Four Point Contact Ball Slewing Bearing
El rodamiento de giro de bolas de contacto de cuatro puntos está compuesto principalmente por un anillo interior, un anillo exterior, bolas de acero de una sola fila, jaula (o separador), dispositivo de sellado y otras partes. El anillo interior y el anillo exterior del rodamiento de giro de bolas de contacto de cuatro puntos tienen estructuras integrales y divididas. La rigidez del aro integral es relativamente fuerte, y el tipo dividido es fácil de ajustar. La estructura dividida utiliza pernos para conectar los dos anillos divididos antes de que el producto salga de fábrica. Los rodamientos de giro de bolas de contacto de cuatro puntos generalmente tienen jaulas (o separadores). La estructura de bolas llenas solo se usa cuando la carga es relativamente grande. El rodamiento de bolas de contacto de cuatro puntos lleno tiene una gran capacidad de carga, pero una gran resistencia a la fricción. La fricción también puede causar fácilmente rayones en la capa superficial de la bola de acero. La estructura básica del rodamiento de giro/anillo de giro de bolas de contacto de cuatro puntos: con o sin engranajes, engranajes externos e internos, con alta capacidad de carga estática.
