Rodamiento giratorio de bolas de contacto de cuatro puntos
El rodamiento giratorio de bolas de contacto de cuatro puntos se compone principalmente de anillo interior, anillo exterior, bolas de acero de una hilera, jaula (o espaciador), dispositivo de sellado y otras partes. El aro interior y el aro exterior del rodamiento giratorio de bolas de contacto de cuatro puntos tienen estructuras integrales y divididas. La rigidez de la férula integral es relativamente fuerte y el tipo dividido es fácil de ajustar. La estructura dividida ha utilizado pernos para conectar los dos anillos divididos antes de que el producto salga de fábrica. Los rodamientos giratorios de bolas de contacto de cuatro puntos generalmente tienen jaulas (o espaciadores). La estructura de bola llena solo se usa cuando la carga es relativamente grande. El rodamiento de bolas de contacto de cuatro puntos completamente lleno tiene una gran capacidad de carga, pero una gran resistencia a la fricción. La fricción también puede causar arañazos fácilmente en la capa superficial de la bola de acero.
