Mejores proveedores de rodamientos al por mayor con servicio personalizado, proveedor de rodamiento JNSN su socio ideal.
Los tipos completos de rodamientos B y BH son rodamientos de rodillos de aguja estilo pulgadas, y ambos tipos son rodamientos de copa abiertos con agujas, mientras que M y MH son los rodamientos de gama cerrada. En comparación con la serie B, el diámetro exterior para los cojinetes de rodillos de aguja BH es más grande, pero el ancho y el tamaño del orificio son los mismos.
Los rodamientos B y BH consisten en agujas que se extienden a la vía de pista externa, por lo que tienen una alta carga. Estos rodamientos se aplican a la situación en la que los dispositivos montados con rodamientos de agujas corren en operación de balanceo con velocidad baja y media.
Los labios girados hacia adentro de la copa se usan para retener mecánicamente el complemento completo de los rodillos de aguja, proporcionando su retención radial positiva, a pesar de que puede ser necesario eliminar el eje repetidamente durante el servicio del mecanismo que emplea el rodamiento.
Aplicación
Los cojinetes de rodillos de aguja se utilizan en una variedad de aplicaciones, desde maquinaria agrícola hasta equipos de transmisión, robótica, equipos dentales, ascensores, molinos, pozos de timón y trituradores agregados, entre otros.
