Diseñado para un rendimiento de carga radial y axial a alta velocidad
El rodamiento de bolas de contacto angular {{ZKF_2}} 7220 está diseñado para manejar cargas radiales y axiales combinadas en aplicaciones que operan a velocidades moderadas a altas. Con su configuración de una sola fila y diseño de sello abierto, sobresale en husillos de motores eléctricos y cajas de engranajes donde la lubricación eficiente (grasa o aceite) y la disipación de calor son esenciales. La construcción de acero para rodamientos proporciona la durabilidad necesaria para la operación industrial continua.
Detalles técnicos que maximizan el tiempo de actividad del equipo
Las dimensiones de 100 mm de diámetro de perforación, 180 mm de diámetro exterior y 34 mm de ancho del rodamiento {{ZKF_2}} 7220 proporcionan una distribución de carga óptima para maquinaria industrial. Su diseño de contacto angular permite un ajuste preciso de la precarga, lo cual es crítico para minimizar la vibración y extender la vida útil del equipo. A diferencia de las alternativas falsificadas, los rodamientos genuinos {{ZKF_3}} mantienen tolerancias dimensionales estrictas, asegurando un ajuste adecuado y reduciendo el desgaste prematuro en aplicaciones de alto par.
Evite los Costos Ocultos de los Rodamientos Falsificados
Non-genuine bearings may save on initial cost, but they often fail within months—costing far more in production downtime, repair labor, and damaged equipment. Our NTN 7220 single row angular contact bearing comes with complete traceability documentation, eliminating customs clearance delays and quality liability disputes. When you factor in longer service life and reduced maintenance, genuine bearings deliver lower total cost of ownership.
