Se recomienda encarecidamente que las grandes excavadoras o minas con m\u00e1s de 20 toneladas de trituraci\u00f3n condiciones de trabajo elegir 42CrMo material.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      P3: \u00bfCu\u00e1l es el embalaje de env\u00edo del producto, puede evitar la oxidaci\u00f3n por mar?\n    <\/div>\n    <div class=\"faq-answer\">\n      La superficie del producto se recubrir\u00e1 con aceite antioxidante, se envolver\u00e1 con una capa de pel\u00edcula de pl\u00e1stico, se envolver\u00e1 con una capa de papel kraft y, por \u00faltimo, se colocar\u00e1 en una caja de madera contrachapada no fumigada para su fijaci\u00f3n. Este embalaje protector de cuatro capas se ajusta plenamente a las normas internacionales de transporte y garantiza un periodo de protecci\u00f3n contra la oxidaci\u00f3n de m\u00e1s de 12 meses.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      P4: Si no estoy seguro del n\u00famero de pieza, \u00bfc\u00f3mo puedo confirmar que tambi\u00e9n he comprado el modelo correcto?\n    <\/div>\n    <div class=\"faq-answer\">\n      Puede proporcionar las 3 dimensiones clave del rodamiento antiguo: el di\u00e1metro exterior, el di\u00e1metro interior y la distancia central del orificio de montaje.

Para la miner\u00eda de rotaci\u00f3n frecuente o condiciones de trabajo con mucho polvo en el entorno de trabajo, recomendamos la selecci\u00f3n de productos de endurecimiento por inducci\u00f3n de la superficie de los dientes.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n     P6: \u00bfDurante cu\u00e1nto tiempo garantizan el cojinete de giro de la excavadora?\n    <\/div>\n    <div class=\"faq-answer\">\n       Para diferentes materiales y condiciones de trabajo, ofrecemos 12 meses o 2000 horas de trabajo de garant\u00eda de calidad.

Compared with ordinary 50Mn steel, the tensile strength is increased by 35%, and the low temperature impact toughness is enhanced, which effectively prevents brittle fracture in the cold mine operation environment."],"characteristics_description2":["The raceway adopts a CNC induction hardening process, and the depth of the hardened layer is precisely controlled between 3.5mm and 5mm. This deep hardening treatment ensures that the surface of the raceway does not peel off or collapse when subjected to alternating loads for a long time, and the fatigue life is 1.5 times that of the surface quenching product."],"characteristics_description3":["Gear processing adopts precision grinding process, the tooth surface roughness is controlled within Ra 3.2, and the gear accuracy reaches ISO 7 standard. The high-precision gear meshing significantly reduces the impact and noise during rotation, reduces the backlash wear of the tooth surface, and extends the life of the pinion shaft by about 20%."],"characteristics_description4":["Equipped with high-temperature and oil-resistant high-performance nitrile rubber double-lip sealing strip. The sealing structure can effectively prevent coal ash, sand dust and moisture from invading the inside of the raceway, prevent the loss of grease, and improve the sealing performance of the bearing in dust environment by 90%."],"characteristics_description5":["Before leaving the factory, 100% of the axial and radial clearance is tested, and the clearance tolerance is controlled within the range of 0.03mm to 0.08mm. The precise preload design eliminates the shaking of the slewing device and ensures that the excavator moves smoothly without frustration during fine leveling operations."],"characteristics_description6":["Each set of excavator slewing bearing has been double tested by ultrasonic flaw detection and magnetic particle flaw detection.

This means that the core of the product has better strength and toughness, and can resist the severe impact of excavator operation without deformation. In addition, our tooth surface adopts segmented induction hardening, which avoids the soft belt docking problem easily caused by traditional full-circle quenching and ensures the 360-degree hardness of the gear."],"comparison_points_description1":["The stress concentration of the tooth root was eliminated by optimizing the radius of the tooth root fillet and strengthening the tooth root by shot peening. With the high toughness of 42CrMo material, the problem of tooth breakage caused by excessive instantaneous impact load is completely solved when the excavator is digging hard rock or strong crushing."],"comparison_points_description2":["In view of the problem of sticking caused by the peeling of the old bearing raceway, we adopted the optimized raceway curvature design and high-precision steel ball selection. This not only reduces the friction heat between the raceway and the steel ball, but also effectively prevents the metal debris generated by fretting wear from jamming the raceway, and solves the problem of unsmooth rotation."],"comparison_points_description3":["In view of the oil leakage problem caused by the aging of the sealing strip, the labyrinth groove combined with the double lip seal structure is adopted. This design not only enhances the retention of internal grease, but also solves the problem of emulsification and deterioration of grease due to muddy water entering the raceway through the failed sealing ring."],"application_title":["excavator slewing ring bearing Applicable crowd"],"application_title1":["Excavator machine manufacturing factory purchasing department"],"application_title2":["Construction machinery after-sales maintenance and renovation service providers"],"application_title3":["Mine and large earthwork contractors"],"application_title4":["International engineering machinery parts trade agent"],"application_describe1":["It is suitable for engineering machinery OEMs that need to find OEM supporting standards and have stable batch supply capacity.
