regards the improvement of high quality and service as the long-term-development strategy. NSAR has passed IS09001: 2000, 1S09001: 2008, and will struggle for the NSAR in long term.
